Twenty minutes' drive north of Cascais, Cabo da Roca is the westernmost point of continental Europe, a cape of dark schist cliffs falling 140 metres straight down to the Atlantic. The lighthouse — the second oldest in Portugal, dating from 1772 — still functions, and there is a small visitor centre and café in the cluster of buildings around it.
It is windy, often misty, and almost always cold by Lisbon standards, but the dramatic view of the cliff line stretching south toward Cascais is hard to beat. Tour buses can fill the small parking area at midday; come early morning or late afternoon if you can. Bus 403 runs from Cascais via Sintra all year.
