The Gardner Mountain WSA encompasses 6,423 acres of public land with no state or private inholdings.

The area is generally rugged terrain of the southern Bighorn Mountains dominated by pine, scattered mountain mahogany, and meadows. Beartrap Creek and the North Fork of the Red Fork of the Powder River flow through the area in deep, steep-walled canyons.

Part of the Dull Knife Battlefield, a National Historic Site, extends into the southern part of the area.

The Gardner Mountain WSA offers outstanding opportunities for primitive and unconfined recreation in the forms of hiking, fishing, hunting, and sightseeing. The steep canyon walls, limited number of access points and steep mountainous terrain are natural barriers that affect human movement within the WSA and enhance the primitive character.

There is no direct public access to the Gardner Mountain WSA. Access is predominately controlled by adjacent private landowners and landowner permission is required to cross any private lands. However, the area may be legally accessed via the Gardner Mountain Trail in combination with cross-country travel through steep topography.

The Gardner Mountain Foot and Horse Trail is open to hikers and horseback riders. It ambles through a mountain meadow and then follows a ridgeline overlooking the Gardner Mountain WSA.

Please respect private property boundary signs and practice Leave No Trace! A land status map and compass or GPS unit are strongly recommended.
