Brewster’s eight beaches on Cape Cod Bay are so shallow and so gradual that you can walk out nearly a mile at low tide—and wade nearly that far at high tide. A Perfect Day in In Brewster starts at Breakwater Beach (off Breakwater Rd.). If the tide is out, you can explore tidal pools for shells, crabs, and small fish. If the tide’s in, enjoy the mild temperature of the water that’s rushed in over the sun-warmed flats. There’s no snack bar here, but a half-mile up the road, the venerable Brewster Store (1935 Main St., 508-896-3744) stocks fresh coffee, penny candy, fudge, and Coke in real glass bottles. It’s also the go-to store for oil lamps and parts, including hurricane globes.
