Two Mile Reef Bazaruto

Vilankulo · Inhambane Province · Mozambique

Two Mile Reef stretches along the eastern margin of Bazaruto Island like an underwater city, a vast platform of coral growth rising from the sandy floor of the Mozambique Channel to within a few metres of the surface. This is the flagship dive site of the Bazaruto Archipelago Marine National Park, and its combination of hard coral diversity, megafauna encounters, and sheer scale makes it one of the finest reef dives in the Western Indian Ocean. The reef earns its name from its three-kilometre length, though the diveable sections focus on areas where coral density and topography create the most interesting terrain. I dropped in at the northern end where the reef slopes gradually from 8 to 22 metres, and the coral garden was immediately impressive. Table corals, staghorn formations, and massive Porites heads create a landscape of living architecture, with the diversity exceeding 100 recorded coral species. Green turtles are virtually guaranteed here. I encountered seven during a single fifty-minute dive, most resting on coral heads or slowly cruising the reef crest. The turtles of Bazaruto are habituated to divers but not tame; they allow approach to perhaps two metres before gently swimming away. Loggerheads, rarer but present, tend to occupy the deeper reef edges. The manta ray cleaning stations on Two Mile Reef activate during the cooler months from May through October, when the northward push of cooler water brings plankton and the mantas follow. The cleaning stations are located on prominent coral bommies at around 12 metres depth, and patient divers who settle quietly nearby can watch mantas circling repeatedly as cleaner wrasses service them. Bazaruto's unique treasure is the dugong. The archipelago supports approximately 250 individuals, one of the last viable populations in the Western Indian Ocean. These shy herbivores graze on seagrass beds adjacent to Two Mile Reef, and while encounters are not guaranteed, they are possible, particularly during calm conditions when dugongs venture into the shallows. A fleeting dugong sighting, the animal's manatee-like form materialising from the murk and disappearing just as quickly, ranks among diving's most special moments.
