Like atolls? The word was invented in the Maldives, a chain of 26 atolls made up of 1,200 islands stretching nearly 500 miles north to south. Out here in the middle of the wild Indian Ocean, currents flow unchecked, so count on advanced drift diving. But it's well worth flying halfway around the world with your safety sausage to take in these stunning reefs packed with fish and big pelagics.
Simply put, you've got two choices in a Maldives dive vacation. You can either plant yourself on one island and dive local reefs, or you can jump on a live-aboard and tour several atolls.
