Known as "the first stop of the East Wind," Chatham's past and present is intertwined with the sea. Chatham is a base of the US Weather Service, and Chatham Lighthouse, which houses the US Coast Guard. Bordering both the Nantucket Sound and the Atlantic, Chatham has first class, comparatively uncrowded beaches, especially the Outer Beach, accessible only by boat or oversand vehicle. Seafaring sights include the Fish Pier, Stage Harbor, and the romantic Chatham fog, which rolls in nightly in the summer. Main Street offers upscale shopping and dining. Chatham also has numerous small festivals and fairs, making it a classic and fun destination for those seeking a memorable Cape Cod visit.
