Mammoth Hot Springs, Yellowstone National Park

4.5
#4 of 82 in Parks in Yellowstone National Park
Hot Spring · Nature / Park
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.

    These terraces are amazing! And each can grow by as much as 6' a year. The boardwalks allow great, close-up access to admire the beauty. The upper terraces drive is a good way to visit if walking a lot won't work for you. The elk down by the hotel we're also great to see.
