Mafia Island and its reefs are renown as an excellent,
World-class diving destination.


Scientists have confirmed that Mafia has some of the richest reefs in the World, with an unparalleled variety of hard and soft corals and diversity of tropical fish. We have dived on fabulous sites from Mafia to Kilwa offering shallow to deep reefs of immense beauty and richness, bommies, channels, walls and caves, drift and night dives. These are new sites and we have years of exploration still to do.


through our in-house water sports department – Blue World Diving – offers quality diving services for advanced and novice divers in safety under professional instruction. We are a PADI Five-Star Resort Centre. On all trips we take refreshments, snacks and picnic lunches aboard our dive boats and stay out for two-tank dives.

Adventure dives (night, wall, reef and drift dives) are regular features of an active diving programme. For groups of up to twelve guests a cruise can be planned to take in the marvellous destinations of Ras Mkumbi, Forbes Bay, Kitutia Reef, Okuza and Nyuni Islands and the reef complex surrounding Songo Songo and Njovi islands. These safaris offer superb diving and snorkelling over exquisite coral gardens in excellent visibility, and have rarely been dived. Trained diving assistants handle all equipment, help divers and check their equipment, so that you are free to enjoy the dives and all other activities during each day.


We use the best quality Scubapro and Mares equipment and Faber cylinders and employ rigid safety and maintenance standards. Equipment is well maintained and replaced regularly. We buddy divers carefully to ensure similar standards and interests and all diving is preceded by briefings and checks, to ensure maximum enjoyment. Trained diving assistants handle all equipment, help divers and check their equipment, so that you are free to enjoy the dives and all other activities during each day.

The disturbance or removal of any form of marine life is prohibited and we use boat engines of low horsepower to minimise pollution, and sail the dhow whenever possible. We have been assisting marine research for over twenty-five years and hope that all our guests will benefit from the accumulated knowledge and the conservation programmes underway.


We are indebted to FRONTIER Tanzania for some of the information in the text which follows. Their report on the diving in Mafia - The Guide to the Diving of Mafia Island: an Unexplored Paradise - is in the Kinasi library.

Chole Bay is blessed with a number of excellent dives within the Bay, ensuring diving in almost any weather, as well as easy access. Visibility varies with the wind and tides, and is generally poor on outgoing tides as there is the normal accumulation of organic and granular matter in the water. The diving is tide-dependent for this reason and also to avoid strong currents at the dive sites which are close to the mouth of the Bay (Kinasi Pass). We usually dive on the full low, full high or on the incoming tide for the Kinasi Pass drift dive and the Chole and Kinsai walls. Diving outside the Bay is subject to weather conditions and tides, as it can be dangerous to negotiate Kinasi Pass on an outgoing tide; however, once outside the Bay the dives are not tide dependent.

Almost all Mafia’s best diving is at depths of less than 30m so it is a sport diver’s paradise. The reefs of the archipelago offer a staggeringly beautiful and varied display of marine life. The excellent condition and high diversity of the reefs stimulated the creation of Mafia Island Marine Park, Tanzania’s first marine park. Examples of most kinds of tropical marine habitat occur here, including exposed fringing reefs, rock walls, soft coral and algae-dominated reefs. The diversity of animal and plant life is hard to match, with over 50 genera of corals and 400 species of fish so far identified; many more still await determination. There are excellent examples of giant table corals, delicate sea fans, whip corals, and huge stands of blue-tipped staghorn corals. Large predatory fish and turtles are common and surprisingly unaffected by approaching divers.
