Official tourism overview of Nosy Sakatia as a protected, quiet island near Nosy Be.
Arch-rich Nosy Be boat dive with macro and pelagic chances.
Arch-rich Nosy Be boat dive with macro and pelagic chances.
The dive is normally arranged through a Nosy Be operator with local knowledge of tide and weather.
Les Arches de Sakatia is a Nosy Be boat dive built around a compact rock formation with three arches, a smaller arch farther out, and a shallower plateau after the arches. The site mixes structure and open water, so it suits careful navigation, buoyancy control, and macro searching. White tip sharks and manta rays are possible, but the real payoff is the mix of arches, camouflaged fish, and clean photo shapes on a protected island day trip.

Scuba Diving
A structure dive with arches, a nearby secondary arch, and a plateau that rewards careful trim and slow searching.
Freediving
More of a scuba site than a freedive target because the useful structure is deeper and the arches reward controlled positioning.
Snorkeling
Limited snorkeling value; the main arches and photo features sit below easy surface range.
