Ilha de Moçambique, Mozambique

Population: 54,315

Why you should go: The island, which is a World Heritage Site since 1991, was the capital of colonial Portuguese East Africa until 1898. Apart from trips to Chocas Beach and diving/snorkeling activities, you can visit Chapel of Nossa Senhora, an old Portuguese fort and Palace of São Paulo museum (pictured).
