Zanzibar is the classic beach finale to a Tanzania safari — a Swahili-Arab island steeped in centuries of trading history, with the UNESCO-listed Stone Town at its historic heart.
Beyond Stone Town's winding alleys and carved doors, the island is ringed with powder-white sand and warm, turquoise water, and its interior is covered in fragrant clove, nutmeg and vanilla plantations that can be explored on a spice tour.
Snorkeling and diving on nearby reefs, sunset dhow cruises, and swimming with dolphins off the southern coast round out a classic Zanzibar itinerary.
June–October and December–February are driest and sunniest; avoid the long rains in April and May if possible.
