White Clouds Wilderness Area


Located in Custer County, Idaho, the White Clouds Wilderness is a protected area that includes 90,769 acres of land that was added to the National Wilderness Preservation System in 2015. Part of the White Cloud Mountains are included in the Wilderness Area, which is north of the Hemingway-Boulders Wilderness. Most of the White Clouds Wilderness is managed by the Sawtooth National Recreation Area, with a small part being managed by the Bureau of Land Management (BLM).

Early settlers chose the name White Clouds as a result of there being many light peaks that appeared to blend with the clouds above; resulting in it being difficult to tell what were mountains and what were clouds. A variety of rock types make up the White Clouds, with many of the peaks being made of metamorphic limestone. Visitors to the Wilderness will encounter plenty of recreation opportunities, including hiking, fishing and horseback riding, as well as the chance to experience getting away from it all.

When looking to spend some time outdoors relaxing or engaging in outdoor adventure (or both) consider the White Clouds Wilderness, where you will experience magnificent scenery and plenty of ways to enjoy the views.
