Located on Costa da Guia, west of the town of Cascais, Avenida Rei Humberto II de Itália, city of Cascais, District of Lisbon, Central Portugal
The name "Boca do Inferno" given to this place is due to the morphological analogy and the tremendous and frightening impact of the waves that are felt there.
The Mouth of Hell is a sea arch and unique cliffs near the town of Cascais made up of high cliffs, eroded by the force of the Atlantic Ocean, originally it was a sea cave that later collapsed leaving an abyss and a sea arch.
At this opening the Atlantic waves break continuously, during winter storms the fierce waves hit the arch of the sea similar to an erupting volcano, hence the dramatic name “Boca do Inferno”.
Boca do Inferno was formed by erosion of the limestone on the cliff face initially led to the excavation of a cave which slowly expanded over the generations, the stronger outer rock remained whilst the weaker rock was eroded to such an extent that the roof of the cave collapsed forming the unique Boca do Inferno.
The feature that makes up the rock in the cliff is carbonated in nature, erosion caused by the action of rainwater containing dissolved carbon dioxide causes the carbonate to dissolve, cavities and caves are formed inside the limestone.
In the past, the site was an ancient cave, and with the collapse of the upper layers of the cave it was destroyed, leaving a huge open-air cavity.
Currently, the sea, with violent and merciless clashes, rises in a white and deadly foam for tens of meters, continuing to wear down the ancient rock, increasing the spectacularity and size of Boca do Inferno.
In 1896, a film made by the Englishman Henry Short already showed the tireless force of the sea hitting the rocks at the location.
The place became well known for being the scene of Aleister Crowley's suicide and where the 1st Baron of Água-Izé rode out on horseback when he visited the Kingdom of Portugal on its island of São Tomé.
A place with steep rocks, cliffs is great for watching the sunset, taking an evening and morning walk, cycling, surfing because there are high waves.
The observation platform is a place where you can see the cliffs, the sea arch, when the waves are calm it is one of the favorite places to fish, a restaurant, small market stalls where they sell handicrafts to tourists.
