The Bighorn Tack-On WSA includes public lands in both Montana (2,470 acres) and Wyoming (80 acres). This information encompasses the entire WSA. Two caves in the WSA provide spelunking opportunities. These opportunities could not be considered outstanding, however, because of limited access and, in one situation, a dangerous point of entry. For experienced climbers, the possibility of rock climbing exists on some of the sheer limestone cliff faces and pinnacles. Hiking and associated photography and sightseeing activities are outstanding. The topographic relief, the unique geologic formations, and the wide expanse of rugged country within view from the ridge tops presents a variety of challenges to potential users.

Visitation Information

The WSA is a narrow strip of public land in Montana and Wyoming bordering the Bighorn Canyon National Recreation Area. Elevations range 4,040 ft. in the south to 8,100 ft. in the north. Motorized travel is expressly prohibited. Additionally, the WSA is closed to mineral entry, including gold panning.

Visitor Advisory

Access to wild lands inherently requires good navigational skills and four-wheel drive or high-clearance vehicles. Visitors should be prepared for adverse weather and road conditions. The WSAs in the BLM Field Office are primarily accessed by unnamed or unsigned two-track roads that in many cases may be difficult to find without sufficient navigational skills and equipment.

Wilderness Study Areas

WSAs are undeveloped federal lands that retain their primeval character and influence, without permanent improvements or human habitation, and are managed so as not to impair their suitability for preservation as wilderness. Backcountry recreation is a common use along with Leave no Trace Outdoor ethics. Please be advised these areas are restricted and do not allow for the use of motorized and mechanized equipment.
