Hike at Cranberry Bog Nature Preserve

Cranberry Bog Nature Preserve is a tiny jewel set in the wetlands of Riverhead. The park is what remains of an abandoned cranberry-growing operation. The 165-acre preserve serves as part of the drainage system of the Peconic River and is a natural reservoir for Long Island's fresh water supply. The acidic marshes, bogs and wetlands of the surrounding area, made it an ideal habitat for growing cranberries. The focal point of the 1.1 mile loop is the wooden bridge over the bog.

Located on the west side of Lake Avenue in Riverhead, just about a mile south of the traffic circle by the river. Look for a sign that marks the entrance to the preserve. There's a small off-road parking area. You'll need to walk in to the loop trail which takes you around Sweezy Pond. At the end of the old tar roadway there's a sign pointing the way to the start of the trail.
