Sheepeater Ski Trail

Q: Is it safe to go alone?

Mostly yes if you follow protocol. Bison and elk frequent this area—stay 25+ yards away, make constant noise. Federal law requires 100+ yards from bears/wolves. No cell service; carry emergency whistle, map, and compass. If you're nervous about solo wildlife, bring a partner.

Q: What gear do I actually need?

Winter ski or snowshoe setup, insulated boots, minimum 2+ insulating layers, wind-resistant parka, hat, goggles, sunscreen, 2L water, hand/toe warmers, emergency whistle, map, compass. Trekking poles help. Winter gear is not optional.

Q: How long does this take?

2–3 hours per NPS estimate. Depends on snow condition, pace, and time spent wildlife spotting. Fresh snow = faster skiing. The shuttle saves your legs on the return.

Q: Do I need to book the shuttle in advance?

Yes, especially December and weekends. Call 307-344-7311, toll-free 866-439-7375, or book at Mammoth Hot Springs Hotel. Shuttle often fills; don't show up hoping for a spot.

Overview

About This Trail

The Sheepeater Ski Trail is a low-angle, 5-mile winter route ideal for introducing new skiers to backcountry travel. Gently rolling terrain (60 feet elevation) cuts through mixed forest and meadow with consistent views of Swan Lake Flats and the Gallatin Range. This is attainable skiing, not a lung-buster, but winter exposure is real—wind, cold, and possible whiteout demand proper layers and hydration discipline. Shuttle access from Mammoth Hot Springs means you don't exhaust yourself just getting there.

Insider Tips

["Book shuttle well in advance (at least 1 day ahead, ideally 3+ days for weekends).", "Arrive at the lot by 7 AM. Parking fills, and shuttle availability isn't guaranteed.", "Check shuttle schedule and snow conditions by phone before driving (307-344-7311).", "Layer aggressively and shed one layer immediately if you start sweating. Wet clothing kills you.", "Make constant noise (talk, whistle, bells). Bison and elk don't retreat; they don't know you're coming.", "Carry 2L water minimum. Winter dehydration is silent and deadly."]

Hiking Tips

["Hydration kills you in winter—you won't feel thirsty, but dehydration is fatal. Carry 2L minimum.", "Make constant noise. Bison and elk don't retreat; they don't know you're coming.

Federal law.", "Check shuttle availability before you drive. Call ahead; don't show up and hope.", "Bring map and compass. Trail markers hide under fresh snow; navigation skills are essential.", "Trekking poles help in deep snow and provide stability on ice."]

FAQs

Can I do this as a beginner skier?

Yes, but with caveats. Terrain is easy (60 feet elevation over 5 miles), but winter conditions are unforgiving. You need basic ski or snowshoe skills and proper gear. If you've never done winter trail skiing, this is still achievable—shuttle access doesn't penalize you for a slower pace.
