The Boca do Inferno is an interesting cliff formation close to Cascais, which translates as Hell’s Mouth.
The Atlantic Ocean relentlessly smashing on the cliffs has chiseled out a small cave, which subsequently collapsed forming a small bay and natural arch.
Hell’s Mouth gets its name from the booming of the ocean waves which crash against the cliff face, forcing their way into a cave system, and spraying angrily from an opening above.
When the sea is calm you’ll wonder what the fuss is about but we were lucky enough to see it in full spate!
Beautiful photos!
