The gorge serves as a vital corridor for the northern migration of black bears and migratory songbirds.
The Lehigh River through the gorge was once a major transportation artery for anthracite coal headed toward Philadelphia.
The 26-mile rail-trail within the park is part of the larger Delaware & Lehigh National Heritage Corridor.
Most of the white-water flow is supplemented by scheduled dam releases, making conditions highly dependent on reservoir management.
The terrain includes steep cliff faces composed of Mauch Chunk and Pocono formations.
Lehigh Gorge State Park's Rockport Access serves as a primary entry point into a 6,000-acre gorge carved by the Lehigh River. The park features a deep, steep-walled canyon characterized by dense forests and significant remnants of 19th-century industrial history. The main artery for recreation is the 26-mile D&L Trail, which follows the former Lehigh Valley Railroad grade along the river. Whitewater enthusiasts utilize the river for Class II and III rapids, with water levels largely controlled by the Francis E. Walter Dam. The Rockport Access provides specific entry for cyclists, hikers, and boaters looking to explore the middle section of the gorge. The area preserves the corridor once used by the Lehigh Coal and Navigation Company's canal and railroad systems. Geologically, the gorge cuts through the Pocono Plateau, exposing rock layers that date back to the Devonian period. Visitors can access various waterfalls, including those accessible via short spur trails like the ones leading toward the Glen Onoko area.

Check the DCNR website for the latest dam release schedule before planning any whitewater activities.
Bring a repair kit and extra tubes for bicycles, as the crushed stone trail surface can cause punctures.
Maintain high situational awareness near the river banks, as water levels can fluctuate rapidly due to upstream dam operations.
Attempting to swim in the Lehigh River, as dangerous currents and submerged obstacles are common.
Trail sections may close periodically for seasonal maintenance or storm damage repairs.
Carry out all trash; maintain a safe distance from active railroad tracks; keep pets on a leash.
