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 0101 is in the Huckleberry Rocks Area and is a straightforward loop from which several other trails branch out. Most stock 4-wheel drive vehicles will have no problem. Nothing more than 4Hi is required due to a few muddy puddles no deeper than 6 to 8 inches.
