Manta Point (Nosy Be)
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
Local operators run a deeper offshore bank west of Nosy Be under the name Manta Point, dived mainly in the spring season when plankton draws big filter feeders to the area. Mantas visit its cleaning stations, though far less predictably than at famous stations elsewhere in this ocean — this is a hopeful dive rather than a scheduled appointment, and honest shops sell it that way. The bank itself holds reef sharks on some days, passing eagle rays, and solid fish life over the coral heads. Details in print about the site are thin; treat depths and conditions as the operator briefs them.
The moment you come for: Seasonal chance of mantas at an offshore cleaning bank
Topography: Offshore reef bank with cleaning-station coral heads
Current: An exposed outer bank; operators time it around the calmer dry-season windows.
Know before you splash
Hazards: Open-water exposure and current on the bank.
Conservation: Standard manta-station etiquette applies on the days it pays off: low, still, and out of the animals' lane.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
