The Refuge is open daily from dawn to dusk. CapeMay National Wildlife Refuge is comprised of three units.
The Great Cedar Swamp Division is at the northern end of the refuge in Dennis and Upper Townships.
The Delaware Bay Division is located in Middle Township and extends along five miles of Delaware Bay. Thousands of shorebirds, including red knot, ruddy turnstone and sanderling use the bayshore habitat during migration.
The Two Mile Beach Unit is a barrier island with beachfront, tidal ponds and maritime forest in Lower Township. The site is important for the federally listed piping plover (threatened), the state endangered least tern, and American black duck.
There are four hiking trails throughout the refuge. These include Cedar Swamp Trail in the Great Cedar Swamp Division; Woodcock Trail and Songbird Trail in the Delaware Bay Division; and Dune Trail at the Two Mile Beach Unit.
