Mount Bonneville

Mount Bonneville is a mountain summit in the Wind River Range in Wyoming, rising above 12,500 feet within the Bridger-Teton National Forest. Steep rock faces and multiple climbing routes make it a technically challenging destination for experienced mountaineers.

The peak was named after explorer and trapper Benjamin Bonneville, who traveled through the region in the 19th century. The first recorded ascent took place in 1946 by Stewart, Weir, and Willits.

The peak serves as a training ground for mountaineers preparing for advanced climbs in the Wind River Range throughout the year.

Visitors should prepare for alpine conditions and bring proper equipment for high-altitude climbing. The best climbing season runs from July through September, when snow and ice are minimal.

The peak sits at a rare geographic divide between two major water systems. Rainfall here flows either toward the Pacific Ocean or the Gulf of California.
