Boca do Inferno, Cascais

The Boca do Inferno is a unique sea-arch and cliff formation close to the town of Cascais.

As a visitor this is a dramatic section of coastline for you to visit, with giant waves smashing into the cliffs and high-tide waves roaring through the arch into the base of the chasm. At the Boca do Inferno is a seaward viewing platform, a decent seafood restaurant and a selection of handicraft tourists stalls.

The ideal time to visit the Boca do Inferno is at sunset, and watch the sun sink below the ocean horizon and illuminate the sky in orange glows – magical.

Formation of the Boca do Inferno

The Boca do Inferno was formed by the erosion of a weak vein of limestone in the cliff face. This initially led to a cave being excavated which slowly expanded over the generations. The tougher outer rock remained while the weaker rock was eroded to such a stage that the roof of the cave collapsed forming the unique Boca do Inferno.

In 1930 Aleister Crowley a magician, astrologer and mystic, faked his own death at the Boca do Inferno Cascais. As part of the stunt, he secretly left Portugal to reappeared three weeks later at an exhibition of his work in Berlin.
