South Cape Beach State Park

Mashpee's only ocean beach — a barrier beach on Nantucket Sound backed by the Waquoit Bay National Estuarine Reserve. Feels wild and undeveloped compared to neighboring Falmouth beaches. Great birding.

South Cape Beach State Park is the wild card of Upper Cape beaches — a long barrier beach on Nantucket Sound that's backed not by a parking lot and a snack bar but by the salt marshes and pine-oak woods of the Waquoit Bay National Estuarine Research Reserve. The contrast with the manicured Falmouth beaches a few miles west is striking: there's a single sandy parking lot at the end of Great Oak Road, a low-key bathhouse, and then nearly a mile of undeveloped shoreline curving east toward the mouth of Waquoit Bay. The water is warm sound water, with a gentle slope and small waves; the back-beach is a working ecosystem of dunes, beach plum, and migratory shorebirds. The town beach section at the eastern end requires a Mashpee sticker; the state park section is open to all with a parking fee. Birders work the marsh trails behind the beach for piping plover, willet, and the occasional clapper rail; fishermen surfcast from the wash at dusk. It's the closest thing the Upper Cape has to a national-seashore experience.
