Sand Mountain Wilderness Study Area


Sand Mountain Wilderness Study Area (WSA) is a 33-square mile property in Idaho named after its most prominent feature, the Sand Mountain, that rises about 500 feet above the surrounding plain. This Bureau of Land Management park offers primitive and unconfined recreation opportunities to visitors looking to enjoy lovely vacations and connect with nature. If you’re coming to the wilderness in your car, ensure it’s a four-wheel-drive vehicle so that you can easily make your way through the rough dirt roads that lead to the park.

Some of the ways to spend time at Sand Mountain WSA include hiking, horseback riding, wildlife observation, and photography. This BLM park is particularly important for wildlife because it serves as a crucial wintering habitat for large mammals such as deer, moose, and elk. More opportunities to view and hunt wildlife are provided at Mud Lake Wildlife Management Area and Camas National Wildlife Refuge. Quayles Lake is a popular destination for anglers at the park.

There are no modern campgrounds or amenities in the WSA, so visitors should gear up for primitive camping. Developed campgrounds are provided at Caribou-Targhee National Forest.
