The island of Zanzibar lies off the Tanzania coastline and is a unique mix of history, culture and natural beauty. There are dive sites all the way around the island but the Mnemba Atoll, which lies off the northern tip of the island and in the channel that separates Zanzibar from Pemba island, attracts the majority of divers.
The pear-shaped atoll measures around 15 square kilometres and to one side is tiny, pretty Mnemba island. This area is regarded as a conservation zone and is a charming spot with some impressive marine life. Although the reefs are not enormous they are home to a wide array of animals from the tiniest of shrimp to huge turtles. Two very rarely seen animals are easily found here – the outrageously patterned dragon moray eel and the world's largest nudibranch, the Djibouti Spanish Dancer.
While most dives are relaxing, easy and shallow, there are also a couple of very deep wall dives suitable for advanced divers.
