Nice network of singletrack. Rooty, some small climbs, a creek crossing. Generally well maintained except for a few sections. Can easily ride for an hour or so without going over the same section of trail.
From I-95 take the exit for 198 west. Go approximately 1mi and make a left on Old Gunpowder Rd. Pass the Fairland Athletic Complex on your right, then turn right onto Greencastle Rd (approx. 2 mi). A little over a mile, and turn right into the park. Trailhead is located on the left behind the pavillions.
