São Tomé is the larger of the two islands in the Gulf of Guinea, and shares its name with both the national capital and the highest peak. It sits almost exactly on the equator, which makes the light here extraordinary — everything is sharp and green.
The capital, also called São Tomé, holds the main sights. The Sé Cathedral is the oldest cathedral in sub-Saharan Africa, a modest Portuguese colonial building that has survived remarkably well. The São Sebastião Museum inside the old Forte de São Sebastião covers the island's history from the sugar trade to the cocoa era — and the fort itself, with its lighthouse still active on Ana Chaves Bay, is the finest colonial structure in the country.
About 15 km from town, the Obo National Park covers the southern highlands in primary rainforest, home to 28 endemic bird species. The beaches are excellent and largely uncrowded — the best are at Praia das Pombas on the northern coast.
The island's other great draw is its cocoa. Once the world's largest cocoa producer, São Tomé still grows some of the finest beans on earth. Artisan chocolate made from estate-grown Santomean cacao is one of the best things to take home.
