Trexler Nature Preserve, in Lehigh Valley, Pa, formerly known as The Trexler-Lehigh County Game Preserve, is an 1108-acre public park that is a focal point for land conservation efforts within Lehigh County. The Preserve manages and protects natural resources and offers appropriate educational and passive recreational opportunities.

Through the combined efforts of Lehigh County, The Trexler Trust, Wildlands Conservancy and other organizations, the 2006 Trexler Nature Preserve Master Site plan is now being implemented. When completed in 2010, the preserve will offer over 18 miles of trails that can be enjoyed by hikers, bicyclists, equestrians and sportsmen, as well as those who just want to enjoy a picnic at a beautiful Lehigh County location.
