Nantucket is blessed with pristine sandy beaches for every vibe and mood. Beaches along the harbor and on the north shore, protected by the Nantucket Sound, have calm waters, while south shore beaches such as Surfside and Cisco get heavier surf. Surfside Beach is Nantucket's most popular, where surfers and fishermen enjoy big waves and a wide beach. College kids and surfers head to Nobadeer and families flock to Jettie's Beach and Children's Beach, where gentle waves lap the pristine sand. Brant Point is the perfect place to relax, watch the boats in the harbor, and take pictures of the beach and picturesque lighthouse. Many Nantucket beaches have seasonal lifeguards and facilities.
