Barnstable County, Massachusetts

Cape Cod’s heart beats in Barnstable County. This coastal area sits on the southeastern tip of Massachusetts, jutting out into the Atlantic.
It’s a place with sandy beaches and quaint towns. Hyannis, with its harbor, was once the summer playground of the Kennedys.
You’ll find lighthouses along the shoreline. They’re like beacons guiding ships through treacherous waters for centuries. Seafood here is unbeatable. Whale watching is a must.
