Avalanche Peak Trailhead is a strenuous out-and-back climb around 4.5 miles with roughly 2,100 ft of gain. The surface is packed dirt and rocky scree, with upper slopes that are loose and exposed. The trail is dry for most of the route, and above treeline you’ll face sun and wind with limited shade. Start early to beat the crowds, but be ready for a physical test and a big summit payoff.
Strenuous to Difficult
360-degree summit panorama over Yellowstone Lake and surrounding ranges; alpine meadows and wildlife along the ridgeline
• Stay on the established trail; avoid a false trail to the right near the summit. • Start early to beat thunderstorms; be below treeline by midday. • Pack layers, rain gear, and sun protection; bring bear spray and travel with a buddy. • Microspikes may be needed in early summer; expect loose scree and rapid weather shifts.

Best hike in Yellowstone. Started early and took it slow. The last little bit is worth navigating the tiny pebbles. Just be careful of footing. I’ve told all of my friends about this hike and can’t wait to go back.

Fantastic hike. Hard but the views are worth it. Breath taking. Took my family 6h 45m round-trip including breaks along the way and 45 minutes to take in the view at the top! Take 3x more water than you think you need.

Amazing trail! The views are gorgeous. We started our climbing and just in 20 mins later severe thunderstorm began. It forced all other hikers on the trail to turn back, but we decided to take a risk and kept on going up. In half an hour sky cleared and we found themselves completely alone on the trail enjoying nature and scenery around. At the summit you likely be met by two or three nice and fat chipmunks begging for food 😊. They get accustomed to visitors so much that I was able to touch one of them. They also insistently tried to inspect all our backpacks (one even got trapped inside). Beautiful trail! Highly recommend!

Yes—bear country is native to the area, especially in fall. Carry bear spray, stay loud, travel in groups, and know how to use your spray if needed.
Cell service is extremely limited here; it's safer to hike with others and to carry a plan for emergencies. Let someone know your route and expected return time.
No backcountry permit is required for day hiking, but a Yellowstone park entrance fee applies. Backcountry permits are only needed for overnight camping.
Sturdy hiking boots, layered clothing, rain gear, sun protection, bear spray, trekking poles (helpful on scree), and microspikes may be necessary in early summer.
Arrive early in the day and aim for mid-week visits during peak season to improve chances of solitude.
