Mammoth Hot Springs Professional Reviews and Guides

"While many of Yellowstone’s most famous hydrothermal areas wow audiences with their dramatic antics and predictable, instantly gratifying performances, Mammoth’s mercurial hot-spring terraces are impressive more for their important place in the history of the park and their long-term natural development. A network of boardwalks provides numerous options for exploring the most accessible thermal area in the northern half of the park.

At least some portion of the terraces can be explored year-round. When boardwalks are iced over in winter, the fringes of the thermal area are fascinating to explore via skis or snowshoes. There is no shade on the boardwalks, so bring plenty of water and sun protection."

"About an 18-mile drive along a high road between Lava Creek Canyon and Blacktail Deer Plateau. Scenic overviews are beautiful, though not dramatic."

"This hike is a series of walkway and boardwalk loops. They lead through magnificent travertine terraces formed by mineral laden hot water, limestone and carbon dioxide. The many colors of these terraces are from living bacteria and algae. These colors change at different temperatures.

White and yellow are the hottest. As the water cools, brown, green and orange algae take hold. The mineral formations are shaped by flowing water from the springs and ground slope. These landscapes are in constant evolving motion. If you have an opportunity to visit in the winter, you will witness these hot springs at their best."

This area has changed alot since I was young. Most of the springs are currently dry, which means less of the beautiful colors, but you still get to see all of the wonderful rock formations. Choose your route carefully, the boardwalk weaves around the springs and bad planning will have you walking uphill more than necessary. The smell of sulphur is not nearly as overwhelming here as it is at the geysers and mudpots. Be sure to check out this cute town before you leave!

The trail was very well-maintained but also quite crowded. Lots of people on this one! We missed the solitude that we've grown accustomed to on the other hiking trails. The most beautiful feature along the trail was Palette Spring (very colorful!). However, we were saddened to see that many of the travertine cascades, such as Minerva Terrace and Jupiter & Mound Terraces, were drying up (or already dried up). We hope that these formations can become "revived" again in the future. While in the area, the Upper Terrace Drive is a must-see. There are several interesting & beautiful formations such as Angel Terrace and Orange Spring Mound.
