São Tomé and Príncipe is Africa's second-smallest country and one of its best-kept secrets. These volcanic islands straddle the equator in the Gulf of Guinea, 250 km off Gabon. The larger island of São Tomé features dramatic peaks, rainforest, and golden beaches. Príncipe, a UNESCO Biosphere Reserve with just 8,000 inhabitants, includes Praia Banana—ranked among the world's most beautiful beaches. Portuguese is the language, and the historic roças (plantation estates) produce exceptional single-origin chocolate.
