Mnemba Atoll

Beautiful small exclusive island

Mnemba Atoll is a beautiful small exclusive island, surrounded by colorful reefs.

This conservation area is a magnet for divers and snorkelers who enjoy swimming in the turquoise waters, famous for its healthy fish life. The tropical reefs in the South part of the island offer gradual and steeper slopes and stretched reefs with impressive plate corals. It is the home of green turtles, playful bottlenose dolphins, giant groupers, barracuda, moray eels, stingrays, and kingfish.

Macro-lovers will love the dragon moray eels, leaf fish, nudibranch, flatworms, seagrass and ornate ghost pipefish, and seahorses. In the North-East part, there are steep and deep wall dives suitable for experienced divers. They often start around 30 meters in-depth and offer more pelagic species, like jacks, batfish, barracuda, and the occasional shark.

With great visibility and a variety of dive sites, Mnemba has something to offer for everybody and is the best place for diving and snorkeling in Zanzibar. In August and September, we encounter migrating humpback whales.
