Zanzibar is a 650-square-mile island about 25 miles off the Tanzanian coast, a short 20-minute flight from the capital Dar es Salaam. Renowned for its beautiful sandy beaches and coral reefs, visitors often spend some time relaxing in one of the many luxury resorts or boutique hotels to round off their safari itinerary while enjoying some of the many water sports on offer, including scuba diving, snorkelling and deep sea fishing, as well as the opportunity to sail in a traditional local dhow. The old city of Stone Town is the cultural heart of the island with its winding alleys, bustling bazaars, mosques and grand Arab houses, and in the year 2000 became listed as a UNESCO World Heritage Site.
