Gaafu Dhaalu Atoll.

The southern half of the vast Huvadhoo Atoll system, Gaafu Dhaalu is a frontier for divers and travellers willing to cross the equator's threshold. Huvadhoo is the Maldives' second-largest atoll by area and, with 255 islands between its northern and southern halves, holds more islands than any other atoll on Earth. Its lagoon plunges to roughly 80-90 metres — deeper than any other atoll in the country — and its broad channels draw pelagic life in remarkable concentration: reef and grey sharks, hammerheads, tiger sharks, schooling eagle rays, and whale sharks that visit through the northeast monsoon. Infrastructure remains deliberately light.

A handful of luxury resorts sit on private islands scattered across the lagoon, reached by a fifty-five-minute domestic flight from Velana to Kaadedhdhoo (KDM) and a short speedboat connection. Beyond the resorts lies one of the most archaeologically significant atolls in the Maldives: Thor Heyerdahl's 1983-84 expedition documented coral-limestone stupa mounds on Gan and Vaadhoo, pointing to a Buddhist civilisation that flourished here between the sixth and twelfth centuries. For guests who have already seen the North Male ring, Gaafu Dhaalu offers something rarer — a sparsely-developed lagoon where dive operators regularly have channels to themselves, and where the horizon holds no other resort lights at night.
