It's famous for having a three-decade-old shipwreck in the middle of it that tourists can explore when they get tired of laying out.
It features a naturally occurring oculus on top of a secluded beach and is a mesmerizing sight to behold when the sun illuminates it from above.
Known as "Secret Beach," this shoreline tells it all. Because there are no public routes to it, residents love it on Kauai's north coast.
Since this beach is surrounded by land, how do you get there? You must dive underwater down a small tunnel to reach the secret beach.
Dry Tortugas, 70 miles off Key West and only accessible by boat or air, is a nice escape from Florida's bustling beaches.
