Lighthouse Beach in Chatham, Massachusetts, is a beautiful, large beach close to the center of the picturesque town of Chatham. It is located across the street from a small Coast Guard Station and the Chatham Light lighthouse. This area was not much of a beach until the Great Barrier Beach broke due to pounding storm swells and hurricanes. The Chatham Break, as it is called, is a growing ocean channel between Nauset Beach and Monomoy Island. This new channel has shifted a significant amount of sand from the north to the south and created this magnificent beach. Nauset Beach protects it from heavy swells, but you can watch the waves crest about 200 yards away at the break. Beach grass, small dunes, and million-dollar homes surround the vast sand beach.
