A UNESCO Biosphere Reserve, Baa Atoll is a cornerstone of the Maldives' northern diving circuit and a destination that consistently delivers exceptional underwater experiences. This administrative division, comprising the atolls of Southern Maalhosmadulu, Fasdhuthere, and Goifulhafehendhu, is home to over 100 coral reefs, extensive mangrove stands, and one of the world's most renowned manta aggregation sites. For anyone planning diving in Baa Atoll, the primary draw is the extraordinary concentration of marine life, a direct result of the monsoon system that fuels the local food chain and supports over 1,200 species of fish.
The crown jewel of Baa Atoll is Hanifaru Bay, a marine protected area on the atoll's eastern edge. From May to November, the bay's unique topography and tidal currents trap nutrient-rich plankton, creating a feeding frenzy that attracts the world's largest known gatherings of reef manta rays, with over 1,800 individuals recorded. During mass feeding events, hundreds of mantas perform 'cyclone feeding', creating a breathtaking spectacle of coordinated spirals. Whale sharks also join the feast, making Hanifaru a global hotspot for two of the ocean's most iconic filter feeders. While scuba diving is not permitted inside the bay itself, many liveaboards include a Hanifaru snorkelling excursion in their Baa Atoll scuba diving tours, with strict visitor limits in place to protect this fragile ecosystem.
Back-rolling in to the invitingly warm water of Maavaru Kandu at Baa Atoll (a.k.a. Southern Maalhosmadulu), divers will descend down initially to the top of the reef at around 8 to 9 metres where ideally they will encounter a gentle current. As with many of the dive sites in Maldives, there are plateaus and overhangs cutting into the side of the reef, but this site promises something exceptional. Every inch of the overhangs which face downward are bedecked in a rainbow of soft corals illuminating the reef in pastel shades of predominantly blue and yellow but also green and mustard. The sight is one of delicate beauty with the delightful colours seeming to glow brightly against the dull shade of the rocky substrate.
The overhangs are huge and you can get right in and fin along while marvelling at the overhead spectacle. The reef also hosts whip corals, brick red sponges, black coral bushes and many zoanthids. Between the overhangs and where the reef flattens out toward the end of the dive, there are more fans of a respectable size and plenty of hard corals: table, stony and mushroom coral. Fish life includes midnight snapper, small-toothed emperor, coral rock cod, moon fusiliers and broad-striped fusiliers, while the shallows play host to thousands of orange basslets as well as moon wrasse and lizardfish. However, it is for the quantity of brightly-coloured pendulous soft corals that this site will live in the memory of scuba divers at Baa Atoll.
Dhonfanu Thila is a pinnacle and a classic example of the exceptional diving at Baa Atoll. The thila comes to a point facing the prevailing current, which splits and runs down either flank. Divers typically drop in up-current, descending to around 22 metres to meet the reef's point. Scuba divers should look of for manta rays here; Baa Atoll is well known for them and this is one site where they are seen regularly. After a few minutes you will see the base of a swim through at 25 metres which you pass and ascend to around 18 metres to find its entrance. The swim-through is quite narrow so care must be taken to pass through, doing no more than brushing past some black coral bushes.
Overhangs provide shelter for yellow-lined snapper and soldierfish in big numbers. Often there are a lot of cleaning wrasses around so expect to see plenty of skin treatments being administered. The site is also home to an unbelievable number of fish: red toothed triggers, black pyramid butterflyish, parrotfish, angelfish, very longnosed butterflyfish, unicornfish and starry rabbitfish among hundreds of species. Another feature of the dive will be that you will see a continuous series of cascading moon fusiliers and broad-striped fusiliers spilling around all over the edges of the reef. Dhonfanu Thila hosts a wealth of life, with more biomass than the eye can take in. With its interesting topography, abundant life and manta ray appearances, this site showcases the best of diving at Baa Atoll.
Dhigali Haa is a submerged pinnacle, the top of which rises from depth to about 7 metres, and there a couple of smaller pinnacles to the western edge of the thila which are also worth exploring. As you empty your BCD and dive down in the water column here, you will likely be greeted by lots of big-nosed unicornfish who seem to enjoy playing in the chimneys of bubbles your exhalations create. Inverting yourself you can see how they rush in seemingly just for the fun of feeling the bubbles tickle their skin. Also off the reef are legions of blue-dash fusiliers, jacks and trevallies which can be seen hunting the small bait fish that swarm in huge numbers around the quieter sections of this Maldives dive site. The quieter areas are also home to yellow-lined snapper, small fans, and scribbled filefish.
Underwater photographers can take 'arty' shots of spiral whip corals, or anemones playing host to pairs of porcelain crabs sweeping plankton towards their mouths with their array of evolutionary devices for so doing. Look out for the Maldivian sponge snail (Coriocella hybyae) here. It is an unremarkable looking snail which could be described in scientific terms as "a dark, knobbly blob". But it is an endemic species to Maldives that moves at around a centimetre a day, so is a good subject for even the slowest of amateur photographers. The top of the thila also has plenty of action with innumerable anthias, basslets and dottybacks holding firm in the current. As with much of this area the sessile life is quite small with no big barrel sponges or large fans. These are more likely to be seen in the channel walls where the big current sweeps are, rather than sites such as this, within the atolls.
Nelivaru Haa is a series of dramatic, star-shaped canyons and channels carved into the reef, creating a labyrinth of overhangs and swim-throughs. The channels are lined by colourful gorgonians and dense soft coral formations. The topography channels the current, attracting a constant stream of plankton and, in turn, a wide array of fish. It is a regular spot for manta rays, which often glide through the canyons, and is also a good site to find hunting trevallies and barracuda. The complex topography provides shelter for numerous moray eels, lionfish, and lobsters. The health of the coral here is particularly impressive, with large table corals and vibrant gardens of acropora on the shallower sections, making this a visually stunning dive that showcases the healthy reef environment of the area.
A smaller, less-visited pinnacle, Dharavandhoo Thila offers a more intimate diving experience. The thila is capped at around 10 metres and slopes down to over 30 metres, with its flanks covered in a dense carpet of soft corals, sea fans, and sponges. The site is particularly good for observing schooling fish, with large aggregations of snappers, sweetlips, and fusiliers often forming around the pinnacle's summit. The overhangs and small caves are home to resting turtles and whitetip reef sharks. The site's quieter nature means that macro life thrives here; expect to find numerous nudibranchs, flatworms, and shrimps in the nooks and crannies. Dharavandhoo Thila is a fantastic alternative for those looking to escape the busier sites and enjoy a more secluded Baa Atoll dive.
Located near the island of Horubadhoo, the protected site of Horubadhoo Thila is known for its prolific marine life and accessible depths, making it suitable for a wide range of divers. The thila rises from a depth of around 30 metres to a shallow summit at 5 metres, allowing for a long and varied dive profile. The site is rich in both hard and soft corals, with large stands of staghorn and table corals providing habitat for a myriad of reef fish. It is a common site to see turtles, and the cleaning stations on the pinnacle attract a variety of visitors, including reef sharks and occasionally mantas. The shallows are ideal for a safety stop, where the sunlight illuminates a vibrant garden of anemones, clownfish, and darting anthias.
