Avalanche Peak Trail

Use the roadside pullout at Eleanor Lake on East Entrance Road, about 19 miles east of Fishing Bridge Junction and 8 miles west of the East Entrance. Cross the road; the trail begins on the other side, to the right of the creek. There is an information kiosk at the access. Parking capacity is not documented. No reservation or separate activity fee is required, though park entry fees may apply. No food or drinking-water stop is documented along the route, so carry what you need.

The path starts steeply through dense lodgepole pine, Engelmann spruce and subalpine fir. The first stretch has few switchbacks and limited views; expect to watch your footing rather than look out across the park. A small meadow opens the trees roughly three-quarters of a mile in, then the route climbs back into forest and whitebark pine. The main bowl comes into view just over a mile from the start.

At the base of Avalanche Peak’s bowl, take the trail left and follow its switchbacks across large talus slopes to an open, nearly level patch below the summit. The loose small stones make this section tiring, especially on the way down, when it is easy to skid. Hikers often recommend sturdy footwear and poles for traction and balance. Snow can linger into early summer and cover the established tread; do not assume that a line of footprints is the right route.

From the open area, the established path climbs to a narrow ridgeline. This is the most exposed part of the hike; cross carefully and turn around if the footing or weather feels wrong. The summit opens onto Yellowstone Lake and a sweep of remote high peaks, including the Absaroka Range; the Teton Range can also appear in the distance. The route returns by the same trail, so save energy for the loose, steep descent.

Above treeline, lightning is a serious hazard. Even on a warm day, carry rain gear and warm layers, including a hat and gloves. Snow often covers the trail until early July. Grizzlies use the whitebark pine area for its nuts in fall, and Yellowstone advises against this hike in September and October; if you hike in other seasons, carry accessible bear spray and travel in a group of three or more. The park does not allow pets on the trail. The high elevation and strenuous climb also make this a poor choice for people with heart or respiratory problems.

The route passes through the upper forest into open alpine terrain, where whitebark pines and their exposed, sometimes dead trunks mark the transition toward treeline. Their nuts help explain why grizzlies visit this slope in fall. From the ridge, look back toward the lake and surrounding ranges: the climb trades the forest’s close, shaded feel for a broad view over the eastern side of Yellowstone.
