Mnemba Island

Island Private island off Zanzibar known for coral reefs

A coral atoll off northeast Zanzibar, Mnemba Island is a privately managed marine reserve sought for snorkeling, diving with turtles and reef fish, and exclusive beach lodging.

Mnemba Island is a small privately owned island off the northeast coast of Unguja in the Zanzibar archipelago, Tanzania. It is best known for its surrounding coral reef and clear waters that make it a popular site for snorkelling and scuba diving.

The island is ringed by a shallow reef that supports abundant fish life and sea turtles, and the marine area around Mnemba is managed for conservation and tourism. A single small lodge operates on the island and visitor access is typically organised through that facility, making the island a high-end, limited-capacity destination.

Historically the island has been used for marine tourism and conservation; the reef and nearshore waters are important both for local biodiversity and for visitor diving/snorkelling activities.

Mnemba lies off the northeast coast of Unguja (Zanzibar) and is approached by boat from coastal villages on the main island.

Marine life: The island is ringed by a coral reef that supports snorkeling and diving and is noted for sightings of green turtles and diverse reef life.
Access: The landmass is privately owned and hosts an exclusive lodge; access is generally limited to registered guests and organised tours.

Many visitors come as guests of private lodges or liveaboard dive operators that include the transfer. Boats typically take 30-60 minutes from the northeast Unguja shore depending on sea conditions.
