The Flatbrook Roy Wildlife Management Area provides public access to Little Flat Brook, one of New Jersey's premier trout streams, with multiple parking areas and a handicapped-accessible fishing area at the Three Bridges location.

Access points include dirt parking lots at various bridges along Mountain Road and Walpack Road, with the Three Bridges area offering a mile-long walk to Roy Bridge through mature forest habitat.

The area supports both fishing and paddling activities, with trout stocked throughout spring and fall, though visitors should note that special regulations apply to portions of Big Flat Brook.
