6Sanibel Island, Florida, USA

Sanibel Island, on the Gulf Coast of Florida, is regularly nominated as the best beach in the world to find shells.  

The east-west torque of Sanibel’s south end acts like a shovel, scooping up all the seashells that the Gulf collects from the Caribbean and other southern seas including conchs, whelks, scallops and clam shells, often perfectly intact. The island has become so popular with beachcombers that some hotels offer rooms with special sinks and worktables for cleaning shells.
