The Carolina Wildlife Management Area is bordered on the North by Kenyen Hill Trail, on the South by route 91, and is bisected by Pine Hill Road. The area contains a network of mostly doubletrack (old abandoned farm roads), and a small amount of non-technical singletrack. The North South trail runs through the area and is marked with blue blazes. Ignore all signs saying "Hikers Only", the entire area is open to MTBers.
The recomended route is bit complicated, so a map is suggested. A good map of the area (titled "Hiking Trails, Footpaths and Roads in Carolina and Burlingame Wildlife Management Areas") can be purchased at the W.E. Stedman bikeshop in Wakefield. You can also pick up a free map at the Hunter Check station in the Great Swamp Management Area. The Carolina Management area is small enough to be explored in a single day, and makes for a good after work ride if you live in the area. This is a Wildlife Management area, so remember to wear your 200 square inches of day-glow orange during hunting season.
