The Upper Terrace Loop Ski Trail is a groomed 1.5 mile (2.4 km) loop that ranges from easy to more difficult due to a steep downhill section if traveled to the right (counter-clockwise) from the trailhead.
This loop begins at the Upper Terrace parking area. It is easiest if skied beginning to the left (clockwise). A moderate climb leads to views of hot springs, terraces, the Mammoth Hot Springs Historic District, and the surrounding mountains. At the top of the climb, a trail veers off to the southwest, which connects with the Snow Pass Trail. The Terrace Loop Trail descends past more hot springs before completing the circuit. Since snow depths here are less than in the mountains above, wintering elk and deer are occasionally sighted.
Notes: Bison and elk frequent this trail. Federal regulations require you to stay at least 100 yards (91 m) away from bears and wolves, and at least 25 yards (23 m) away from bison and all other wild animals.
Caution: Stay on boardwalks and designated ski trails. The ground is unstable in hydrothermal areas. Short-cutting or cross-country travel can damage the fragile hydrothermal features along the trail and is prohibited.

This groomed ski trail follows a paved road for the entire 1.5 mile loop. The section to the left of the gate includes a steep uphill/downhill, and some sections do not hold snow due to thermal activity. For an easier out and back ski, go to the right at the gate and turn around at Orange Spring Mound to avoid the steep downhill section beyond. Service dogs allowed.
