Grandmother Mountain Wilderness Study Area

Idaho

Grandmother Mountain Wilderness Study Area encompasses rugged BLM-managed terrain in central Idaho, featuring heavily forested drainages, bare rocky peaks, and several high mountain lakes. Elevations range from 4,600 feet along Lund Creek to 6,800 feet on Widow Mountain, creating diverse ecosystems and dramatic scenery throughout.

Dispersed camping is permitted across the wilderness study area, allowing visitors to establish primitive campsites away from established sites. No developed campgrounds exist within the boundaries, so visitors should arrive prepared with all necessary supplies and practice Leave No Trace principles.

The trail system supports hiking and horseback riding through mixed conifer forests and alpine meadows. Wildlife viewing opportunities are excellent, with the varied terrain supporting diverse species. Hunters frequent the area during fall seasons, while photographers find compelling subjects year-round.

Access requires high-clearance vehicles on unpaved roads, with conditions varying seasonally. Snow typically limits access from late fall through spring, making summer and early fall the primary visiting seasons. Water sources exist but should be treated before consumption.

Visitors should carry detailed maps, as cell service is unreliable throughout this remote backcountry area.
