South Ari Atoll Marine Protected Area

One of the few places whale sharks stay all year

The South Ari Atoll Marine Protected Area covers 42 square kilometres of outer reef, a strip one kilometre wide running from the western reef edge at Rangali to the northern reef at Dhigurah. It is one of the only places in the world where whale sharks are resident year-round, and they draw a large number of visitors to the atoll each year. Twelve threatened vertebrate species occur inside the protected area.

Also known as South Ari MPA, Maamigili Beru, Maamigili Whale Shark Site.

The dive

The dive at Maamigili Beru is a long drift along a thin fringing reef that runs between Holiday Island and Sun Island on the southern edge of Ari Atoll. The reef is a gentle slope down to a sandy floor at 30 m, and you go in with the tide: on an incoming current the reef sits on your right shoulder, on an outgoing one on your left. Either way you cover a long distance from entry to exit with very little finning, past moray eels, fire dartfish, anemones and the occasional whitetip reef shark on the slope.

Much of the attention stays above the reef. Boats work the length of the 42 square kilometre protected strip - a kilometre wide, from the western reef edge at Rangali to the northern reef at Dhigurah - watching the surface for a whale shark, and a sighting usually turns into a group snorkelling alongside it for as long as it stays up. If you are lucky one passes while you are on scuba. Schools of blue-stripe snapper hold facing the current, and Napoleon wrasse, turtles and the occasional manta ray come through.

Questions divers ask

Are whale sharks in South Ari Atoll year-round?+

Yes. This is one of the only places in the world where whale sharks are resident all year, so there is no season to plan around. They range along the 42 square kilometre protected strip between Rangali and Dhigurah, and boats work its length rather than diving one fixed point.

How deep is the dive at Maamigili Beru?+

The reef is a gentle slope that runs down to a sandy floor at 30 m, so the profile is set by where you choose to sit on the slope. Most of the whale shark encounters happen at or near the surface rather than at depth.
