Lamu Island, Kenya (Pop.: 2,000-plus)

Once a center for the slave trade, Lamu has since become a tourist destination — in large part to it being mentioned on the World Heritage List as "the oldest and best-preserved Swahili settlement in East Africa." As no vehicles are allowed, the most popular means of transportation is donkey. In fact, there are some 2,000-3,000 working donkeys on the island.
