Fenwick is set off from the town center of Old Saybrook by a large cove over a causeway. It is located exactly where the Connecticut River flows into Long Island Sound. The town has two lighthouses, the Inner and the Outer. There is also a single private beach about a quarter of a mile away from the lighthouse. The Inner is at the tip of Lynde Point, Fenwick's peninsula, and the Outer is a quarter mile off shore, connected by a rough jetty. Visit us today.
