São Tomé and Príncipe

The islands of São Tomé and Príncipe, situated in the equatorial Atlantic and Gulf of Guinea about 300 and 250 kilometres (190 and 160 mi), respectively, off the northwest coast of Gabon, constitute Africa’s second smallest country. Both are part of the Cameroon volcanic mountain line, which also includes the islands of Annobón to the southwest, Bioko to the northeast (both part of Equatorial Guinea), and Mount Cameroon on the coast of Gulf of Guinea. Pico de São Tomé

São Tomé is 50 km (30 mi) long and 30 km (20 mi) wide and the more mountainous of the two islands. Its peaks reach 2,024 m (6,640 ft) – Pico de São Tomé. Príncipe is about 30 km (20 mi) long and 6 km (4 mi) wide. Its peaks reach 948 m (3,110 ft) – Pico de Príncipe. Swift streams radiating down the mountains through lush forest and cropland to the sea cross both islands. The equator lies immediately south of São Tomé Island, passing through an islet Ilhéu das Rolas.

The Pico Cão Grande (Great Dog Peak) is a landmark volcanic plug peak, located at 0°7?0?N 6°34?00?E in southern São Tomé. It rises dramatically over 300 m (1,000 ft) above the surrounding terrain and the summit is 663 m (2,175 ft) above sea level.
