A wild spot by the sea
Boca do Inferno is a natural rock formation near Cascais on the Atlantic coast. It is a cliff with a large opening, formed by the sea over many years. When the waves are strong, they crash into the rocks and shoot up through the opening, making a loud sound.
The name means “Mouth of Hell.” People gave it this name because the waves can be very powerful and noisy, and the dark opening in the rocks looks a bit like a mouth. The sound of the water and the force of the waves can feel intense, especially on windy days.
Today, it is a popular place for visitors. Many people come to enjoy the view, take photos, and watch the waves.












I was there in 1968 on a holiday visit with my parents.
