Farol de São Vicente
The views from outside this lighthouse are remarkable, and the beacon is said to have the strongest reflectors in Europe—they cast a beam 96 km (60 miles) out to sea. Turquoise water whips across the base of the rust-color cliffs below; the fortress at Sagres is visible to the east; and in the distance lies the immense Atlantic. There's a small museum and café on-site if you want to linger.
