MNEMBA'S TOP DIVE SITE: Aquarium

DESTINATION OVERVIEW
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 is measures around 15 square kilometres and to its 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 easy and shallow, there are also a couple of very deep wall dives suitable for advanced divers.

Accommodation and dive operations

PROS AND CONS
Access to Mnemba is by dhoni, the lovely local boats. The atoll is only 30 minutes from the village of Matemwe on the coast. Daily access is affected by tidal changes and you may have to drive up a bumpy track for some distance to be able to cross the shallow coastal reef. Accommodation tends towards the budget/backpacker style. An option is to stay at Mnemba Lodge on the island but it is very expensive.

SCUBA DIVING
The reef’s popularity can make it feel a little crowded at times. However, the diving is easy, currents are avoidable and the visibility is good. This is surprisingly rewarding with a good mix of patch reefs and good corals, interesting critters and occasional encounters with bigger animals.

OPINION
We were extremely surprised by how much we liked diving around this small atoll. The marine life was far more varied than we expected. However, there is a big issue with local fishermen encroaching on designated dive areas and you may well see some upsetting practices. We dived with One Ocean Diving and thought their system, staff and operation were excellent.
