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

This is a steep lung-buster: 800 feet of elevation gain compressed into a 1.5-mile climb through dense lodgepole forest. The reward is a panoramic summit overlook of Yellowstone Lake. The route is a lollipop loop—the left fork at mile 0.8 is the shorter approach to the top. Grizzly bears are active here; stay alert, make noise constantly, and hike with a partner.
Moderately strenuous
Panoramic views of Yellowstone Lake and the surrounding area from the summit overlook
• The trail junction at mile 0.8 splits into a loop; the left fork saves 0.4 miles to the summit. • Don't stop at the first viewpoint—the main overlook at the top offers the true panoramic vistas. • The descent is steeper on your body than the ascent; trekking poles are essential, not optional. • Bring a wide-brimmed hat; the summit is fully exposed to sun and wind.

Yes. Grizzlies are active in this area. Make constant noise—talk, clap, carry bear spray if possible. Hike with at least one other person. Never solo in bear country.
Yes, but it's aggressive. The 1.5-mile climb is relentless with few breaks. If you're fit, you'll feel it. If you're not, it'll be slow and tough. Pace yourself and take breaks on the way up.
The descent. Your quads will burn. The terrain is steep with loose footing. Trekking poles are essential. The way down takes longer than the climb for most hikers.
