Mount Whitney  is the highest summit in the continuous United States with an elevation of 14,497 feet above the sea. It is located between California's Inyo and Tulare counties, just 76 miles west of the lowest point in North America, Badwater in Death Valley National Park (-282 feet). The western slope of the mountain lies within Sequoia National Park and the summit is the southern terminus of the John Muir Trail which runs 211 miles from Happy Isles in Yosemite Valley. The summit of Whitney lies along the Sierra Crest and near many of the highest peaks of the Sierra Nevada. Water that falls to the west of the crest flows into the Pacific Ocean, while water that falls to the east flows into the Great Basin. The peak rises 10,778 feet above the town of Lone Pine in the Owens Valley below. The Mount Whitney Trail (class 1)  is the easiest and most popular route to the summit. The trail starts at Whitney Portal (8,360 feet), 13 miles west of the town of Lone Pine. The trail is about 22 miles round trip with an elevation gain of over 6,100 feet. Most hikers will take between 2 and 4 days to complete this trip, although it is often done as a strenuous day hike taking anywhere from 10-20 hours. Permits are required year round for anyone entering the Mt. Whitney Zone.


Trail Description

1. Whitney Portal- Mile 0.0- 8,300'  The trail starts just below the Whitney Portal Store through a hallway of information signs. The trail ascends a number of long switchbacks passing Carillon Creek and the North Fork of Lone Pine Creek then continues to switchback & transverse the northerly wall of Lone Pine canyon. You then head into a forested area as you approach Lone Pine Lake.
 
2. Lone Pine Lake- Mile 2.8- 10,000'  Shortly after the log crossing over  Lone Pine Creek, you will pass a sign for the turn off to Lone Pine Lake.  A permit is required beyond this point. After the fork to the lake, switchbacks take you up the westerly end of the canyon to the next level. The trail then skirts the south side of Big Horn Park on the way to Outpost Camp.

3. Outpost Camp- Mile 3.8- 10,300'' At the far end of Bighorn Park is a waterfall, a creek crossing, and Outpost Camp. After another creek crossing the trail then switchbacks up to the next level where you pass Mirror Lake. Above Mirror Lake the trail ascends above the tree line and transitions into a rock path. In this area the trail is more rugged as you gain elevation and pass by Trailside Meadow. As the trail switchbacks out of Trailside Meadow, Consultation lake comes into view.
 
4. Trail Camp- Mile 6.0- 12,000'  The trail passes through Trail Camp, delineated by a rock boundary to the south and a small pond to the north. The stream feeding the Trail Camp Pond is the last easy area to get water before heading to the summit. After passing through Trail Camp you arrive at the 97-switchbacks. In the area of switchbacks 23-25 there is usually water flowing over the trail from a spring and snow melt higher up the slope. This area may be icy at times. After switchback #45 you will enter the area with the cable railing. This area may also be icy and can hold snow well into summer. After switchback #97 there is a long traverse (heading slightly down hill) over to Trail Crest.

5. Trail Crest- Mile 8.2- 13,600'  The trail then travels to the west side of the crest as it descends to the John Muir Trail junction then starts to climb again and passes below Mt. Muir. After passing several windows, the next section of the trail goes up several switchbacks as you approach the ridge line and traverse north. The trail then bends and passes several rock columns and various drop-offs. After another bend you will enter the final section and see the summit in the distance. The trail traverses across to the base of the peak and then gradually ascends to the summit.

6. Mt. Whitney- Mile 11.0- 14,497'

    Deciding When To Go

    Most people day hike the trail between July and September when the snow on the trail is minimal. There is really no perfect time to go. Snow can linger in shaded areas well into July and thunderstorms are a potential problem throughout the summer. If it will be your first time hiking in this kind of environment, pick a date in late July, August or early September. There is nothing you can do about the weather, just use good judgment on when to turn around if it gets bad and be prepared for a wide range of temperatures.

    • May-June: The winter snowpack slowly recedes. Expect snow on the ground above Lone Pine Lake through Memorial Day weekend, and snow on the switchbacks above Trail Camp through June. Nights are usually still below freezing. Winter-like storms are still possible. There was snow on the trail until after July 4th in 2011.

    • July-early September: The trail is usually snow free and the weather can be fair and pleasant. At elevations above Trail Camp, However, it is often cold and windy. Thunderstorms and lightning are a significant hazard. If thunderstorms are forecast, plan to leave the summit by noon. Be aware thunderstorms sometimes will occur early in the day. At the first sign of lightning, leave the summit area or exposed ridge tops.

    • Late September-October: Short days and cold temperatures make day hikes to the summit difficult. Storms may bring severe cold with high winds and snow deposits from a few inches to several feet. Thin snow may melt quickly, but deeper drifts may linger for the winter. Winter mountaineering equipment and skills are necessary for safe travel when snow is on the mountain.

    • November-April: Winter prevails, with deep snow and very cold temperatures. Winter storms may drop several feet of snow and have winds over 100 mph. The road to Whitney Portal is usually closed 8/3 miles from Lone Pine (at elevation 6,400 ft., about 3 miles from the trailhead) from mid-November to late April. Experienced winter mountaineers should be suitably equipped for extreme conditions and check avalanche conditions and weather forecasts


    If you want the moon up in the morning when you start your hike, pick a date several days after a full moon. If you would like to have the moon up after sunset, pick a date several days before a full moon. You can calculate moon almanac information for your date on the US Naval Observatory sun and moon data page.




    Travel Plans

    Air Travel
    There are no large commercial airports near Lone Pine. If you are looking for a scenic drive, Reno or Las Vegas are good choices. Most would advise avoiding the Los Angeles area airports due to traffic. If you must fly into the LA area, a mid AM arrival would be best. Rush hour (2pm-7pm) traffic can easily increase your drive time by an hour or more. Ontario is a good choice if you time it right.(traffic after 2pm going north on the 15) There are also small general aviation airports in Lone Pine, Independence, Bishop and Mammoth Lakes.

If bus and/or train is your only option, the Eastern Sierra Transit Authority is the sole provider of inter-regional public transportation for the entire Eastern Sierra Region. They operate several routes between in the Eastern Sierra. The  Yosemite Area Regional Transportation System provides bus service between Merced and Mammoth Lakes via Yosemite National Park when Tioga Pass is open. Greyhound provides service to Reno, Las Vegas, Los Angeles, San Bernardino, Merced and Mojave. Amtrak has train service to Victorville, Fresno and Reno and bus thruway service to Las Vegas, Mojave, Yosemite and Carson City.

    The Mt. Whitney Shuttle Service provides private transportation to and from  airports, bus stops , trailheads and other destination in the Eastern Sierra.  

     


    Where to Stay

    Campgrounds

    Most people prefer to camp at one of the higher elevation campgrounds for the acclimation benefits. The Inyo National Forest has over 80 campgrounds in the Eastern Sierra to choose from. None of the campgrounds near the Portal have showers, however there are 5 public showers at the Mt. Whitney Hostel for a small fee. The following are the highest campgrounds in the Eastern Sierra, and a few lower campgrounds that are near Mt. Whitney.

If you would like to stay in a motel at a higher elevation, the Mammoth Lakes area, Rock Creek Resort, Bishop Creek Resort, and Parchers Resort offer good options. Below are some of the more popular motels in the Lone Pine area:
    • The Mt. Whitney Hostel- Rooms sleep 4-8 people. You can reserve a room for your group or use as private room. $20.00 Per bed plus taxes. Each room has a bath and shower. There are public showers on the first floor. 760-876-0030

    Training

     Although most sections of the main trail are not very steep, you still gain over 6,000 feet on the way to the summit. The amount of conditioning you need depends on your current fitness level and experience with strenuous day hikes. If you have never really hiked before then prepare your body for the challenges that lie ahead and start out slowly. If you are a great swimmer and you think that you are in great condition and could easily hike for hours on end, you can be wrong. Hiking up and downhill on uneven terrain is a pretty specific fitness exercise that strains your body in ways that it may not be used to. Even if you are used to walking, strapping on a backpack and walking on rough terrain at higher altitudes will suddenly change your entire experience. Endurance is more important than speed when day hiking Mt. Whitney, so pace yourself! 

    Start Moving

    • Begin with shorter, less strenuous hikes and a light backpack. Nothing gets muscles ready for the trail better than the trail itself.
    • Gradually increase the length and elevation of your hikes and increase your backpack load. As you begin to strengthen your lower body and improve your endurance, switch to longer, more challenging hikes. Loading your backpack with the gear and weight you are most likely to carry will help you become familiar with conditions you will face. You should be able to complete a 17 mile or greater hike with at least 5000' of elevation gain without any problems prior to day hiking Mt. Whitney.
    • If you don't have mountains or hills in you area, increase your hike distances beyond 22 miles. Use the stairs at local stadiums or high-rise building to simulate vertical gain. Prior to day hiking Mt. Whitney you should be able to hike for 10+ hours without major problems. 
    • Try stair-steppers, elliptical trainers and climbing machines. These machines provide a great cardiovascular and strength training work out. They isolate your lower-body muscle groups and help build endurance.
    • Lift weights.A consistent, diversified weight-resistance program helps prepare muscle groups all over your body for the sudden jolt of full-time, all-day physical activity. Trained muscles are less susceptible to injury and strains.
    • Swim. A great aerobic workout, swimming is easy on the joints and good for the lungs and heart.

    Use the Resources Around You

    • Take the stairs whenever possible. Walking or running up and down them on a regular basis is terrific pre-trail training. 
    • Walk instead of driving. If you can perform certain routine chores by leaving your car keys in your pocket, do it. Walk to the library, the park or the store. Toss a weighted day pack on your back for a little extra benefit.
    • If you've got a bike, start pedaling. Cycling is an excellent way to condition your legs and increase endurance.
    • Find a local hiking group! The Outdoors Club and Meetup.com offer a wide range of great hiking opportunities all over the world. 

    Learn What Works For You

    Training also involves learning your gear and what works best for you on a hike. The day of the hike is not the time to break in the new boots, or try out your new water filter. Train with the same footwear, clothing and gear  you plan to use on the day of the hike. Your training hikes are a good time to figure out how you plan on carrying and treating your water. Pay attention to how much water you are drinking and what foods you like. If you plan on starting your Mt. Whitney Hike in the dark, start some training hikes in the dark. Learning all of theses things on your training hikes will make your day hike of Mt. Whitney a lot more fun.

    Clothing

    Layering your clothing is a tried-and-true way to ensure your comfort in the outdoors. The beauty of this simple concept is that it allows you to make quick adjustments based on your activity level and changes in the weather. Weather conditions can vary drastically from the trailhead to the summit. Be prepared for temperatures anywhere from 20°- 90°. Intense sun, strong winds, rain, hail, and even snow are possible anytime of year. Be sure to check the weather forecast before your hike so you can plan accordingly. While you are moving, wear the least amount of layers as possible to avoid sweating. When you stop for a break, put on additional layers to retain your body heat.


    Base Layer: Moisture Management

    Trapped inside your clothing, perspiration can leave you chilled or damp no matter how well your outer shell fends off rain and snow. Cotton is an example of a fabric that retains perspiration and can leave you vulnerable to unwanted chills. This isn't a problem when it is hot out, but on the Mt. Whitney trail you are likely to experience a wide range of temperatures.

    Base layers can be anything from briefs and sports bras to long underwear sets (tops and bottoms) to tights and sport shirts. What ever you choose, the material should be silk, wool or synthetic fabrics such as REI MTS®, Patagonia® Capilene®, Polartec® PowerDry® and CoolMax® polyester. Unlike cotton, these fabrics transport (or "wick") perspiration away from your skin, dispersing it on the outer surface where it can evaporate. The result: You stay drier even when you sweat, and your clothing dries faster afterward.

    Your Middle Layer: Insulation

    The insulating layer helps you retain heat by trapping air close to your body. Polyester fleece vests, jackets and tights are classic examples of insulation ideal for outdoor activities. They not only trap air but are also made with moisture-wicking fibers to help keep you dry. For most summer day hikes a light weight fleece jacket, and/or a thick long sleeve shirt is sufficient.

    Your Shell Layer: Weather Protection

    The shell (outer) layer protects you from wind, rain or snow. Shells range from pricey mountaineering jackets to simple windproof jackets, but most are designed to block precipitation and hold in your body heat while allowing water vapor to escape. This is an important piece when you're active, because if wind and water are allowed to penetrate to your inner layers, you begin to cool off. Furthermore, without proper ventilation, perspiration can't evaporate but instead condenses on the inside of your shell.

    If afternoon thunderstorms or rain showers are in the forecast, you may want to bring along rain pants. For most people convertible type pants/shorts are ideal in the summer. Side zippers are a big help. They allow you easily change between shorts and pants with out having to remove your boots.

    Head, Hands and Skin Protection

    Along with the above-mentioned clothing, it is recommended that you bring a shade hat, beanie, gloves, sunglasses, sunscreen, lip balm and insect repellent.

    Footwear

    Choosing the right footwear may be the most important decision you make as a hiker or backpacker. Spend some money on a good, comfortable boot or shoe. Try on lots of pairs and go with what feels best out of the box. The shoes or boots you choose must be comfortable, durable and protective, mile after mile. People hike the Mt. Whitney Trail in anything from tennis shoes to heavy-duty mountaineering boots. Choose footwear that you will be comfortable in for 12-18 hours on uneven terrain. Go to a reputable outdoor store and be properly fitted. Break in your footwear on actual hiking trails, not just around your home or office. You should not have to put up with spots that rub, blisters or tightness.

    Types of Shoes and Boots

    • Light hiking—These boots (and trail shoes) are designed principally for day hiking. They focus on light weight, flexibility, comfort and breathability. As a result, they are less supportive and durable than your other options.
    • Hiking and backpacking—These boots (and a few shoes) are designed for on- and off-trail hiking with light to moderate loads. They are more durable and supportive than lightweight hiking boots, but they are still intended primarily for short to moderate trips over easy to moderate terrain.
    • Extended backpacking and mountaineering—These boots are designed for on and off trail, multi day trips with moderate to heavy backpacking loads. Durable and supportive, they provide a high degree of ankle and foot protection. Some of these models are designed specifically for rough terrain with heavy backpacking loads. They offer the very best in durability, support and protection. Most are stiff enough to accept crampons for snow/ice travel.

    Socks

    A few good pairs of hiking or backpacking socks are essential. These socks are designed to provide reliable cushioning and wick moisture away from the skin. Many models have extra padding built into high-impact areas like the heel and the ball of the foot for maximum comfort. Carrying an extra pair of socks is highly recommended. Socks should be made of wool or a synthetic wicking material. Cotton socks will make your hike miserable. 







    Gear

    The following is a list of basic gear you will need to day hike Mt. Whitney during average summer conditions. During winter, spring and fall, crampons, ice axe, helmet, snowshoes and winter mountaineering skills are essential. Be sure to check with the Whitney Portal Store Message Board or WhitneyZone.com for recent trip reports and contact the Mt. Whitney Ranger Station prior to your trip for current trail conditions. Just remember you will have to carry all this stuff 22 miles, so keep it as light as possible.

    • Backpack- Packs with capacities around 30 liters are a popular choice for a typical day hike. Make sure it can comfortably carry all your gear, food, water and extra clothing.
    • Hydration system or plastic bottles for 2 or more liters of water.
    • Headlamp- A basic LED headlamp will be fine. Use high quality lithium batteries and start your hike with a fresh pair. Bringing an extra set is a good idea.
    • Map- The Tom Harrison Mt. Whitney Zone map is excellent, or print your own and carry it in a plastic baggie to protect it from moisture. You should familiarize yourself with the map and points along the trail prior to your hike. When you stop for a break or when you see a landmark along the way, pull out your map and figure out where you are and where you are headed next. If clouds roll in, visibility can be reduced to a few feet.
    • Compass and or a GPS- Navigation is not difficult in good weather on the Mt. Whitney Trail, however be prepared for bad conditions. Use lithium batteries in your GPS and start with a fresh pair. You should learn to use these items on your training hikes!
    • First Aid Kit- Band aids, mole skin, tape, Aspirin, etc. You wont be preforming open-heart surgery along the trail, keep it simple.
    • Reflective blanket- For emergency shelter. Get the lightest one you can find. 
    • Waterproof matches or fire starter- Though fires aren't allowed in the Mt. Whitney Zone, these items should be a prat of your first aid kit for all hikes.
    • Small Knife- Keep it simple, the lighter and smaller the better. You don't need a 51 piece multi-tool for a day hike.
    • Trekking Poles- Help to "save" the knees and for extra help in balancing on tricky terrain and stream crossing.

    Water

    Staying hydrated while acclimating, and during the hike is extremely important. The amount that you need depends on several factors including temperature, humidity, body mass, pack weight, fitness level and start time. Most people will consume between 3-6 liters of water day hiking Mt. Whitney. Many people add an electrolyte sports drink mix to their water or bringing a liter of Gatorade along to help stay hydrated . Water is available at many places along the main trail up to just beyond Trail Camp. It is a good idea to top off your water before starting the 97 switchbacks because it is about 10 miles round trip from this point. The stream flowing into the trail camp pond is an excellent source of clean water. For most people, there is no need to carry more than 2 liters of water at a time. Water is likely the heaviest thing you will be carrying, so learning how much is right for you is very important.

    Some thought should be given to how you are going to carry your water. Some people prefer using "Camel Back" type reservoirs, while others prefer water bottles. Water bottles tend to be easier to refill in streams and lakes because you can just submerge the bottle and fill it up. It is inconvenient to remove a reservoir system from a backpack and fill it in a stream or lake. This is not a problem if you plan on using a pump type filter. Either way you plan on carrying your water, you should practice treating water, and refilling your container on your training hikes.

    There is much debate on filtering and treating water in the Sierras. Most people filter or treat their water with Iodine just to be safe, while many seasoned mountaineers drink untreated water throughout the Sierras. See Bob Rockwells Reliable Water Sources Along the Mt. Whitney Trail for information on various water sources along the trail. When day hiking Mt. Whitney, it is easiest to use iodine tablets or don't treat at all. Filters are expensive, bulky and have many parts. Its one less thing to carry in your pack.

    Food and Supplies

    On the Trail

    The general trend to follow is, the harder and longer you are hiking, the more simple carbs you need to be eating. This goes for any endurance activity. The higher the intensity, the larger % you are burning energy from your muscle glycogen stores. When these run out, you will hit the "wall", as well known in marathon runs for example. You simply have to slow down when burning energy from fat. So the key is to stop those glycogen reserves from running out. How do we do this? Carbs. Simple carbs. Sugar. Bread. These substances (foods with high Glycemic Index ratings) are the best for the same reason they are looked down upon when eating while sedentary: They will be absorbed into the blood stream very quickly. Carbs with fiber take longer to breakdown (and may cause stomach issues), and fat and protein have to go through other chemical reactions before getting into form for usable energy. The day of the hike is not the time to start a diet! 

    Common foods brought on a day hike include various "power" bars, bagels, trail mix, peanut butter and jelly sandwiches, fruit, cookies, candy and energy gels. During your training hikes you should learn what works for you. It is important to snack often through out the day. Remember you will be on the trail for 12-18 hours so plan accordingly.

    Restaurants, Markets and Supplies

    Restaurants in Lone Pine include Bonanza Mexican Restaurant, Pizza Factory, The High Sierra Cafe (24 hours), Mount Whitney Restaurant, Seasons, Margie's Merry Go Round, Carls Jr and Mc Donald's.

    The Whitney Portal Store serves great food including huge pancakes, bacon, sausage, eggs, hot dogs, burgers, french fries and chicken sandwiches. Aside from the grill, the store has cold beverages (including beer), energy bars, and snacks. The store also sells basic supplies for hiking, camping, fishing and also rents bear canisters. They are open until 8 or 9pm in the summer.

    The closest supermarket is Joseph's Bi-Rite Market in Lone Pine. There are also several liquor stores in town.

    You can find camping, hiking, mountaineering and fishing supplies at Lone Pine Sporting Goods, Elevation, Sierra Adventure Essentials and True Value Hardware.

    Preparing for High Altitude

    In higher altitudes, the oxygen level of the air is lower, making your body work less efficiently. These are some important facts on Higher Altitude Hiking:

    • People can feel the effects of higher altitudes as low as 6000 feet above sea level, however most people can tolerate altitudes of 8000 feet with out incident. 
    • People differ in their tolerance for high altitude conditions and how their bodies react to the changes in air pressure and oxygen level.
    • There is no relationship between your overall physical fitness level and your tolerance to high altitudes. Furthermore, an improved fitness level might cause you to push harder and over exert your body, which is one of the main causes of AMS.

    It is important for most people to acclimatize at high altitude for at least 24 hours before attempting to day hike Mt. Whitney. Whitney Portal (8,360') is not necessarily the best place to acclimatize, but it is very convenient for people who want to hang around the Whitney Portal Store and the trailhead. At Whitney Portal you can also do a warm-up hike up to Line Pine or Meysan Lake. Horseshoe Meadows (10,000 feet), Onion Valley (9,200 feet) and the Tioga Pass area of Yosemite offer higher elevation camping and excellent warm up hike opportunities. See Where to Stay for more information. 

    For most people, a nights sleep at around 10,000' and some type of warm up hike at a moderate altitude is sufficient. If you are more sensitive to altitude, or unsure of how you will react to altitude you may want to plan more time to acclimate or consider taking a medication such as Diamox to help adjust. Regardless of your plan, you should drink plenty of water as you acclimatize to avoid dehydration. The Eastern Sierra offers endless hiking and sightseeing opportunities. If you have the time, spend a few days exploring the area! See Warm Up Hikes for ideas on acclimating.

    Factors that Influence Acute Mountain Sickness

    These are the factors that are related to Acute Mountain Sickness and the severity of your condition:

    • Altitude: of course the main factor in getting AMS is altitude.
    • Rate of Ascent: the speed in which you gain altitude. The faster you ascend the less chance you give your body to acclimatize and adjust to the higher altitude conditions.
    • Degree of Exertion: the more you physically exert your body the more likely you are to suffer from AMS. It is important to pace yourself. There is no reason to race to the peak. Keep a good steady pace and take short breaks.
    • Hydration: the more dehydrated you are the more likely you are to suffer from AMS.

    Preventing AMS

    Preventing AMS is easier than treating it. These are the guidelines for preventing AMS:

    • Hike slowly but steadily to higher altitudes. Likewise take slow, deep and deliberate breaths.
    • If you must drive directly to altitudes 10,000 feet or higher, then take at least a period of 24 hours of rest.
    • Keep yourself well hydrated (3-4 liters per day) and check your urine for clarity.
    • Eat a diet high in carbohydrates.
    • Do not over exert yourself and keep a steady walking rhythm without any large peaks in physical effort.
    • Regularly check yourself and members of your group for symptoms of AMS, which will be described below.
     Medications
    Diamox is the most tried and tested drug for altitude sickness prevention and treatment. It seems to works by increasing the amount of alkali (bicarbonate) excreted in the urine, making the blood more acidic. Acidifying the blood drives the ventilation, which is the cornerstone of acclimatisation.  For prevention, 125 to 250mg twice daily starting one or two days before and continuing for three days once the highest altitude is reached, is effective. Side effects include: an uncomfortable tingling of the fingers, toes and face carbonated drinks tasting flat; excessive urination; and rarely, blurring of vision. Most people recommend trying the medication at home or on a training hike so you can determine benefits or disadvantages of using the medication prior to your Mt. Whitney day hike. Consult with your doctor for a prescription and  more detailed information on this drug.

    Symptoms of AMS

    You should periodically analyze yourself and members of your group for symptoms of AMS. Most of them can happen to you independently and are not necessarily signals of AMS. If you suffer from one or more of them you may want to descend to a lower elevation. Minor headaches are very common, and often relieved with ibuprofen or asprin.

    • Headaches are the most common symptom. If you feel a headache after a period of exertion take a rest, breath deeply and/or take an aspirin and wait for the headache to disappear. Stop ascending if the headache persists even after a nights rest and medication and is moderate to sever. If the headache is severe and persists it is a clear sign that something is wrong.
    • Physical exhaustion and loss of co-ordination even after proper food, fluid intake and rest.
    • Insomnia is another common high altitude ailment. In higher altitudes it is important to breath deeply and steadily.
    • Loss of appetite, reduced urine output and especially nausea are all potential signs of AMS.


    Plan When to Leave

    The best time to leave on a day hike depends on a number of factors, including:

    • Time of year (amount of daylight and vulnerability to afternoon storms)
    • Return time (do you want to be back at the Portal Store for a burger before it closes?)
    • Acclimation
    • Sleep time required before hike
    • Size and experience of group
    • Where you want to be at sunrise (like Trail Crest ect.)

    As a rule of thumb, you want to plan to be at the summit no later than noon. That gives you some extra time to play with in case your trip up takes longer than expected (most likely) and hopefully will give you enough time to avoid any afternoon storms that may materialize (especially in July and August). For most people that means leaving the Portal by 4 AM. The 12pm rule is just a guideline. There is nothing wrong with reaching the summit at 2 or 3PM if the weather is clear. Likewise, thunderstorms can develop well before 12p. 

     If the forecast is calling for thunderstorms, you are in a large group, and/or you are a slow hiker you may want to start earlier. This is a good idea for a few reasons:

    • Thunderstorms can develop as early at 10 AM.
    • It is much cooler during the early AM hours, therefore requiring less water.
    • Most people don’t sleep well the night before due to anxiety and elevation. If you can't sleep get up and go.
    • Most people prefer to start in the dark while they are fresh and alert rather than coming down in the dark while you are physically and mentally exhausted.

    Have a Plan Before You Start

    This is easier said than done. Most people are just concerned with getting to the top and don't plan ahead for possible problems.  A lot of things can happen on the Mt. Whitney trail, especially with a large group. It is better to have an agreement up front on what everybody's roles and responsibilities are. Be sure to read the What Can Go Wrong Section on Whitneyzone.com. Some basic questions to ask are:

    • Does the group plan on staying together to a certain point or the entire hike?
    • What do we do if we get separated?
    • What do we do if somebody is lagging behind the rest of the group?
    • What is the turnaround time for our ascent?
    • What do we do if somebody gets injured or shows symptoms of AMS?


    Weather

    Unpredictable weather is an inherent risk in wilderness travel, so hope for the best, prepare for the worst. Sunshine, wind, rain, hail, snow, ice and lightning are all possible anytime of year on Mt. Whitney.  Many summer storms are accompanied by high winds, hail and lightning, particularly at the higher elevations. Pay attention to developments in the sky. The shapes and movements of clouds typically foreshadow changes in the weather such as the arrival of thunderstorms. 

    •  Sunshine-  At higher elevations, people can be more susceptible to the rays of the sun, since there is less atmosphere above to filter out the harmful rays. The effects can also be intensified by reflections off of snow. Be sure to have a wide-brimmed hat and cover up as much of your body as possible while hiking in daylight. Apply sunscreen to the remaining parts of your body, including your ears and around your nose.

    • Snow, Ice and Hail- Snow and ice can be a problem on the 97 switchbacks and other portions of the main trail, particularly in the cables area. Extra care should be taken on any areas covered in snow or ice. Mountaineering gear and skills may be necessary during early summer, spring, fall and winter. Check the Whitney Portal Store or Whitneyzone.com message boards for recent trip reports and contact the Mt. Whitney Ranger Station prior to your trip for up to date trail conditions.

    • Lightning- You should not hike above Trail Crest if thunderstorms are developing. Thunderstorms can develop quickly in the mountains and the upper trail is very exposed to lightning. If you see swelling clouds you should descend below Trail Crest immediately.  They are the first stage of thunderstorm growth and can become dangerous in a matter of minutes. These white or gray clouds with flat bases are taller than they are wide. The earlier in the day that swelling clouds appear, the greater the probability that they will develop into thunderstorms. Their growth can usually be seen with the naked eye, and the faster the swelling clouds are growing the more threatening the situation. Lightning strikes can send an electrical current radiating through the ground over a large area. This "ground current" is usually the lethal force in storm-related fatalities.

      Never take an electrical storm casually. If lightning threatens while you are on the trail, take immediate action:

      • Move away from a tall, solitary tree or any lone, tall object. Isolated high-rise objects are likely strike points for lightning.
      • Descend from ridgelines or peaks. Lightning tends to strike prominent topographic features. In threatening weather, move away from high points and exposed areas. Head for lower ground.
      • Stay away from water.
      • Separate yourself from metal or graphite objects, including external-frame packs, ice axes, trekking poles and crampons.
      • Keep out of shallow caves or overhangs. Lightning's current easily jumps across gaps and could jolt a person standing in the mouth of a cave.
      • Insulate yourself from the ground; sit on an internal-frame pack or sleeping pad. Or crouch on the ground with your feet close together. If a ground current reaches you, it most likely will travel only through your feet. Do not lie down (since it expands your contact with the ground).
      • Have members in your party spread out by at least 25 feet, farther if possible.
      • A strike victim can be revived by CPR.
      • Where is the best place to be? Within a group of trees of roughly uniform height in a low-lying area or, as a second option, in a low spot of an open meadow.
