The higher reaches of the Douro are known for their harsh terrain, with baking hot summers and cold winters. Yet this apparently inhospitable region was home to a prehistoric people whose rock engravings, fully mapped only in the 1990s, may now be visited with a guide. This region is also known for the delicate oil made from olives grown here, and for almonds, which in the town of Torre de Moncorvo are traditionally toasted with sugar.
