The island of Unguja, part of Zanzibar, makes up the final Spice Island. Once part of the British Empire, today Zanzibar is a semi-autonomous region of Tanzania. The African island has been for centuries an important trading center, a melting pot of African, Indian and Arab influences. Zanzibar’s major tourist attraction is Stone Town, with its whitewashed coral rag houses. Another big draw are its beautiful white sandy beaches.
