Steep climb with a little scrambling. Only a very short section…….. after that it is more relaxed and less steep. Surefootedness required.

The Höllenschlund lives up to its name during storms/bad weather and lashing waves. But even in 'normal weather', this is simply a wonderfully scenic spot.

Place of interest in Cascais visited by all tourists! Generally, in spring and summer, the sea is calm and Boca do Inferno has little movement. But if you get to see it in autumn or winter after a storm, the mouth roars and has an inexplicable energy 🌊

Exciting, large, deep rock hole with a connection to the water. If you carefully look down into the chimney-like rock hole, you can see (and even hear) the surf pouring through the tunnel- or gate-like opening in the coastal rock into the hollow.
