ZANZIBAR, TANZANIA & KENYA DIVE RESORTS/LIVEABOARDS

While a small number of private charter liveaboards are available, the majority of diving is shore-based or from day-boats.

INTRO TO ZANZIBAR, TANZANIA & KENYA

Located on the east coast of equatorial Africa, the islands of Zanzibar and Pemba, along with Mafia Island to the south are the central hub of diving in Tanzania. Also known as the Spice Islands, these three dive locations offer a wealth of tropical reef diving, some reasonable macro, and unexpected encounters with larger pelagic species migrating along Africa’s Indian Ocean coastline. The Spice Islands also offer a wealth of historic, cultural, and wildlife experiences, and are a fantastic family or group travel destination full of exotic discoveries. 

Diving along Tanzania’s mainland coast is also possible, with a range of sites from the northern border with Kenya, through Bagamoyo, Dar es Salaam, and Kilwa, as far south as Mtwara. While the northern stretches of coastline offer typical Indian Ocean diving, the southern reaches near the border with Mozambique are relatively unexplored, with a dramatic coastline, deep trenches, and diversifying ocean currents creating an excitingly wild environment ripe for discovery.

Finally, no visit to Tanzania would be complete without a dive or two in Lake Tanganyika. Famous for its collection of freshwater cichlids, this is a unique experience that is ideally combined with a land safari or trip to the country’s interior.

Venturing north of Tanzania, Kenya’s diving coastline boasts four protected marine parks and six marine reserves harboring a wealth of beautiful reefs, tropical fish species, and interesting topography to suit all diving abilities. The protected status of these areas makes for some excellent reef diving with large corals in very good condition and an abundance of marine life, big and small.

MARINE LIFE & PHOTOGRAPHY SUBJECTS

Scuba divers exploring Zanzibar, Tanzania, and Kenya will have access to the full catalog of tropical Indian Ocean species throughout the region’s balmy waters. A myriad of reef fish adorns the inshore reef sites, with ribbon eels, fire dartfish, octopus, moray eels, and giant groupers commonplace. Many larger species also patrol the inner reef walls and barracuda, yellowfin tuna, and large schools of trevally are not an uncommon sight in the blue. Reef sharks and dolphins can be spotted year-round, as can the manta rays in Kisite Marine Reserve.

Mafia Island offers a resident population of whale sharks, as well as remarkably good fish life, and green sea and hawksbill turtles, with the opportunity to witness turtle hatchings at certain times of year.

A good number of ocean visitors pass through the Spice Islands and along the coast of Tanzania and Kenya on their seasonal migrations. Whale sharks can be spotted between October and April, but are most common in November and December, and this is also the season for humpback whale sightings. Although far less common, hammerhead sharks can sometimes be seen along the outermost reefs in the winter months.

For a unique experience, divers can visit Lake Tanganyika and dive with almost 250 different species of endemic cichlid fish. It is believed that 98% of these fish are unique to the lake.

Kenya’s coastline is known for its diverse collection of nudibranchs and opisthobranchs, including some rare species and color variations unique to this part of the Indian Ocean. It is also common to find large scorpionfish and stonefish along the reefs, as well as shrimps, lobster, and various other crustaceans.

• Famous for shark encounters, divers can expect to spot whitetip, silvertip, gray whaler, and even the occasional hammerhead shark along coral festooned walls dressed in huge gorgonians.
• Pemba Channel, Pemba Island
• Off the west coast of Pemba Island, the shallow reef plunges thousands of feet into the Pemba Channel and a series of pinnacles and steep walls create a habitat for a variety of interesting marine life. Reef sharks, turtles, Napoleon wrasse, and other pelagic gamefish frequent the strong currents of the channel, but despite the excellent visibility, this site is best suited to experienced divers.
• Misali Island Coral Garden, Pemba Island
• A Marine Conservation Area home to remarkable species diversity including 350 species of fish and over 40 varieties of coral, Misali is a true diving paradise in East Africa. Extensive and beautifully vibrant coral reefs support a plethora of reef fish species small and large, as well as endangered turtles and larger marine creatures.

Whale sharks are often spotted passing through between October and February. The Canyon is an excellent all-round site boasting a soft coral covered arch teeming with snapper and trevallies. 
• Kisite Mpunguti Marine Reserve, Kenya
• Arguably the most beautiful destination on Kenya’s coast, much of the diving centers around Wasini Island, with 10 sites both inside and outside the park offering great year-round diving. Over 40 varieties of coral and 250 species of fish have been documented here so far, with the star of the show the huge manta rays. Strong currents at Nyulli Reef promote drift dives through a blur of snapper, barracuda, and sightings of the rare zebra shark, while the chilled-out and shallow Kisite Point offers up encounters with turtles and bottlenose dolphins.

The overhangs and outer reefs of Mtwapa are an exciting dive featuring large grouper and the occasional whale shark, while the MV Dania is a purposely scuttled wreck in 115ft (35m) of water with some reasonable penetration opportunities. The Vuma Caves near Kilifi Creek are accessed via sea caves at 65ft (20m) and exited through a 32ft (10m) chimney in the reef above. The caves are a hideaway for eels, barracuda, and grouper, and the entrance is often frequented by dolphins.
