The Mammoth Hot Springs Terraces are a stunning collection of cascading limestone formations created by thermal water flowing over the landscape. Their colors and constantly changing shapes make them one of Yellowstone’s most unique geothermal features.

Hiking

Wooden walkways guide visitors through the fascinating, ever-changing geothermal area. Hot, lime- and mineral-rich water bubbles to the surface and, as it flows down the slopes, deposits lime and minerals, creating the distinctive, constantly growing terraces in various colors.

Mammoth Terraces Trail

The Mammoth Terraces Trail offers a truly unique hiking experience through Yellowstone's geologically active Mammoth Hot Springs. You'll wander along boardwalks and paved paths, immersing yourself in an otherworldly landscape of travertine formations, often likened to "inside-out caves." The terraces shimmer with vibrant hues of white, orange, and yellow, thanks to the mineral-rich waters, and you'll encounter notable landmarks like the impressive Liberty Cap and the ever-changing Palette Spring, all while steam curls around you.

This easy 3.0-mile (4.8 km) route, with 463 feet (141 metres) of elevation gain, typically takes around 1 hour and 24 minutes to complete, making it an excellent choice for beginners or families. While much of the trail is gentle, be prepared for some steeper sections as you ascend to the top of the Main Terrace. Always stay on the designated paths due to the active geothermal features, and consider an early start to enjoy the unique atmosphere with fewer crowds.

The Mammoth Terraces are renowned for having the world's best display of travertine deposits, a testament to the park's dynamic geothermal activity. The springs and formations are constantly evolving, meaning each visit offers a slightly different perspective on this surreal wonderland. Views from higher points can extend towards the Yellowstone River canyon, and you might even spot wildlife like elk, adding another layer to this memorable natural feature.
