Zanzibar is the Indian Ocean reward at the end of a Tanzanian safari, a spice island of turquoise water and powder-white sand that turns a wildlife trip into a proper holiday. The northern beaches of Nungwi and Kendwa are the family favorites, with soft sand and calm, shallow water for young swimmers, while a boat out to the Mnemba Atoll delivers some of the finest snorkeling in the region and reliable dolphin sightings. After days of dawn game drives on the mainland, the island's slow, warm-water rhythm is exactly the reset a family needs.

Zanzibar is far more than a beach, though. Stone Town, its historic heart, is a maze of narrow lanes, markets, and carved doors, with the Old Fort and the Sultan's Palace to explore and a sunset dhow cruise that quietly becomes the trip's highlight. In Jozani Forest, kids track the rare red colobus monkey, the ethical Cheetah's Rock introduces rescued animals and conservation, and the island's famous spice farms turn a tour into a tasting of cloves, vanilla, and just-picked tropical fruit. The accommodation runs from luxury beachfront resorts with kids' clubs and pools to boutique eco-lodges and private villas, many with family suites and babysitting. Pair it with a safari and Zanzibar gives a family the dream East African one-two, the great migration one week and a barefoot island the next.
