Mount Breitenbach is a massive summit that belongs to the coveted Idaho 12ers group. Located in the Lost River Mountains, it is the 5th highest in Idaho while the 4th highest the its range. it sits squarely on the main Lost River crest and, unlike most other 12ers, is well hidden from the highways.

Mount Breitenbach is a complex mountain with many different characteristics. The southwestern slopes tower 6,200 vertical feet above the Big Lost River Valley and are guarded on either side by fellow 12ers Donaldson Peak and Lost River Peak.

Breitenbach's north face is among the most impressive in the state yet rarely is viewed because of its remoteness. The face rises 3,000 feet above the headwaters of the East Fork Pasimeroi River and is hidden by other ridges and mountains.

Most likely the first ascent up Breitenbach was accomplished by W. Boyer sometime in the early 1960s.

When To Climb

This mountain is typically climbed from mid-June to mid September. The earlier in the season you can climb the less scree you will face.


There is camping allowed at the trailhead. Aside from Borah Peak there are no formal facilities at any of the Lost River (or 12 er) peaks

Possible to camp at the saddle, but the going is rough up there.
