Chole Reef South is a shallow, coral-rich bank reef in Mafia Island.
Chole Reef South is a shallow Chole Bay bank reef with a coral-rich top and a sand-and-rubble finish. It suits easy-paced scuba, freediving, and snorkeling because the best sightings come from the reef edge and the shallower coral. Keep a patient pace for dense fish life, turtles, triggerfish, rays, and plenty of small critters.
Site Conditions
Safety Notes
Give titan triggerfish room on the rubble edge and keep buoyancy tight over the coral bank.
Access Restrictions

Legal Notes
Mafia Island Marine Park rules apply, and dive scheduling is tide dependent.
Community notes to help plan your visit.
Scuba Diving
A relaxed reef dive that stays shallow enough for easy navigation, with the reef edge and rubble zone rewarding patient search and good buoyancy.
Freediving
The shallow bank makes this a comfortable freedive option in calm water, but it still rewards slow, deliberate sessions rather than pushing depth.
Snorkeling
The shallow top of the bank makes this one of the easier Chole Bay snorkeling options when the water is calm.
