Yellowstone National Park is located in Wyoming (and a little bit in Montana and Idaho). Directly to the south of it is Grand Teton National Park. Yellowstone is best known for the geysers (Old Faithful is just the best known of dozens) and other thermal features as well as it's bison herds.
My favorite part of the park is the Upper Geyser Basin, home to Old Faithful, Grotto Geyser, and Riverside Geyser. It is incredible the amount of thermal activity there is there and you can't find anything like it anywhere else in the United States. My next favorite is Grand Prismatic Spring. It is a large hot spring with blues, greens, yellows, and oranges. I hiked up to the hills above it and got a great view.
