The Mantas of Hanifaru Bay

Hanifaru Bay: Famous for huge manta feeding aggregations

There probably isn’t a better place in the world to witness aggregating manta rays than in the Maldives' Hanifaru Bay. With the largest known population of reef manta rays (Mobula alfredi), the Maldives is a global manta hotspot on its own. The chain of atolls acts as barrier to the monsoonal currents and creates an upwelling of nutrient-rich cold water. 

The Maldivian marine food chain gets kick-started by the bloom of phytoplankton, which in turn is fed on by zooplankton. As the water gets pushed through the atolls, bioproductivity increases and the highest plankton concentration is found on the leeward sides of the atolls. The local manta population follows their food source. And the result for underwater photographers and manta maniacs is simply unparalleled.

The Manta Rays of Hanifaru Bay

Hanifaru Lagoon is located on the eastern side of the Baa Atoll and has an open channel facing west that leads into a gradually shallower dead-end bay. Between May and November, monsoonal currents push plankton-rich water into the bay. This increases during high tides, when tidal currents push water the opposite way and create a back-eddie, forcing more plankton to get trapped in the end of the bay.

The high plankton concentration can lead to crazy feeding aggegations with up to 200 mantas and (sometimes) whale sharks in the bay. It is an experience of a lifetime to see tons of mantas use spectacular feeding strategies: barrel rolling, chain feeding, and cyclone feeding.

Manta Ray Conservation in the Maldives

As Hanifaru’s popularity has increased in recent years so too has the number of divers and snorkelers—to unsustainable levels. But after UNESCO declared the Baa Atoll a World Biosphere Reserve in 2011, the Maldivian government implemented strict regulation with the scientific help of the Manta Trust organization. 

Only snorkeling and freediving is allowed in the bay, as divers and bubbles in the water column disrupt normal feeding behavior of the animals. As they mostly feed quite close to the surface, diving is not necessary for a great experience.

Boat access and mooring is regulated so as to limit any negative interaction with the mantas. And no boats are allowed into the bay itself. At any given time, no more than five boats and 80 people are allowed to enter the area. A daily alternating schedule between liveaboards, guesthouses, and resorts exists. Tourists must be guided by a certified Hanifaru Bay guide and are briefed on how to behave without disturbing the animals.

Local rangers are present on site and enforce the regulations in water and with the use of drones. Penalties apply for misconduct like actively touching an animal. This has improved the situation for our plankton-feeding friends, and they again come back in high numbers.

Hanifaru Bay Manta Underwater Photography

  • Don’t chase—let the mantas approach you
  • No strobes/lights are allowed without a special permit so it's all about ambient light photography
  • Stay near the surface where there is more light
  • Plankton limits visibility: Use your widest lens to get super close
  • Shoot (slow) burst mode to get the peak of the action 
  • Increase ISO if needed (leaving shutter speed no less than 1/100s)
  • Try locking focus at arm’s length if the plankton poses a problem
  • Try video! Video can often capture the movement and feeding behavior better than stills


Advice for Visiting Hanifaru Bay

The official Hanifaru season is May to November, but it’s a safer bet to plan your trip between June and October. Try to stay over a full or new moon, as there are higher tides and possibly more plankton in the bay. These are often the best periods. 

For accommodation there are three options: resorts, liveaboards and local guesthouses. The closest resort to Hanifaru is Kihaa Maldives, which is a five-minute boat ride away. The Hanifaru Bay trips are organized by the Ocean Dimensions dive center on Kihaa, and it’s possible to go out every other day with one of their experienced licensed guides.

Every second day is reserved for the liveaboards and guest houses, but you can use those days to go diving at several manta cleaning stations that are close to Hanifaru. There you can attach your strobes and get good photo opportunities from a different angle.

As there are huge numbers of mantas in the area between June and October, Baa Atoll is known for diving with mantas and sometimes a whale shark if you get lucky. Most cleaning stations are pinnacles inside the atoll and have nice coral cover with black coral bushes, clouds of anthias, turtles, morays, and plenty of reef fish.

Diving in Baa Atoll offers great photo opportunities with nice coral cover between 30 to 90 feet (10–30m)
