Borah Peak Hiking Guide (Idaho Highpoint) – Route, Difficulty & Tips
Borah Peak is the highest mountain in Idaho at 12,662 feet and towers over the Lost River Range, making it the most sought-after state highpoint in the region. Often referred to as Mount Borah, this classic hike follows the Southwest Ridge and is the most popular of Idaho’s 12ers. Along the way, hikers encounter the aptly named Chicken Out Ridge—a knife-edged Class 3 scramble that turns many around. While a well-defined trail exists for much of the route, the final stretch can be difficult to navigate for novice climbers. This Borah Peak hiking guide covers the route, difficulty, key hazards, and what to expect on Idaho’s most iconic summit. The mountain is also home to the Borah Glacier, a rock glacier on its north slope and the only active glacier in Idaho.

Route Overview
The standard route follows the Southwest Ridge from the trailhead near Birch Springs Road. The trail begins well-defined but quickly steepens as it climbs toward the ridge. Terrain becomes rockier and more rugged with elevation gain. After crossing Chicken Out Ridge, the route continues on steep slopes where the trail becomes less distinct. Near the summit, multiple use paths branch off, making route-finding more difficult, particularly on the descent.
How Hard is Borah Peak?
Borah Peak is rated Class 3, requiring the use of hands in several sections. The main difficulty comes from exposure rather than technical climbing. While much of the route is a steep hike, the upper mountain and ridge demand careful movement. Hikers comfortable with scrambling will find it manageable, while those uneasy with heights may find it intimidating.
Chicken Out Ridge
Chicken Out Ridge is a narrow, exposed section that must be crossed to reach the summit. The ridge drops steeply on both sides and is the most mentally challenging part of the climb. There is no true bypass. Most hikers move slowly and deliberately, often using hands for balance. This is the most common turnaround point on the mountain.
Best Time to Hike
Borah Peak is typically climbed between July and September when snow has melted from the ridge. Earlier in the season, snow can linger and significantly increase difficulty. Outside of summer, the route becomes a mountaineering objective requiring specialized equipment and experience.
Tips, Gear, and Common Mistakes
There is no consistent water source, so all water must be carried from the trailhead. An early start is recommended to avoid afternoon storms. A helmet is advised due to loose rock, especially with other climbers above. Common mistakes include underestimating Chicken Out Ridge and losing the trail near the summit.
Should You Hike Borah Peak?
Borah Peak is a rewarding climb, but it is not for everyone. It sits between hiking and scrambling, requiring comfort with exposure. Those with experience on steep terrain will find it a natural next step, while beginners may want to build experience first. Many hikers turn around at Chicken Out Ridge, and doing so is a reasonable and common decision.
