The park is very friendly towards mtn bikers. Park at main lot and ask where the orange diamond trail starts. The orange diamond is a loop. Look for the white diamond trails that lead off the orange diamond and bring you back. The first white diamond trail has a warning sign on it. Heed it. Great trail in a great location, wonderful views and great singletrack. Not super rocky, but almost. Excellent ride with the white diamonds.
Off route 106 above Carbondale, Fell Twsp, Lackawanna Co, Pa. Merli-Sarnoski County Park
