Manta Reef
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.
Manta Reef is the site that put Tofo on the scientific map — the cleaning stations here supplied much of the fieldwork behind the recognition of reef and oceanic mantas as separate species. Divers settle along the rock while mantas bank over the pinnacles, gills flared for the cleaner wrasse; both manta species visit, and the oceanics can span well over four meters. Smalleye stingrays, morays, potato bass, and thick winter baitfish fill the gaps between passes. Sightings have thinned since the mid-2000s and no dive is guaranteed — but when a big animal arrives at 24 meters in green Mozambican water, it feels earned.
The moment you come for: Historic manta cleaning stations visited by both manta species
Topography: Rocky reef plateau with cleaning-station pinnacles, gullies, and sand breaks
Current: Open-coast site reached by a long surf launch; current and surge track the swell.
Know before you splash
Hazards: Depth, surge, surf launches, and a long boat ride down an exposed coast.
Conservation: Stay low and behind the station line; a blocked cleaning station is an abandoned one. Sighting data feeds long-running local research.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
