Yellowstone National Park
This place is the most beautiful Geyser National Park in North America. Though there is a lot of Asians who are rude when you try to take a photo, but Old Faithful was amazing, but a little of time. They have some paths made of recycled bottles. When I was there Steamboat had it's first major eruption since 2005. Yes, Yellowstone gets a lot of earthquakes, but you never feel them.
