Dive Site: South Ari Marine Protected Area

About South Ari Marine Protected Area

The South Ari Marine Protected Area (SAMPA), often simply called Maamigili, lies within the breathtaking South Ari Atoll of the Maldives. Established in 2009, this 42-square-kilometer zone along the seaward edge of the atoll is globally acclaimed for consistently offering year-round whale shark sightings, a rare phenomenon in the diving world. Divers and snorkelers flock here specifically for the high probability of encountering these majestic creatures. The topography of SAMPA primarily features outer reef walls and slopes, with depths typically ranging from 5 to 15 meters, making it accessible for various experience levels. While whale shark encounters are often snorkeling-focused due to their presence near the surface, the area also offers gentle drift dives along reef contours. Beyond the whale sharks, the vibrant reefs teem with diverse marine life, including graceful manta rays, various reef sharks, eagle rays, and sea turtles. The region's marine life is rich, benefiting from nutrient-rich waters. Whale sharks are present year-round, predominantly juvenile males. Manta rays are common, especially during the northeast monsoon (December to April), congregating at cleaning stations like Rangali Madivaru. Other frequent sightings include blacktip and whitetip reef sharks, nurse sharks, and various reef fish. The Kudhimaa Wreck, a purposeful sinking, has transformed into a thriving artificial reef, offering another unique dive experience. Ethical and sustainable tourism is central to SAMPA, with strict regulations in place to protect the whale sharks and their habitat. Visitors are guided through responsible interaction protocols, ensuring a respectful experience. Most excursions begin with a boat trip searching for whale sharks near the surface, followed by cautious entry into the water, allowing for extended observation periods with these magnificent filter feeders.

Conditions & Currents

Currents within SAMPA are generally mild, contributing to a relaxed diving and snorkeling experience, especially during whale shark encounters where these giants cruise slowly. However, drift dives along reef slopes are common, guided by the prevailing currents. Entry points are typically from a boat, and descents are usually assisted by the current. While moderate currents can occur, particularly during monsoon transitions, they generally facilitate easy drift diving, making navigation straightforward along the reef contours.

Dive profile & how the dive runs

Dive excursions in SAMPA typically involve a boat trip along the protected southern reefs in search of whale sharks. Once sighted near the surface, boats approach cautiously following strict regulations. For snorkelers, a calm entry allows observation in shallow depths of 5-15 meters. For divers, while many whale shark encounters are snorkeling-focused, it's possible to encounter them on scuba during a drift along the reef, such as Maamigili Beru. Reef dives involve boat entry, descending with the current, and drifting along reef slopes. The Kudhimaa Wreck offers a dedicated profile, with the ship sitting upright and intact. The wreck dive typically explores the prominent wheelhouse, large propeller, and crane structures. Safety stops are generally conducted as part of the slow ascent back to the boat, which will pick up divers upon surfacing.

Underwater photography

Capturing the iconic whale sharks in SAMPA requires a wide-angle lens, given the sheer size of the subjects and the desire to include surrounding water. Natural light is often sufficient in the clear, shallow waters, but external strobes can enhance colors and sharpness, particularly when shooting at depth or against the sun. For wreck photography at Kudhimaa, a wide-angle lens is also beneficial for capturing the entire structure, while macro lenses can be used for smaller critters like frogfish or ghost pipefish. Maintain excellent buoyancy to avoid disturbing marine life or kicking up sediment, especially around the wreck. Always respect the whale sharks by keeping a distance and avoiding sudden movements; observe without intrusive behavior to ensure ethical interactions.

Getting there & logistics

Access to the South Ari Marine Protected Area is typically via Velana International Airport (MLE) in Malé, followed by a domestic flight to Maamigili (VAM) or a seaplane/speedboat transfer to various resorts in South Ari Atoll. Many divers combine SAMPA into a broader Central Atolls liveaboard itinerary, which often departs from Malé. Alternatively, several resorts in the South Ari Atoll offer daily dive trips to the protected area. Trip lengths vary, from day excursions for whale shark encounters to multi-day liveaboard or resort packages. There are no specific entry fees for the marine protected area itself beyond standard dive trip costs. Liveaboards provide access to multiple sites, while resort-based diving offers flexibility for daily excursions.

Safety & environment

Safety in the South Ari Marine Protected Area is paramount, especially during whale shark encounters where adherence to responsible interaction protocols is crucial. Always maintain a respectful distance from marine life and follow your guide's instructions. The nearest recompression chamber is located in Malé, requiring evacuation by seaplane or speedboat in an emergency, underscoring the importance of comprehensive dive insurance. Site-specific hazards include boat traffic, particularly during peak whale shark season, making the use of an SMB (Surface Marker Buoy) highly recommended during reef dives. While currents are generally mild, stronger currents can occur, necessitating good buoyancy control. All divers should ensure their equipment is well-maintained and that they are medically fit for diving.
