At Boca do Inferno, Atlantic waves surge into a sea-carved chasm beneath pale limestone cliffs.
Citadel and historic centre
The Cidadela de Cascais grew around the coastal fortress of Nossa Senhora da Luz, guarding the entrance to the Tagus estuary. The former military complex now frames a walk through the old centre, where the Condes de Castro Guimarães Museum occupies a fanciful early-20th-century residence beside the sea.
Boca do Inferno
A short coastal route reaches Boca do Inferno, a sea-carved chasm and rock arch just west of the centre. Atlantic waves surge into the opening, exposing the limestone cliffs and making the town’s maritime setting tangible.
