The Spice Islands are very close to the mainland, and consist of several small islands and two large ones: Unguja ( Zanzibar), and Pemba. The capital of Zanzibar, located on the island of Unguja, is Zanzibar City, and its historic centre, known as Stone Town, is a World Heritage Site. Zanzibar’s main industries are spices, raffia, and tourism. The production of cloves, nutmeg, cinnamon and pepper are common, it is for this reason that the islands are sometimes called the Spice Islands. Visitors enjoy Zanzibar for relaxing at the end of a safari, the laid back environment of Stonetown, and the snorkling, diving and fresh sea food all make for a fitting end to any safari.
