Diving in Alifu Dhaalu Atoll

All year. The protected southern reef from Rangali to Dhigurah is the one stretch of Maldivian reef where whale sharks turn up on a near-daily basis across the twelve months, rather than in a single season. What changes is where: in the dry northeast monsoon, roughly December to April, the animals favour the western side of the atoll, and in the wet southwest monsoon, May to November, they shift east toward Dhigurah. Larger gatherings tend to build from December to March.

For both at their easiest, aim for the dry northeast monsoon, December to April. That window gives the calmest seas, the clearest water and reliable whale sharks on the western reef, and it is also the stronger period for reef mantas at the Madivaru cleaning station. The wet season still delivers both, with more plankton and fewer divers, but visibility drops.

No. There is no national diving permit in the Maldives and no diver-specific entry fee for the protected area, though resorts charge their own boat-dive fees. What does apply is a code of conduct around the protected animals: do not touch whale sharks or mantas, keep your distance, and follow your guide's positioning so the encounter stays calm. Rangers patrol the area and a core no-take zone bans fishing.

It works for both. The whale shark experience along the southern reef is usually a shallow dive or snorkel in the 6 to 25 metre range, accessible to entry-level and junior divers, and several reef and house-reef sites are gentle. The reputation for challenge comes from the channel and pinnacle dives like Kudarah Thila and Broken Rock, where current is strong and a reef hook is standard. A mixed group can split sites by experience.

They share the greater Ari Atoll but dive differently. South Ari is the whale shark and manta atoll, with shallower, easier sites overall and one of the country's best wrecks, so it suits a broad range of divers and liveaboard schedules. North Ari leans into current-fed thila and channel shark dives, including the famous Maaya Thila night dive, and feels more advanced. Many central-atoll itineraries cover both.

You can dive it from a local island. Alongside the seventeen resort dive bases, guesthouse-affiliated dive centres on Dhigurah, Dhangethi and Maamigili run the same protected reefs at a lower price point. Liveaboards on central-atoll routes also call here. Because most sites are reachable from any base, the real choice is budget tier and whether you want resort comfort or a local-island stay.

It sits at the foot of the Machchafushi island house reef, in South Ari. The roughly 50 metre cargo ship, also called the Kudhimaa, was deliberately sunk as an artificial reef in 1998 and stands upright and largely intact, with its propeller, wheelhouse and crane in place. It is now carpeted in coral and is one of the atoll's best macro dives, with lionfish, stonefish, frogfish, ghost pipefish and morays.

For the current sites, yes, treat a reef hook as standard kit. On dives like Kudarah Thila and Broken Rock the current can run hard, and divers tether at a corner to watch sharks hold in the flow rather than fight the drift. Negative entries are common on these dives too. The whale shark reefs and house reefs are far gentler and do not need one.

There are two main routes. A seaplane transfer of around twenty minutes plus a speedboat reaches most resorts, with daytime departures and a night option. For local-island diving, a domestic flight to Maamigili Airport on the atoll's southern island, or a speedboat to Dhigurah, gets you to the guesthouse-diving hubs. The atoll lies about 100 kilometres south-west of the capital.
