The Outlaw Cave Trail begins at the Outlaw Cave Campground and provides access to the Middle Fork Powder River Recreation Area. The 1/2 mile trail descends steeply into Middle Fork Canyon, dropping nearly 500 feet in elevation before intersecting the river just opposite the infamous Outlaw Cave. There is no bridge across the river; please use caution if attempting to cross.

Before you start, we recommend that you do not venture out into these areas during periods of inclement weather. Outlaw Cave Road is closed to motorized use during the winter from January 1 through April 14. Please respect private property rights and all posted signs.

From Interstate 90, take exit 254 for Kaycee. Head west on Highway 191 for about 1 mile. Turn left onto Highway 190W for about 16 miles to Barnum. Turn left onto Bar C Road (sign for Middle Fork Powder River Management Area). This road is an improved all-weather access road and travels directly through the headquarters of the Hole-in-the-Wall ranch. The road will continue west another 2 miles past the boundary to the Middle Fork Management area, and then another 5 miles to the campground. The trail begins at the campground.
