A five-island national park off Mozambique's Inhambane coast and one of East Africa's oldest marine protected areas, Bazaruto shelters the Western Indian Ocean's last viable dugong population alongside healthy coral barrier reefs, reef mantas, reef sharks, and beaches where all five regional sea-turtle species nest.

Description
Proclaimed in 1971 and expanded in 2001 to 1,430 km² covering all five islands (Bazaruto, Benguerra, Magaruque, Santa Carolina and Bangué), the Bazaruto Archipelago National Park has been managed since December 2017 under a 25-year agreement between Mozambique's ANAC and African Parks—the first marine reserve in that organisation's portfolio. The park's signature feature is conservation rather than crowds: extensive seagrass meadows in the sheltered lagoon between the islands and the mainland support the last known viable dugong subpopulation in the Western Indian Ocean, while the seaward barrier reefs hold over 2,000 recorded fish species and around 500 mollusc species in coral described as among the least disturbed in this part of the Indian Ocean. Diving centres on Two Mile Reef, a long coral barrier between Bazaruto and Benguerra suited to all levels, plus deeper offshore reefs and the advanced, current-swept Cabo São Sebastião to the south. Water is warmest (around 29°C) in December–January and coolest (around 22°C) in August; the cooler, drier winter months of May–September bring the clearest visibility. Marine encounters are genuinely diverse—reef mantas, grey reef and bull sharks, honeycomb and devil rays, turtles year-round, and humpback whales passing July–October—but whale sharks, despite their billing elsewhere in Mozambique, are a true rarity here.
Highlights
What makes this dive worth the trip.
Bazaruto holds East Africa's last known viable dugong (Dugong dugon) subpopulation: aerial surveys flown 2017–2021 over the Bazaruto seascape derived a total abundance of 325 (SD 145) individuals, and roughly 90% of East Africa's dugongs occur here. In December 2022 the IUCN reclassified the Eastern Africa subpopulation as Critically Endangered (criteria C2a(ii)), its area of occupancy now limited to this single location.
Bazaruto is the only known place in the Western Indian Ocean where all five regionally resident sea-turtle species—leatherback, loggerhead, green, olive ridley and hawksbill—not only occur but also nest, with females coming ashore from roughly November to March.
Despite tourism marketing across Mozambique, whale sharks (Rhincodon typus) are genuinely rare at Bazaruto: across more than eight years of continuous boat-based survey transects, BCSS recorded only two—both in 2025, in shallow water off Cabo São Sebastião—because the archipelago lacks the intense upwelling that feeds whale-shark prey further south at Tofo.

Dive sites
5 signature sites at this destination.
Two Mile Reef
The archipelago's signature dive, a long coral barrier reef running between the south of Bazaruto Island and the north point of Benguerra, roughly 4.5 km off the shore. The flat-topped reef, which can break the surface at low tide, slopes eastward into gullies and holds hard and soft corals, anemonefish, fusiliers, snappers, surgeonfish and Moorish idols alongside larger potato bass, kingfish, barracuda, honeycomb and devil rays, blacktip reef sharks and turtles; shy dugongs are an occasional surprise. Depths of roughly 12–22 m and generally moderate conditions make it suitable for all certification levels, with named features including The Aquarium, The Gap, Cathedral and Shark Point.

Cabo São Sebastião
An exposed, offshore pinnacle-and-reef system on the São Sebastião peninsula south of the main islands, reachable only by GPS and reserved for experienced divers. Strong currents and big game fish—often visible from the boat before the dive—draw bull sharks, hammerheads, large groupers and manta rays, with the chance of 'whatever surprise the Indian Ocean can offer'; the two whale sharks BCSS has recorded in over eight years of surveys were both seen in shallow water here in 2025. Surface intervals are often spent searching the open water for dolphins and whales.

Turtle Cove
A BCSS-monitored reef that functions as both a cleaning station and a resting place for migrating turtles, giving it one of the highest turtle-encounter rates in the seascape (turtles appear on nearly half of all BCSS dives). Grey reef sharks are the headline shark here, patrolling the reef alongside resting hawksbill and green turtles. Calmer than the exposed offshore sites, it suits a broad range of divers when conditions allow.

Rollercoaster
One of the BCSS research dive centre's regularly monitored sites in the Bazaruto seascape and among the more reliable spots for shark encounters. The site's sightings records are dominated by bull sharks, grey reef sharks and nurse sharks moving along the reef. As with most Bazaruto reef diving, conditions vary with the tide and the offshore winter season delivers the best visibility, while the megafauna density reflects the park's protected status.

The Canyon (Magaruque)
A deeper offshore feature near Magaruque Island and one of the two main areas where mantas concentrate at the surface to feed on trapped plankton. It is best known for giant manta rays, which generally hold to deeper water elsewhere in the archipelago but aggregate here seasonally—researchers counted more than 30 giant mantas in a single day in February 2021. Manta activity builds from around February as cooling water and upwelling concentrate plankton.
