Kichwani
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.
Kichwani is the Mnemba conservation area's showpiece slope: a wall-like bank of hard coral that begins in three meters of turquoise and drops in steps toward thirty. Green turtles graze the shallows in numbers that make counting pointless, moray heads punctuate the coral, and the mid-slope is a continuous drift of snapper, fusiliers, and anthias. Deeper, whitetip reef sharks rest under overhangs and the coral thins to sponge and whip growth. Currents stay gentle enough for newer divers on most tides while the slope's depth range keeps experienced buddies interested — the balance that made Mnemba famous.
The moment you come for: Turtle-dense shallows; stepped coral slope from snorkel depth to 30 meters
Topography: Steep coral slope on Mnemba's southwestern side, shelving from lagoon sand into blue water
Current: Gentle tidal drift along the slope; occasionally brisker on spring tides.
Know before you splash
Hazards: Boat traffic in the busy season; mild drift separation risk for snorkelers.
Permits & rules: Conservation-area fee collected per visit through operators.
Conservation: Inside the Mnemba conservation area — entry fees fund patrols, and touching reef or turtles is prohibited.
Nitrox: Worth it here — profiles sit in the range where enriched air meaningfully extends no-stop time (with the training to use it).
