Borah Peak

Borah Peak is a 12,666-foot summit in Idaho. With roughly 5,968 feet of topographic prominence, it stands well above the surrounding terrain. The Borah Peak Trail covers 5.4 miles round trip (out-and-back) with about 3,901 feet of elevation gain — a steep, sustained climb. It's rated Strenuous overall.

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 1.36, gaining roughly 3,300 feet per mile — expect a slow, deliberate pace through here. From the trailhead at about 7,398 feet, the route tops out near 11,299 feet. You'll cross above treeline on the way up, so the upper route is exposed to weather — check the forecast and turn around if conditions build. Along the way the route passes a spring (Birch Springs) near mile 0, a cliff (The Nose) near mile 2.72 — useful checkpoints for judging your pace.

Getting There

The trailhead is at 44.13249, -113.83462 (tap for driving directions). It's roughly 125 miles east of Boise, Idaho. 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 Strenuous rating comes from the National Park Service difficulty formula, which weighs total distance against elevation gain. Most hikers should budget about 4.0 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).
