The World’s 6 Best Atolls Sites to Visit

A ring of coral that naturally developed around an island’s shoreline and continued to develop upward further taking over the island, causing it to erode away slowly is called an atoll. Atolls are generally reef-building corals that flourish only in warm waters. Thus they are only commonly found in the tropics and subtropics. Composed of colorful reefs, thriving marine life and turquoise lagoons, these Robinson Crusoe settings are often the starring images in many beach postcards. If diving is your thing, here are some of the best atolls in the world to plunge into.


Tubbataha Reef

Recognized as one of the best dive spots in the many islands of the Philippines, the Tubbataha Reef is made up of not one but two atolls.

Aside from these coral walls, the dive spot draws in many amateurs and experienced divers annually for the rapidly growing fish colonies and habitats.
