Midway Geyser Basin is one of the most famous, and by nature, the most crowded of all Yellowstone’s thermal areas. It contains the biggest and prettiest spring in the park called Grand Prismatic Spring. The whole trail is on easy boardwalk with very minimal elevation change. The trail starts out by crossing a bridge over the Firehole River.
You can see the huge amounts of water coming from Excelsior Geyser as it pours water into the river.
Excelsior Geyser is a huge crater full of water. It dumps 4000 gallons of water into the river per minute. The day we were there it was so steamy I was not able to get any good pictures. It has very pretty blue water and is very large.
Next up is the second most famous thermal feature in Yellowstone behind Old Faithful. Grand Prismatic Spring is absolutely gorgeous. Even with the steamy conditions you can still see the many colors in the area. The spring is the largest in Yellowstone and is 370 feet wide and 120 feet deep.
Here are a couple pictures taken from a nearby hill giving you a good idea of the scale of this pool.
After Grand Prismatic you will pass a couple much smaller hot springs that are the last features of the hike.
This area is really pretty and Grand Prismatic is amazing to see but it can also be very crowded with inconsiderate people. I still recommend everyone visit at least once.
