Featuring the finest, whitest quartz sand you’ll find in Florida, Crescent Beach is arguably the best of Siesta Key’s three beaches. While not as popular as Siesta Beach, at least in terms of crowds, Crescent Beach makes up for its lack of amenities with Point of Rocks, a half-mile-long rock formation where pirates’ buried treasure is rumoured to rest. We can't promise chests of gold, but snorkel beneath the surface to see marine wildlife that's equally exciting.
