Zanzibar, a semi-autonomous archipelago off Tanzania’s coast in the Indian Ocean, is famed for its spice trade history, turquoise waters, and Swahili culture. Its main islands, Unguja (often called Zanzibar Island) and Pemba, feature Stone Town, a UNESCO-listed historic center with winding alleys, coral stone buildings, and Arab, Indian, and European influences. Once a hub for cloves and a sultanate, Zanzibar now thrives on tourism and fishing, blending its rich past—marked by Omani rule and British colonialism—with a laid-back beach vibe.
