A small coral island off the north-east coast of Zanzibar, ringed by a protected reef and best known for snorkelling, diving and sea turtles.
Mnemba Island is a tiny, uninhabited island a short boat ride off Matemwe on Zanzibar’s north-east coast. The surrounding Mnemba Atoll is a marine conservation area with clear, shallow water, healthy coral and some of the best snorkelling and diving in Tanzania. It is a popular beach extension after a northern Tanzania safari because the contrast is complete: from dust, vehicles and early starts to turquoise water and barefoot days.
This page is part of our beach-extension coverage for Tanzania safaris. Mnemba itself is not a safari destination, but it works well as the closing chapter of one.
Quick FactsAbout 2 kilometres off the north-east coast of Zanzibar (Unguja), opposite Matemwe.
Boat transfers from the mainland beaches. The island itself has a single private lodge, and landing on the island is generally limited to its guests.
Snorkelling, scuba diving, dolphin and turtle encounters, and a quiet beach finish to a safari.
June to October and December to February are drier and sunnier; the long rains run roughly March to May.
The reef around Mnemba is the main attraction. The water is warm and often very clear, and the reef supports a wide range of colourful tropical fish, with the chance of green and hawksbill turtles. Many day trips from Matemwe, Kiwengwa and Nungwi include a snorkelling stop at the atoll; certified divers can dive deeper sites on the walls and slopes. Conditions depend on tides, wind and season, so always book with a licensed operator and ask about current visibility.
Early morning boat trips often combine reef snorkelling with the chance to see dolphins. Wildlife viewing at sea is never guaranteed, and responsible operators keep their distance and limit swimming with dolphins to avoid stressing the animals. Turtles nest on Zanzibar’s beaches at certain times of year, and Mnemba has long been a nesting site, so it is a protected habitat in which guests are expected to follow conservation rules.
There are two ways to experience Mnemba. First, a day trip: a boat from your hotel on the north-east coast takes you to the atoll to snorkel, usually without landing on the island. Second, an island stay: a very small, exclusive lodge occupies the island, available to guests only. The latter is a high-end option, and prices vary widely, so we always confirm current rates and conditions when planning. Which suits you depends on your budget and how much you want of the coast.
The classic sequence is a northern circuit safari followed by a flight from Kilimanjaro or Arusha to Zanzibar, then a few days on the coast. Our 9-day Tanzania Bush and Beach safari follows exactly this pattern, and our Zanzibar page explains the wider island, including Stone Town. Kenya offers a similar coast at Diani Beach.
Zanzibar is conservative, mostly Muslim, and respectful dress away from the beach is appreciated. Sun is strong, so use reef-safe sunscreen and a rash vest, and do not touch or stand on coral. Check our health and safety notes and entry requirements before you travel.
Matemwe and Kigomani are the closest villages to Mnemba, with a string of beach lodges from simple to very high-end. Further south, Pwani Mchangani and Kiwengwa have larger resorts. Pick a base for the character you prefer: small, quiet and barefoot, or larger with more facilities. Tides matter on this coast, and at low tide the sea retreats a long way, so many guests plan swims and boat trips around the tide table.
Mnemba’s reef is fragile. Avoid touching coral, never feed fish, keep sunscreen to reef-safe products, and follow the instructions of your boat crew about distance from turtles and dolphins. Marine park fees help pay for patrols and monitoring, and choosing operators who respect these rules directly protects the place you came to see.
