Flatbrook Roy Wildlife Management Area offers multiple access points to the Big and Little Flat Brook trout streams, including a handicapped-accessible fishing area at the Three Bridges parking lot and additional parking at Roy Bridge.

The area features dirt parking lots and woods roads suitable for foot access, though the Three Bridges area on Mountain Road is currently closed to vehicular traffic due to bridge structural concerns—visitors can park along Mountain Road before the closures or use alternate routes via Roy Bridge on Route 615 or Brook Road from Route 560.
