Ski Trails and Routes for Mammoth Hot Springs in Yellowstone: 

Upper Terrace Loop Ski Trail

Mammoth Hot Springs are the largest travertine terraces in the world. Mammoth is called “Mammoth”, due to its enormous size. The Upper Terrace Loop of Mammoth circles the top portion of this unique geological feature. During the summer months, the loop is a one-way drive for visitors. For the winter season in Yellowstone, the Upper Terrace Loop is turned into a great cross-country ski route. 

The trail starts at the parking lot at the Upper Terraces above Mammoth. We recommended taking the trail to the left and skiing the loop in a clockwise direction. The first major spring is Angel Terrace. Angel Terrace has become very active in recent months. As of December 2020, Angel Terrace is one of the most active springs in Mammoth. The first portion of the trail is a moderate climb. As you ascend, look for the spur trail to the Snow Pass Ski Trail. Continue past the intersection of Snow Pass and onto Orange Mound Spring. Orange Mound Spring is a huge hot spring formation that is only visible on skis or snowshoes in the winter. After Orange Mound Spring, the trail descends to the north and offers great views of the town of Mammoth or Fort Yellowstone. The town of Mammoth Hot Springs is actually an old military base, known as Fort Yellowstone. Continue along the ski track and back to the starting point. If feeling motivated, take your skis off and walk down to the overlook of Canary Springs. 

Upper Terrace Loop Ski Trail Info:
1.5 miles (2.4 KM)
Rated: Easiest to Difficult

Notes about Winter Travel

  • Yellowstone’s north entrance by Gardiner, Montana is the best way to access the ski trails at Mammoth Hot Springs. The north entrance is open year-round!!! The official winter season typically starts in December 15 and ends in March (depending on snow levels).
  • Winter weather in Yellowstone is extreme. Temperatures can vary from just above freezing (32 F) to nighttime lows of -30 F. Please be prepared and have plenty of layers.
  • Due to the altitude of the park and winter weather of Yellowstone, it’s very important to stay well hydrated. Make sure to bring along plenty of water and snacks while skiing. Skiing can burn lots of calories that need to be replenished.
