Midway Geyser Basin - Yellowstone NP
There are so many places in Yellowstone National Park where you can see geothermal areas in different colors and sizes. The Midway Geyser Basin has is the largest in Yellowstone, but since you are on the same level, you are not able to see the whole area. Some people held up a tripod with an attached Camera, that way you get a better picture, but you don't see it. We saw people hiking on the little mountain behind the basin, I believe you get a great view from there. The hike's name is "picture hill".
