Behind you the plateau stretches away in pale highland grass, sometimes white with frost. Below your feet the land simply ends, dropping away in cliffs, and a thin gray ribbon of asphalt is stitched down the face of it in switchback after switchback. This is the Serra do Rio do Rastro, the escarpment where the coastal lowlands of Santa Catarina rear up into the southern highlands, and the road draped across it is one of the most theatrical drives in Brazil.
