Boca do Inferno, Cascais
Boca do Inferno, or "The Mouth of Hell," features a natural rock arch with a cave that is known for sucking in ocean waves and shooting water out the top. Nestled in a dramatic environment of eroded cliffs and enormous waves, the site is a well-known photography spot. You can easily reach it by foot, and then follow stairs and bridges around it to get a better view or climb down to the cave if the ocean is calm. Be aware, however, that locals advise against climbing due to the sharp rocks.

De part la proximité avec Cascais il y a beaucoup de monde, surtout l'après midi. Cela mérite un arrêt si vous avez le temps. more »From the proximity to Cascais there are many people, especially in the afternoon. This deserves a stop if you have time.
Hyggelig gå tur op dertil, hvor der var en fantastisk udsigt. Vi tog en cykel taxi ned igen, det kan anbefaledes more »Nice walking trip up there where there was a great view. We took a bike taxi down again, it could be recommended
Wonderful place to be.. would say nothing much to see but still enjoyable to see nature at work and how waves keep hitting the rocky sides. Treat to see waves and hear the sound of ocean. There is small market near the spot where shopping can be done for bags, etc.. prices out here were quite economic compared to other places, only catch is that you will need cash as none of those shops accept card.
Awesome place to visit in Cascais If you want to connect to nature. It is a rocky cliff by the ocean with a water passage under it so you can see water on the outside and also inside. It's so stunning and magnificent that it's hard to describe. You must visit this place and feel it's energy by yourself.
