The uninhabited island of Big Major Cay in the Bahamas is populated entirely by swimming pigs.

Known as the Swimming Pigs of Exuma, the feral pigs swim freely in the shallow, clear-water ocean and play amongst themselves on the beach.

How the pigs got on the island is still a mystery. Some believe that they were dropped off by hungry sailors who never returned — others think the pigs survived nearby shipwrecks.

You may have already swum with dolphins, but what about the ever-elusive pig on this beautiful beach? Prepare to check off this excursion from your bucket list.
