Deep Creek Lake State Park located in Garrett County and surrounds Deep Creek Lake, a reservoir that was created with the construction of a dam in 1923. There are trails for hiking and mountain biking as well as water sports on the reservoir. This trail takes a large loop around the park. It circles the base of the mountains and rises to the summit where several cell phone towers and a former fire tower are located. You will then descend the mountain and reach the site of an abandoned coal mine before returning.
