Mammoth Hot Springs, Yellowstone National Park
(4.3/5 based on 1,300+ reviews on the web)
A large complex of springs in Yellowstone National Park, Mammoth Hot Springs, was created over thousands of years by hot water from the springs cooling and depositing calcium carbonate. Typically a bleached-white hue, the dramatic terraced sections flow with water originating from rain and snowmelt, causing a frozen cascade effect (though the water that forms this area is extremely hot). The flow of water depends on the environment at any given time, but you can walk the boardwalks along the lower and upper terraces, observing the scenery and wildlife. Put Mammoth Hot Springs at the forefront of your travel plans using our Yellowstone National Park tour planner.

  • This is a one of a kind earth formation that was just incredible to see in person. It's a little overwhelming to know where to go because there are multiple paths and limited parking. I found parking at one of the upper springs so we walked around that one. My wife went to the lower spring on her way to the bathroom and said it was much cooler than the upper one.
  • On the northern end of the park, this site is a one of a kind inside Yellowstone. There are many walkways to view everything from many angles. A must stop.
  • What happen to the hot springs? Was here 25 years ago and 80% of the hot springs were active and "colored" by bacteria and minerals. Today maybe 20% is active and the rest is white. Shows how the underground pluming has changed over time. During August get there early, by mid-day it will be very crowded.
  • I felt amazing that I saw nature's beauty from an entirely different perspective. Give it a shot, I am sure you would not be less surprised to see things in Yellowstone: Geysers and hot springs are awesome!
  • Another place you have to stop. Get out and walk around. Sure you can see plenty from the road but that just isn't enough. After your walk and pictures go get a huckleberry ice cream down the road. Or better yet, do it before. Hopefully your ice cream won't melt too fast!
