3. Crescent Beach
(directions)
This gorgeous stretch of sandy beach on the island's west side offers visitors a perfect spot for swimming, sunbathing, or simply enjoying the beautiful views of the Peconic Bay. The sunsets here are truly spectacular. In the summer, you might also want to visit the Sunset Beach Restaurant and Bar beachfront restaurant right across the street, which turns into a lively spot in the evenings. During the summer season, there are lifeguards on duty and restrooms on-site. You can learn more about this beach and others, as well any permits required, on our Shelter Island Beaches page.
