Diving in Zanzibar

Zanzibar is a cluster of islands that make up a region of Tanzania with a semi-autonomous government. They are located anywhere from 25 to 50 kilometers (16 to 31 miles) off the coast of mainland Tanzania. While this archipelago has many small islands that help form it, the two main islands are Unguja and Pemba Island.

Unguja is the larger of the two islands and the capital of the area. It is this island that is generally referred to as Zanzibar even though that is actually a term for the whole region.

Diving here is all about exploring the dazzling coral reefs, filled with colorful fish and around 500 marine species in total. There are sandy atolls where you can dive and snorkel from the shore, dramatic walls and historic wrecks as well as deep dives with amazing macro from the more advanced divers. Expect crystalline waters of a brilliant blue, big game fish and even dolphins and turtles from time to time with whale sharks passing through the area between September and December. You’ll need to be aware of the currents at some sites and keep safety in mind and remember there are two rainy seasons, October/November and April to June.

Before diving, please confirm that diving is permitted at your chosen location, and comply with all relevant local laws, regulations, and posted signage. The responsibility for verifying the legality of the dive and assessing any associated risks rests entirely with you.
