Something for everyone, tough hills, sweet downs, or you can just tinker around the flats near the top of the mountain. I can't Coopers isn't on the site. Best biking in Northern WV/ Western MD, hands down.
Coopers Rock State Forest is 13 miles east of Morgantown and 8 miles west of Bruceton Mills. Its 12,713 acres are bisected by Interstate 68.
