Pennel Run Professional Guide
Detailed Trail Description from our Guidebook
"This hike is rated moderate, mostly due to a moderate elevation gain and a rocky section for the first mile or so. The trail runs alongside Spruce Run—a pristine mountain stream—then passes through a state natural area. This hike is well worth taking, if only to see the unique bridge that volunteers from the Keystone Trails Association built over Spruce Run.
The Youth Conservation Corps built the Thunder Swamp Trail System in the 1970s. It comprises 43 miles of interconnecting trails that lie in the southern region of the Delaware State Forest—80,267 acres in Pike, Monroe, Northampton, and Carbon
Counties. The main trailhead for the system is located on Route 402 in Marshalls Creek, 8.4 miles north of the intersection of Route 402 and US 209 or 1.8 miles south of Snow Hill Road."
