Middle Fork Powder River


Sited in a remote and less discovered part of Wyoming is the Middle Fork Powder River, an area that offers unsurpassed beauty and spectacular opportunities for outdoor recreation. This Bureau of Land Management river park, located 21 miles west of Kaycee, is part of the Old West rich with legends of outlaws and bandits. Some of the land in the area is privately owned, so visitors are encouraged to be on the lookout for such places as they approach and explore the park’s areas.

Opportunities for recreation abound here. If you fancy water-based recreation, you can knock yourself out with any of the available activities such as fly fishing for trout and hunting. Hiking enthusiasts are pushed to their limits on the short Outlaw Cave Trail that brings out the best in them. Visitors with cameras also enjoy good photography around the park’s beautifully decorated areas. Recreational opportunities such as OHV riding, bicycling, mountain biking, and picnicking are also available to guests that visit remote areas in the park and attractions outside the park.

Free camping opportunities are provided in a BLM campground around this river park. Additional campgrounds are available at Boysen State Park and Bighorn National Forest.
