Black River Trail, on the east edge of Watertown off Rt 3, is a wide, paved trail accessible for everyone. This trail is well-used from dawn 'til dusk. The trail is 3.3 miles from end to end and is well-marked with mileage posts from each direction. The Black River end of the trail features a picnic area and access to wide rocks at the edge of the Black River. The river edge is not fenced off and the current is often swift. A close eye should be kept on children and pets. The parking area is near the junction of Ridge Rd and Woodard Rd.
