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 🌊

Praia do Abano is a charming little cove located north of the famous Praia do Guincho, within the Sintra-Cascais Natural Park, in the municipality of Cascais. It's an ideal spot for those seeking a quieter, wilder, and more natural beach experience.

A good place for walking and cycling. One detail: the horses in the photo are not wild. They belong to the Sorraia breed - https://pt.wikipedia.org/wiki/Sorraia
