Boca de Inferno
A couple of miles south of São Tome you will find Boca de Inferno, Hells mouth. It is a natural phenomenon caused when the waves finds their way in to a narrow ravine that ends in a cave with a hole in the roof. The water is then forced up through the hole and creates a cascade of water that shoots up into the air. It is a very dramatic scene when the big waves hits the black cliffs.
