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 0204 is in the Huckleberry Rocks Area. It's probably the most challenging of the Huckleberry Rocks trails. 0204 is very wet and boggy. At least 33-inch wheels, 4Lo, traction boards, and a winch are all recommended for this trail. Where there aren't puddles, the surface is waterlogged grass and mud, so try to maintain your speed.
