Landscape
Portugal’s mainland has Atlantic-facing coasts, northern uplands and generally lower southern terrain. Major rivers cut westward toward the ocean. Interior valleys and plateaus differ from the more strongly maritime coastal belt.
The Douro Valley is a deeply incised river landscape with cultivated slopes. The Algarve includes limestone cliffs, coves and beaches. Portugal also includes the volcanic Azores and Madeira archipelagos, whose island geography differs from that of the mainland.
