Dive in Mafia Island, Tanzania's Best Kept Secret!

Why We Love It

Imagine a breathtaking island with a lush green interior, white-sand beaches, and crystal-clear waters filled with beautiful coral reefs: this is Mafia Island, also known for its whale sharks! Located 160 km south of Zanzibar, Mafia Island hosts some of the most diverse marine life in Eastern Africa, with over 50 types of corals and 400 species of fish. The island is also one of the planet's growing hot spots for whale shark sightings, with WWF registering not fewer than 180 individuals in December 2017!


The dive center runs regular beach clean-ups and Project AWARE Dive Against Debris events. They also run a patrol boat every day in conjunction with the Mafia Island Marine Park.

Who Is It For?

For divers who want to escape the crowds, this is a perfect destination. Snorkelers will be delighted by the shallow coral reefs and the chance to snorkel with whale sharks. Non-diving partners can go on excursions to see 10th and 12th century ruins, explore stunning sandbanks, and witness turtle hatching in season.
