About Diving in Zanzibar

Zanzibar features a variety of unique marine spectacles in East Africa. The magnificent aquatic paradise is perfect for scuba diving and a wide range of water activities including snorkeling. Diving at Mnemba Atoll is one of the most exciting things to do in Zanzibar.

The Mnemba Atoll Marine Park boasts an array of colourful reef fishes as well as other tropical species. Scuba diving in Zanzibar is good all through the year. However, the best time to go diving on the island is during the rainy season when the ocean is crystal-clear and calm.
