Snow Pass Trail 6750' to 7450'
4.2 miles, easiest to most difficult 700 feet elevation gain/loss
The Snow Pass Trail leaves the west side of Mammoth-Norris snow vehicle road .4 miles south of the Upper Terrace parking area. There is also a short connector trail from the upper end of the Upper Terrace Loop. The trail ascends 700 feet in 1.5 miles through a series of steep grades along an old wagon road to Snow Pass. Good views of the surrounding country are frequent. From Snow Pass the trail continues .5 miles over rolling terrain to a trail junction at which the ski route turns left (south) and follows Glen Creek over fairly level terrain for 2.2 miles, returning to the snow vehicle road just south of Rustic Falls. The other trails leaving from the junction lead into wilderness country; check at the Ranger Station before attempting to ski them.

Bunsen Peak Trail 6240' to 7360'
6 miles, easiest to most difficult, 1120 feet elevation gain/loss
This trail begins on the Mammoth-Norris snow vehicle road just south of Rustic Falls and across from the upper end of the Snow Pass Trail. .The upper 3 miles are mostly level and suitable for all levels of skiing ability. On the northeast side of Bunsen Peak, the road becomes steep and winding, dropping 960 feet in 2.5 miles to Glen Creek. CAUTION: some curves have steep drop-offs and can be hazardous when icy. From Glen Creek the trail climbs .5 miles to a plowed road in an employee housing area .8 miles below the Upper Terrace parking area and 1.3 miles above Mammoth. This trail provides fine views of the Gallatin Mountains and the Gardner River Canyon.

Indian Creek Loop 7300' to 7420'
2.5 miles, easiest to more difficult, 120 feet elevation gain/loss
This trail begins at the Indian Creek Hut and follows the campground road through the camp ground and out onto the Bighorn Pass Trail. The Indian Creek Loop veers off to the left (south) about a half mile west of the campground and follows a power line corridor over rolling terrain for 3/4 mile. The trail then descends and follows Obsidian Creek north, back to the hut. This trail provides some good views of the Gallatin Range.

Bighorn Loop 7300' to 7620'
5.5 miles, easiest to more difficult, 320 elevation feet elevation gain/loss
The trail begins at the Indian Creek Hut and coincides with the Indian Creek loop for the first mile. It then continues west, making a loop through rolling terrain with outstanding views of the Gallatin Mountains, Gardners Hole and the surrounding country. Bunsen Peak, elevation 8564, is about 3 miles NNE. After completing the loop, return to the Indian Creek Hut by the same route.

Sheepeater Trail 7260' to 7320'
5 miles, easiest, 60 feet elevation gain/loss
Beginning at the Indian Creek Warming Hut, ski along the snow vehicle road .5 miles north to Sheepeater Cliffs picnic area. The trail skirts the east side of Swan Lake Flats through interspersed forest and meadow with views of the Gallatin Range and the Gardner River Canyon. The trail connects with the Bunsen Peak Trail and continues approximately 1.6 miles west to the Mammoth-Norris snow vehicle road.

Upper Terrace loop Trail 6570' to 6780'
1.5 miles, more difficult to easiest, 200 feet elevation gain/loss
This loop begins at the Upper Terrace parking area. The trail is easiest if skied beginning to the left (clockwise). A moderate climb leads to views of hot springs, terraces, 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 in the Terrace area.
