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

The area features several access points including Roy Bridge on Route 615 and Brook Road from Route 560, with parking available along Mountain Road; note that the Three Bridges area on Mountain Road is currently closed to vehicular traffic due to bridge structural concerns, though foot access remains available.

Visitors can enjoy hiking, birdwatching, and winter cross-country skiing on the 2,093-acre tract, which is managed for upland game, deer, waterfowl, and fishing.
