Wilderness Landscape & Natural Heritage
Fort Indiantown Gap Military Reservation (FIG) spans over 17,000 acres in Lebanon and Dauphin counties, Pennsylvania. Originally developed during World War II, it remains an active military training site for the Pennsylvania National Guard and serves multiple defense functions. The reservation is located in the Ridge and Valley region of the Appalachian Mountains, featuring rolling hills, mixed hardwood forests, open fields, and riparian corridors. Its varied topography supports habitats for white-tailed deer, wild turkey, and many migratory bird species, making it a popular destination for wildlife viewing and hunting outside of active training periods. Outdoor recreation options include extensive hiking and mountain biking on established trails, fishing in the reservation’s lakes and streams, and limited primitive camping in designated areas. The landscape is punctuated by shooting ranges, military training facilities, and historic features including remnants of World War II era infrastructure. The area's natural setting attracts birdwatchers and photographers, while its proximity to populated areas makes it accessible for day trips and weekend outings. Managed with an emphasis on balancing military use with conservation and public enjoyment, Fort Indiantown Gap offers a unique combination of protected natural resources and active defense operations. Visitors are reminded the reservation is primarily a defense installation, with certain areas subject to closures and access restrictions for safety and operational reasons.
