Mammoth Hot Springs is one of Yellowstone National Park’s most stunning geothermal attractions. Its spring water comes from the Norris Geyser Basin, with temperatures reaching 77°C (170°F).
Algae in the water create shades of brown, orange, red, and green, forming a natural rainbow as the water flows down the terraces.
Walking along these terraces gives us a front-row seat to nature’s power. From the colorful formations to the rush of hot water, it’s a visual and sensory experience that is hard to forget. Families, photographers, and nature lovers alike will find this spot magical.

Getting to Know Mammoth Hot Springs
Located in Yellowstone’s northwest, Mammoth Hot Springs is also home to the park’s administrative headquarters. During spring, elk gather near the Mammoth Hotel lawns, creating excellent wildlife viewing opportunities.
The terraces are divided into Upper and Lower sections. The Upper Terrace has scenic overlooks and short walking paths, while the Lower Terrace allows closer interaction with the intricate limestone formations. Each area offers a unique perspective for photography and hiking.
The Changing Landscape
In 2002, an earthquake caused many of the hot springs to stop flowing. Large numbers of microorganisms died, turning some terraces pale white. Despite this, the terraces remain impressive, showing Yellowstone’s dynamic geothermal system in action.
