Zanzibar is an island in the Indian Ocean, part of Tanzania, known for its white sandy beaches, turquoise water and the historic Stone Town. Once a centre of the spice trade, the island is still known as the spice island, with a blend of African, Arab and Indian influences. Beyond beaches, it offers sailing trips and a rich marine world. For Macedonian travellers Zanzibar is a distant destination, reached by a longer flight. The climate is tropical, with a warm sea and high temperatures throughout the year, and the calmer, drier periods are well suited to a visit during our winter.
