Thunder Swamp Trail

The Thunder Swamp Trail (TST) is an 18.3-mile loop in Delaware State Forest, in southern Pike County. The main loop is bisected by PA 402, and the official trailhead is at the trail’s southern crossing of that road, about 15 miles north of Stroudsburg. The system includes a spur trail to Stillwater Natural Area; the spur adds 13.4 miles if hiked in both directions, for a total of 31.7 miles in the system. The TST traverses a mostly flat landscape, visiting many swamps and wetlands. Despite its flatness, the TST offers a challenging hike due to very rocky footway. ​
