(CNN) — Often referred to as the "Spice Islands", the archipelago of Zanzibar is made up of a necklace of islands that bead their way down the shore of East Africa, off the coast of Tanzania.

There's the main island, which has a UNESCO World Heritage Site for its capital, sister island Pemba, with its extensive clove plantations and the neighboring Mafia Archipelago, known for its majestic coral reefs and whale sharks.
