Getting there may take some effort, but the dip is worth the trip.

Cenote Dzitnup, 100 miles west of Cancún, boasts an impressive stalactite ceiling as well as potably pure water.

Just be sure to wait 30 minutes before swimming.

First, you've got to get to Koh Muk, an island off the coast of southern Thailand, but from there it's pretty simple: Hop a boat to the island's west side, wait for low tide, jump into the shimmering blue-green waters of the Andaman Sea, and swim through a 250-foot tunnel. Or just keep scrolling through these pictures.
