Everything you need to know about this dive site.
Dive Site Overview
Designated a natural park in 2010, the Lighthouse area forms a crucial marine sanctuary around a historic 1908 lighthouse on Nosy Tanikely. Formal protection actively shapes the underwater experience, extending beyond mere administration.
A marine reserve strictly enforces a 700 m / 2,300 ft radius where fishing and night diving are completely prohibited. Such regulations are paramount to the site's ecological integrity. Descending reveals a tapestry of underwater environments: expansive coral formations range from dense gardens in shallower, sunlit zones to intricate reef systems as divers venture deeper.
Divers encounter diverse reef structures, including small bommies and ledges, interspersed with clear sandy-bottom areas where unique macro life often camouflages itself. Shallower sections provide a gentle introduction for novices, yet the reef gradually slopes, offering exploration down to typical recreational depths of approximately 25 m / 82 ft.
This gradient ensures varied profiles for different skill levels. Healthy, undisturbed habitat supports a remarkable array of marine life.
Consistent clarity and conditions emphasize detailed observation of the reef's complex interactions, making for an immersive experience in a well-preserved natural setting.
