Transportation

First and most importantly, getting to Boulder from Denver International Airport, there are two options:

1. RTD Bus (recommended option):

The RTD bus line "AB1" runs frequently from Denver International Airport to the city of Boulder - follow the signs to public transportation, take the long escalator down to the train and bus terminal from the south end of the terminal.  Click here for the bus schedule.  The one-way fare is $10; you must have exact change, or you can buy a ticket using one of the RTD machines in the bus loading area, or use the RTD app.  You should ride to the "Broadway/Euclid" stop, which is a 5-10 minute walk from Kittredge Central.

(There is also a train stop at Denver Airport, but that will take you to Denver Union Station, and there is no train connection from Denver to Boulder currently so you'll have to take a bus from Denver anyway.  Just take the AB1 bus.)

2. Airport Shuttle:

Eight Black Airport Shuttle (formerly Green Ride) offers door-to-door transport to and from the airport.  Visit their website for more details and to make a reservation.

Once you are here, for getting around the city of Boulder, there are several bus lines that run frequently.  See this page for a brief guide.  For convenient travel to the city of Denver, the Flatiron Flyer (FF) bus service is a good option - route FF1 runs from downtown Boulder to downtown Denver.  If you need a car for a few hours, eGo CarShare or ZipCar are both available on the CU campus.

If you're interested in getting around by bicycle instead, Boulder BCycle is a bike-sharing program with several stations on and around campus.   You may also be able to rent a bicycle from one of the many local outdoor supply companies; try REI or Christy Sports.  You'll also find Lime E-scooters available around Boulder, including on campus.

Parking

TASI students can purchase a month long parking permit by calling Parking at (303) 735-7275; ask for the lot closest to Kittredge Central, probably lot 308. The price would be around $60 for the month.  The parking office is open M-F; if you arrive over the weekend, purchase a short-term pass by following the instructions at https://www.colorado.edu/pts/short-term-parking/dailyweekly-parking.

In Boulder

The University of Colorado Boulder campus is located in Boulder, Colorado, nestled at the foot of the Rocky Mountains at a height of 5400 feet (1650 m) above sea level.  The weather during June is typically very pleasant, with a temperature range of 55°F to 85°F (13°C to 29°C) during the day and low humidity.  Thunderstorms in the afternoon are common (but usually very brief) - you may want to bring an umbrella.  Temperatures can be significantly lower at night, so you should bring a sweater or jacket.

There are many opportunities for outdoor recreation in the Boulder area, including a number of hiking trails.  Note that hiking in the mountains requires a good pair of hiking shoes and warm clothing, as there will be snow on the hiking trails even in June at higher elevations.  There are also many cultural activities in Boulder and more in Denver.

For more information on hiking in the Boulder area, see the Hiking Guide.  If you're interested in bike rides, Jim Cline put together a nice guide as part of his TASI 2018 lecture notes on early universe cosmology (see appendix A.)  Finally, for a list of places to eat and drink and other things to do in Boulder, see the Local Guide (compiled by CU's high-energy theory grad students.)
