The Flatbrook-Roy Wildlife Management Area offers multiple access points to the Big and Little Flat Brook trout streams in Sussex County, with parking areas at Three Bridges (handicapped accessible), Roy Bridge, and along Route 560 and Brook Road.

Note that the Three Bridges area on Mountain Road is closed to vehicular traffic indefinitely due to bridge structural concerns, though foot access and parking along Mountain Road before the closures remain available; alternate access via Roy Bridge on Route 615 or Brook Road from Route 560 is recommended.
