Visit Us

National wildlife refuges offer us all a chance to unplug from the stresses of daily life and reconnect with our natural surroundings. People are encouraged to observe, study, photograph and walk with nature in designated public areas. The best times for observing wildlife are early in the morning and late afternoon. Because of large number of visitors in the spring and fall, wildlife viewing on Sundays is often less rewarding. The refuge has close to 11 1/2 miles of foot access trails, with varying difficulty from which wildlife can be viewed. There are also three wildlife observation blinds and one wildlife overlook. Pleasant Plains Road is a good place to view wildlife from your vehicle. 

Activities

The refuge offers a variety of wildlife-dependent recreational activities that visitors may enjoy. The refuge supports most of  the Big Six wildlife-dependent uses involving hunting, wildlife observation, photography, interpretation, and education.

Please note that there will be maintenance on one of the boardwalks at the Wildlife Observation Center (WOC) from October 9th through October 22nd, 2022 that will result in the temporary closure of sections of the boardwalk leading out to the Garden Club Blind. Thank you for your patience and understanding while we make these modifications to improve the visitor experience. 

Other Facilities in the Complex

Great Swamp is managed as part of the Lenape National Wildlife Refuge Complex. A National Wildlife Refuge Complex is an administrative grouping of two or more refuges, wildlife management areas or other refuge conservation areas that are primarily managed from a central office location.  Refuges are grouped into a complex structure structure
Something temporarily or permanently constructed, built, or placed; and constructed of natural or manufactured parts including, but not limited to, a building, shed, cabin, porch, bridge, walkway, stair steps, sign, landing, platform, dock, rack, fence, telecommunication device, antennae, fish cleaning table, satellite dish/mount, or well head.

Learn more about structure
because they occur in a similar ecological region, such as a watershed or specific habitat type, and have a related purpose and management needs.  Typically, a project leader or complex manager oversees the general management of all refuges within the complex and refuge managers are responsible for operations at specific refuges. Supporting staff, composed of administrative, law enforcement, refuge manager, biological, fire, visitor services, and maintenance professionals, are centrally located and support all refuges within the complex.

Other refuges in the Lenape Complex include: Cherry Valley NWR, Shawangunk Grasslands NWR, Wallkill River NWR.
