With some of the most untouched and un-dived reefs in the Northern Maldives, diving in Raa Atoll is popular due to the high density of thilas scattered inside its lagoons. The diverse marine life amongst the caves, overhangs and drop-offs is still unused to man, and as such is willing to come much closer and provide an unbeatable underwater experience where the visitors can enjoy the quintessential Maldives diving experience without the crowds. The Raa's atoll area is equally recognized for offering a high-quality, well-rounded underwater scene, with abundant reef fish, interactive topography, and blue-water visitors.

A home for a dozen luxury resorts, Raa Atoll (also known as Northern Maalhosmadulu Atoll or Maalhosmadulu Uthuruburi) is located north of Baa atoll, and separated only by a thin channel and lies along the western edge of the Maldives. Like its neighbor, Raa opened to divers later than the Central Atolls, and the area still remains relatively un-crowded today. Expect to see an immense volume of fish life with a staggering variety of different species including the pelagic.

Within its 60 kilometer length, Raa boasts over 90 islands, around 16 of which are inhabite although budget tourism is not developed there. Resort based diving is possible on Raa atoll, while liveaboards head to the area in the summer months due to the abundance of manta rays and whale sharks. Malé is one of the Maldives liveaboard departure locations for Raa Atoll liveaboards. On liveaboards combining Raa with the Far Northern Atolls, however, Hanimadhoo or Dharavandhoo may be the port of departure. These destinations can be reached by domestic flights from Velana Airport.

Best Time

Diving in Raa Atoll is possible all year round, but the northeast monsoon from January to May allows the calmest surface conditions while the southwest monsoon from May to November sometimes makes the seas a bit choppy. The visibility between 10 and 20 meters nad the water temperature usually stays between 27 and 30 C meaning that a shorty wetsuit is adequate for most scuba divers.

Currents vary but are usually manageable by all standards when diving within the atolls, rather than in the channels. Most of the dives are therefore within the atolls. However, the mantas and whale sharks are most plentiful from August to November, so consider a trip during that time of year if the giants are your number one priority.

What to See

Diving in Raa Atoll mainly centers on Raa's pinnacles, or thilas, though dive trips sometimes visit a kandu or two as well. Raa thilas exhibit the Northern Atolls' characteristic topography of overhangs and caverns. The color on the reefs comes from vibrant, swaying soft corals, though a couple sites in Raa have nice hard coral, a rarer sight in the Northern Maldives.

The reefs and thilas in Raa Atoll have a lot to offer – the marine life is a diverse from huge schools of tropical reef fish, beautiful soft corals up to eagle rays, mantas, turtles and sharks.
