Known as the spice island, the beautiful island of Zanzibar on Africa’s East coast is bursting with culture and history, seemingly at odds with its idyllic geography of white-sand beaches with palms swaying lazily in the sea breeze. Together this makes Zanzibar a fabulous place to explore as well as a dream to relax and unwind. Zanzibar is the semi-autonomous part of Tanzania in East Africa. It is composed of the Zanzibar Archipelago in the Indian Ocean, 25–50 kilometres (16–31 mi) off the coast of the mainland, and consist of many small islands and two large ones: Unguja (the main island, referred to informally as Zanzibar) and Pemba. The capital is Zanzibar City, located on the island of Unguja. Its historic centre is Stone Town, which is a World Heritage Site.
