Zanzibar is an island off the Indian Coast of Tanzania and averages only five rainy days for the month of January. The south of the main island offers the best diving conditions while the north has the best sunset views. For exceptional reef diving and snorkeling, head to the exclusive outlying islands of Pemba, Mafia and Mnemba. Zanzibar is also home to Stone Town, a World Heritage Site with plenty to see and do. A beach holiday on Zanzibar is the perfect way to relax after the early morning wake-up calls of a Southern Serengeti safari.
