Grand PRISMATIC HOT SPRING

Grand Prismatic is the largest hot spring in North America. Bright bands of yellow, orange, and green accent the deep deep blue waters creating one of the most magnificent sights in the world.  You have to see it to believe it

Firehole River

The Firehole River is a great place to take a load off on the way back from a long hike in Yellowstone. Hot water flows from geothermal fissures into the running river, creating an intoxicating combination of hot and cold water. 

The Firehole River is a favorite swimming hole for many.
