Aerial view of Mnemba Island with dazzling turquoise waters, white sand beaches, and coral reefs off Zanzibar, Tanzania.
Mnemba Atoll is a protected coral reef system off Zanzibar's northeast coast, surrounding the privately owned Mnemba Island. The atoll is internationally recognised for its exceptionally clear water, extensive coral gardens and diverse marine life, making it one of the Indian Ocean's most important marine conservation areas. Although visitors cannot land on the island itself, the surrounding reefs are accessible by boat for snorkelling and diving. The combination of tropical reefs, clear lagoons and open ocean scenery makes Mnemba Atoll one of Zanzibar's defining coastal destinations.
