The Mafia Island archipelago off the coast of Tanzania offers terrific snorkeling. And with tourist hot spots like Zanzibar and the Comoros Islands, the coastline has long been a favorite of intrepid sailors and cruise ships alike. In January 2011, pirates chased the Zanzibar-bound Spirit of Adventure during a black-tie dinner, and all 348 passengers sought safety below deck. Fortunately, the boat outran the pirates and the passengers returned home safely.
