Yellowstone’s Mammoth Hot Springs is one of Yellowstone National Park’s most popular sightseeing tour attractions. Here you can see dozens and dozens of hot springs, ranging in size and color, often with fascinating mineral deposits.
Mammoth is one of the best places to see evidence that Yellowstone is indeed the caldera of a giant volcano. As a result of the constant geothermal activity under Mammoth, the springs are constantly changing, with old ones shutting down, and new ones opening up. Sometimes you’ll find parts of the boardwalk that takes you through Mammoth covered over by new formations!
Mammoth can be conveniently accessed from Gardiner, Montana. It is opened almost the entire year, with short closures in the Fall starting in November, and the Spring starting in March. Yellowstone’s winter is one of the best times to visit this area of the park, where you’ll see the hot springs continually steaming, and a heard of elk descend on Mammoth, and hang out in easy view of tourists.
