The Lehigh Gap Wildlife Refuge consists of over 750 acres of varied habitat. The trail system threads through these habitats and provides visitors with approximately 13 miles of hiking trails at present. Loop hikes can easily be planned so that hikers need not retrace their steps. We hope you come out to the Refuge and enjoy the many hiking opportunities. Since 2002 we have been busy, along with our friends from the Allentown Hike Club, creating additional trails to connect to the existing Appalachian and Blue (North) Trails at the top of the mountain and other areas of the Refuge. Today you can come out to the refuge for a peaceful walk along level terrain, challenge yourself on some of the steeper trail sections, or do the Big Hike covering the entire trail system.
Most people begin their visit to the Refuge at the Osprey House, headquarters of the Lehigh Gap Nature Center. Access to the Refuge is also available from Riverview Road at the western edge of the Refuge or from hiking in on the Appalachian Trail. Three trails meet at Osprey House parking area the Prairie Warbler Loop, D&L and LNE trails.
