Wilderness Landscape & Natural Heritage
Established in 1979, Trexler Nature Preserve spans over 1,108 acres in Lehigh County, Pennsylvania. The preserve features a gently rolling landscape dominated by mixed hardwood forests, open fields, wetlands, and restored grasslands. The area supports a wide variety of native wildlife such as white-tailed deer, wild turkey, raptors, and waterfowl, making it a favored site for bird watching and nature study. Trexler Nature Preserve was originally developed to protect native game species, including a herd of bison and elk introduced for conservation purposes. Visitors can explore more than 20 miles of trails that wind through peaceful woodlands, along peaceful streams, and near open meadows. Popular trailheads and short loops offer accessible hikes, while longer circuit trails allow more extended exploration. The preserve also includes a complex of ponds and a managed wetland that provide habitat for amphibians and migrating birds. Interpretive signage and guided programs are regularly offered by the Lehigh County Parks & Recreation Department, enhancing the visitor experience with educational opportunities. Hunting is allowed on a limited basis during established seasons to help manage wildlife populations sustainably. The preserve offers a serene environment for trail running, mountain biking on select paths, horseback riding, photography, and casual picnicking. The preserve’s proximity to Allentown and the Lehigh Valley makes it a popular natural retreat for both local residents and visitors seeking outdoor recreation in a semi-rural setting.
