Located on the bay side of Cape Cod, Brewster beaches are known for their famous tidal flats, which stretch for miles during low tide. Often tucked into quiet seaside neighborhoods, the majority of beaches in Brewster have relatively small parking lots and tend to be less crowded than other spots on the Cape, especially when the tide is out. The calm, shallow waters are great for kids, but be aware that there are no lifeguards at any Brewster beaches.
