Lagos is a town in southern Portugal's Algarve region. It’s known for its walled old town, cliffs and Atlantic beaches. Steep wooden steps lead to the sandy cove of Praia do Camilo. Nearby Ponta de Piedade offers sweeping headland views and a clifftop lighthouse. The ornate 18th-century church of Igreja de Santo António sits across from the Castelo dos Governadores, a castle with a baroque facade and watchtowers.
