Lone Peak Wilderness, Protected mountain area in Utah County and Salt Lake County, United States.

Lone Peak Wilderness is a protected mountain area spanning across the Uinta and Wasatch-Cache National Forests with alpine lakes, dense conifer forests, and sharp granite peaks. The landscape transitions between open ridges and forested valleys filled with streams and rock formations.

Congress designated this wilderness area in 1978 as part of the Endangered American Wilderness Act, protecting it from development. The designation marked one of the first formal conservation efforts for Utah's alpine landscape.

The mountains served for generations as hunting grounds for Ute and Shoshone peoples who traveled through the high valleys and peaks. Visitors today walk through landscapes shaped by centuries of Indigenous use and presence.

Bring navigation tools like a map and compass since GPS becomes unreliable at higher elevations and in canyons. Expect snow on trails into mid-summer and plan for limited or no cell phone coverage once you leave lower areas.

The Pfeifferhorn, at 11,326 feet, is also called Little Matterhorn Peak, while Lone Peak reaches 11,253 feet. The wilderness also holds small natural lakes and reservoirs, and snow can linger in some spots until mid-summer.
