Terrell River Loop

The Terrell River Trail begins at the Terrell River County Park parking area near Smith Point Road in Mastic Beach, New York. This mellow coastal route winds through maritime forest and skirts a tidal estuary before reaching open views of the Great South Bay. Hikers can explore several side paths that form optional short loops along the main trail, offering alternate perspectives on the salt marsh and surrounding wetlands. The route is flat and easy to follow, making it ideal for a casual walk or slow-paced nature outing. Expect shaded sections under pitch pines and oaks, transitions to grassy wetlands, and open stretches with marsh grasses and estuary views. Bird activity is high year-round, with regular sightings of osprey, egrets, and migratory shorebirds. In warmer months, plan for insect exposure—mosquitoes and ticks are common. The trail has no water sources or services, so be sure to carry everything you need. This peaceful walk rewards hikers with up-close looks at Long Island’s dynamic coastal habitat.
