The 200-acre Wasque Reservation (pronounced wayce-kwee) is mostly a vast beach. Closing off the south end of Katama Bay, this is where Chappaquiddick used to connect to the mainland. You can fish, sunbathe, take the trail by Swan Pond, walk to the island's southeasternmost tip at Wasque Point, or dip into the surf—use caution, as the currents are strong. Wasque Beach is accessed by a flat boardwalk with benches overlooking the west end of Swan Pond. It's a pretty walk skirting the pond, with ocean views on one side and poles for osprey nests on the other. Atop a bluff is a pine-shaded picnic grove with a spectacular, practically 180-degree panorama. Amenities: toilets. Best for: solitude; sunrise; walking.
