City

Zanzibar's UNESCO-listed old town, a maze of coral-stone buildings and carved doors built on centuries of spice, ivory and slave trade.

Eleven monolithic churches carved downward into volcanic rock in the twelfth and thirteenth centuries, still active places of worship today.

Zanzibar's two main beach towns on the island's northern tip, Nungwi lively and tide-affected, Kendwa quieter with swimmable water throughout the day.
