Wellfleet Harbor is the town's working-water side: boats, oyster beds, flats, gulls, and the slower bay light that gives the Outer Cape a different mood from the Atlantic beaches. It is not a single monument, but it is central to understanding why Wellfleet feels like Wellfleet.
Walk the waterfront, time a meal around local oysters, or use the harbor as the starting point for a bay-side paddle. Low tide changes the whole scene.
