Create an itinerary including Mammoth Hot Springs
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.

  • It was definitely worth the stop and walk. Even though it was primarily frozen at the time, it was still stunning because of the geological formations and variations of colors.

  • Beautiful place to be in. Place can be seen by boardwalks. Few places there are steps and quite steep but the sites are worth taking that effort. One should not miss the devil's thumb during the visit. One can go to upper gyser by car too... Just be aware that there are narrow lanes though.
  • Even in early spring the hot springs were active, I was hoping for a bit more but it is quite nice and certainly a first time for us. The climb to the top is also beautiful (though exhausting) where you can see other colorful springs. You can also watch Bisons roaming about freely through the hot springs where you are not allowed to :) Note: if you do not want to climb you can drive a little further to another landing at top.
