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

The Observation Point Loop is a 2-mile winter-only snowshoe trail that delivers panoramic views without the marathon mileage. You'll climb 160 feet via switchbacks to a turnaround with unobstructed views of the Upper Geyser Basin and Firehole River. The hike is moderate in distance but rated 'More Difficult' due to steep sections, winter conditions, and frequent wildlife—bison and elk use this trail. Go for the views, stay sharp for safety.
More Difficult (NPS rating)
Unobstructed 360° views of the Upper Geyser Basin and Firehole River from Observation Point—the payoff for the 160-foot switchback climb.
• The 'Observation Point' at the top is not the first high point—don't stop at the false summit. Keep climbing to the true viewpoint. • Descend before 2:00 PM in winter to ensure daylight at trailhead. • Fresh snow (12–18 inches) is ideal; deeper snow makes the switchbacks harder to navigate. • The Firehole River section is a great landmark—use it to orient yourself. • Solitary Geyser is visible on the descent; pause to spot it.
Winter (typically December through early March, snow-dependent)
Suitable for families with children who can snowshoe and are comfortable on moderate slopes. The switchback descent is step-heavy—hand-holding may be needed for young children. Short winter days mean little margin for error; turn back early if progress is slow.
Snowshoers rate this as a solid winter workout with excellent payoff. The 2-mile distance is deceptive—the 160-foot elevation gain and winter conditions make it more challenging than mileage suggests. Most say the views are worth the effort, and wildlife sightings are common.
No permits required for day hiking.
No shuttle required. Park at Old Faithful Visitor Center.

The 2-mile distance is short, but the 160-foot elevation gain via switchbacks and winter conditions push it to 'More Difficult.' If you can hike 2 miles on dirt, you can do this—just expect steeper work and slower pace due to snow. Start early and take your time.
Yes. Microspikes alone will fail in deep snow. Snowshoes are mandatory for safe traction on packed snow and switchbacks. Check snow depth (12+ inches ideal) before going.
Yes. Bison and elk frequently use this trail. Federal regulations require 25 yards from bison, 100 yards from bears/wolves. Make constant noise. If you encounter bison, back away slowly and give them the trail.
Carry 2–3 liters minimum. Winter dehydration is silent—you don't sweat visibly, but you're losing fluids. Melt snow only if you have a reliable heat source (not safe on the trail).
Yes, if they can snowshoe and are confident on slopes. The switchback descent is steep—hold their hand. Turn back early (by 1:00 PM) to ensure daylight.
Yes. A high wooden sign points the way from the Visitor Center. Switchbacks are obvious. Bring a map and compass anyway—winter conditions can obscure markers.
