In the clear blue Indian Ocean waters, large napoleon wrasse swim side by side with pelagics such as tuna, jacks, wahoo and schools of barracuda. Manta and eagle rays cruise the edge of the reefs along with many species of shark and giant groupers. Hawksbill and green turtles roam the top of the reefs for food, rest and shelter, while many smaller reef fish are playing in the shallower depths. Between crustaceans, brightly colored starfish can be found in a setting of vibrant colors from the surrounding beautiful coral and sponges.

The best diving is found around the islands of Pemba, Zanzibar and Mafia. Both landbased and liveaboard operators ply much of these waters.

Pemba Island is remote, relatively unknown and on many experts list of top dive spots in the world. It is surrounded by numerous small islands, fringed by beautiful coral reefs and plunging drop-offs which gives a deep blue color to the ocean that gradually turns into the turquoise waters of the shallows.

Mostly the western coast has been explored for diving as this side is sheltered and closest to the main land. The shallows around the islands offer stunning snorkelling and excellent conditions to experience lush coral gardens which stretches as far a the eye can see.
