Diving sites around Zanzibar

The diving sites around Zanzibar are divine.

The coral reefs surrounding Zanzibar are home to a over 400 different types of reef fish, turtles, dolphins, and other marine life. Humpback whales migrate from July to October. The inviting Indian Ocean surrounding Zanzibar has an average water temperature is 27°C and visibility of 10 – 40 metres.

Zanzibar is a paradise for everyone: the macro life lovers, underwater photographers, adventurers, beginning divers, snorkelers… Watch the green turtles cruise the current of the ocean, or the dolphins play in the azure waters surrounding the boat, or the small colourful nudibranchs on a beautiful variety of corals.

Whether you are looking to make fun dives on some of the beautiful dive sites around the island, or become a (more experienced) diver with our array of diving courses, or take a snorkeling trip to see Zanzibar’s underwater world from the surface – you will be amazed!

We also try to give a little back to the beautiful oceans, by organizing Clean up Dives as much as we can! You will dive for free while helping us clean the reef from all kinds of debris. Ask us when the next dive will be and help us save the oceans – one dive at a time! All the items we collect are registered on the website of Project AWARE, to help them gather information to tackle the issue of marine debris.

On the east coast of Zanzibar, East Africa, lies the idyllic Mnemba island. This small, privately owned island is surrounded by a large circular reef, perfect site for scuba diving. In the clear turquoise waters surrounding this marine conservation area, a great diversity of marine life can be seen. Bottle-nose dolphins often visit the waters around the island and green turtles lay their eggs on its white beaches. From July till September, humpback whales cruise through the waters near Mnemba island. There are many beautiful diving sites around Mnemba and it is a popular area for both scuba diving and snorkeling.
