Explore Midway Geyser Basin with Gaper Guide
Midway Geyser Basin is relatively small, but if you take the walkway around it, there are two really impressive features there that are worth the stop. Probably the most iconic of Yellowstone’s hot springs, and certainly the largest, Grand Prismatic Spring is 370 feet in diameter and more than 121 feet deep. Walking around it is an otherworldly experience as the steam envelops you and the oranges, whites, greens and reds of the feature blend together. Excelsior Geyser erupts from a huge crater 200 x 300 feet with a consistent flow of more than 4,000 gallons of water per minute into the Firehole River. This stop is not to be missed!
