Wolf Den Run State Park is Maryland's first and currently only park that caters to four-wheeling. There are three designated areas, each with numerous trails. A permit is required. The trails are open year-round except for deer firearms season, the two weeks beginning the first Saturday after Thanksgiving. There is no camping at any of the three offroad locations, but a campground is 1 mile northwest of Huckleberry Roaks Area along N Hill Road.
Trail 1101 starts at the entrance of the North Hill Area and climbs to the highest, wooded section of the NHA. The surface of the trail is pretty rocky but is interspersed with a few medium-depth puddles. Towards the trail's end, the climb becomes very steep with a few isolated rocks but managable with a stock 4WD vehicle. There is also potential for pinstriping. There is plenty of room at the start of the North Hill Area to air down.
