Located in the Bald Eagle State Forest, just south of Interstate 80, Duncan Trail is a rugged and tight drive following the southern contours of Nittany Mountain. The overgrown foliage along this trail will leave you feeling accomplished, as if you were the first person in ages to bushwhack your way from point to point. The dense tree cover cleverly tries to portray this short trail as secluded and alone, but users can rest easy knowing you are only a stone's throw from the highway.
