      Translated, "Boca Do Inferno" means Hell's Mouth. It not only sounds exciting, it is!

      The cliff lives up to its name and is one of the top tips for Cascais attractions.

      Hell's Mouth is a large rock arch on the cliffs on the western edge of Cascais. The sea flows both in and out here, letting the waves crash against the cliffs with their own force. The water can sometimes splash a few meters high - hence the dramatic name...

      You can also spend a romantic evening at sunset 💙...
