Turquoise water. Coral reefs. Ancient island culture.

The Indian Ocean off Tanzania's coast changes colour in every direction. Zanzibar's lagoons shift from turquoise to deep cobalt as the reef falls away. Pemba Island's walls drop into the blue. Mafia Island's marine park protects coral gardens where whale sharks arrive every year between October and March.

But the islands are not only about the water. Stone Town, Zanzibar's medieval heart, is a UNESCO World Heritage city, a labyrinth of coral-stone alleys, carved wooden doors, and centuries of Swahili, Arab, and Persian culture layered upon each other.

Mboka designs island itineraries that balance the beach and the cultural depth. A private villa on the north coast for swimming and diving. Two nights in a boutique Stone Town riad. A sunset dhow cruise to the sandbanks.
