Beartooth Mountain

At 12,346 feet, Beartooth Mountain is a summit in Montana. The Beartooth Mountain Trail covers 4.4 miles round trip (out-and-back) with about 975 feet of elevation gain — a gradual walk with modest climbing.

The Route

Most of the climbing comes early — the first half of the route does the bulk of the work before the grade eases. The steepest stretch arrives around mile 0.95, gaining roughly 1,500 feet per mile — expect a slow, deliberate pace through here. From the trailhead at about 9,514 feet, the route tops out near 10,489 feet.

Getting There

The trailhead is at 45.00979, -109.51783 (tap for driving directions). It's roughly 75 miles southwest of Billings, Montana. Arrive early on weekends — trailhead lots at popular peaks fill quickly, and cell service is often unreliable once you leave the highway.

When to Go

The reliable snow-free window is roughly July through September. At this elevation, afternoon thunderstorms are a serious summer hazard — start early and plan to be off the upper mountain by midday. Outside that window expect snow travel and bring traction and navigation skills to match.

Know Before You Go

The Moderate rating comes from the National Park Service difficulty formula, which weighs total distance against elevation gain. Most hikers should budget about 2.0 hours of moving time; add margin for breaks, photos and the descent. Download the GPX track from this page before you go — cell coverage is unreliable in the mountains and a saved route works offline in any GPS app. Conditions change: verify current access, closures and weather with the official land manager before you go. Trail data is sourced from OpenStreetMap contributors (ODbL).
