About Sao Tome and Principe

Sao Tome and Principe is a small island nation in the Gulf of Guinea, with volcanic peaks, rainforest and Portuguese cocoa estates. The capital Sao Tome holds the cathedral and markets, while the north coast beaches, Pico Cao Grande, Obo national park and the smaller island of Principe are the best-known highlights. The drier months from June to September suit hiking and beaches; the rest of the year is wetter, heaviest from March to May, though the islands stay warm.
