TrailAvalanche Peak Trailhead 5N2
4.5-mile out-and-back; 2,100 ft gain. Relentless climb with a true summit payoff.

The Bannock Ski Trail is 2 miles of mellow winter skiing through meadows and mixed forest—perfect for building backcountry confidence. Only 132 feet of elevation gain on a mostly flat old road bed. You'll cross a narrow bridge over Soda Butte Creek, then traverse open meadows where bison and elk roam—which means respecting wildlife distance rules (100 yards from bears/wolves, 25 yards from others). This is easy terrain, but winter conditions and wildlife require your full attention.
Easy
Accessible winter ski through Yellowstone meadows with frequent wildlife encounters (bison and elk). Mix of open meadows and forested terrain. Gateway to North Absaroka Wilderness at 1 mile from trailhead.
• The bridge crossing at the start feels narrower than it is. Approach at a walk to build confidence. • Meadow sections are wind-exposed. Winter winds come from the west—expect wind in your face heading east toward Silver Gate. • Bison often rest in meadow depressions. They're easier to spot early morning or late afternoon. • Silver Gate is your turnaround point for most skiers. Beyond it, the road becomes a snowmobile route.
Winter
Suitable for families with basic winter skiing or snowshoeing skills. Mellow terrain and wildlife viewing appeal to kids. Teach children wildlife distance rules (100 yards from bears/wolves, 25 yards from bison) and bridge safety. Cold exposure is the real concern—ensure proper layers.
Skiers praise this trail as an accessible entry point to Yellowstone winter backcountry. The mellow terrain suits beginners, while wildlife encounters and winter conditions keep things interesting. Most visitors rate it as an easy, confidence-building winter ski with natural appeal.
No permit required for general use. Qualified service animals must have a backcountry access permit and remain leashed at all times.
No shuttle required. Warm Creek picnic area parking is at the trailhead.
Bison and elk frequent the trail. Federal regulations require 100-yard distance from bears and wolves, 25 yards from other animals. Narrow Soda Butte Creek bridge at start requires sure footing. Winter cold poses serious hypothermia risk if unprepared.

Yes. It's marked easy for a reason—132 feet of gain and flat terrain are genuinely forgiving. But you must control your skis, dress in layers, and stay alert in winter conditions. Take it slow, build confidence, and don't push your limits.
Not advisable. Bison, elk, bears, and wolves live here. If you get injured miles from the road, you need a partner to help. Pair up. Wildlife encounters happen; you need backup.
Cold exposure and hypothermia. Moving keeps you warm, but a break can flip you into danger fast. Layer properly, don't strip off clothes, and know the signs: shivering, confusion, slurred speech. Treat cold as seriously as the bears.
Bison and elk frequent the meadows. Stay 100 yards from bears and wolves, 25 yards from everything else (federal rule, not a suggestion). Make noise as you travel. Do not approach animals for photos or block their escape routes.
No permit for general skiers. Service animals require a backcountry access permit. Check the NPS website for specific requirements.
The Soda Butte Creek bridge at the start is narrow but stable. Approach at walking speed, not on skis. Test your footing. If you're uncomfortable crossing, turn around—no shame in it.
Plan 1-2 hours for the 2-mile trek out. Return is another 1-2 hours on the same trail. Total outing: 2-4 hours depending on fitness, snow depth, and how long you pause to watch wildlife. Don't rush—this isn't a race.
