Mafia Island Diving in Chole Bay

Mafia Island diving is best known for the spectacular reefs of Chole Bay, one of East Africa’s most diverse marine environments. Protected by the Mafia Island Marine Park, these reefs are home to colourful hard and soft corals, turtles, moray eels, reef sharks, octopuses, rays, and hundreds of tropical fish species.

The calm, sheltered waters make  Island diving suitable for photographers, beginner divers, and experienced enthusiasts alike. Visibility often exceeds 20 metres during favourable conditions, allowing divers to appreciate the remarkable health of the reef ecosystem. Marine conservation regulations have helped preserve these underwater habitats, making Mafia Island diving one of the most rewarding experiences on Tanzania’s coastline.

Many guests continue their coastal holiday with the Best of Zanzibar itinerary or enjoy a relaxing Short Zanzibar escape after completing their diving adventure.
