São Tomé and Príncipe lie in the Gulf of Guinea about 150 mi (240 km) off West Afrika. São Tomé (about 330 sq mi; 859 sq km) is covered by a dense mountainous jungle, out of which have been carved large plantations. Príncipe (about 40 sq mi; 142 sq km) consists of jagged mountains. Other islands in the republic are Pedras Tinhosas and Rolas. About 95% of the population lives on São Tomé.
