Boca do Inferno, Cascais

4.1
#1 of 16 in Parks in 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.

  • While staying in Alfama it was recommended to us to visit Boca do Inferno and the surrounding area of Cacais. So glad we did. It was a little bit of a drive, but the area is absolutely breathtaking. W...  more »
  • We visited the place a day of wind and rain, with waves of 2-3 meters. The result was impressive, with the water penetrating through the hole between the rocks and breaking into the small interior Cove.

  • This was the first place I have visited when I came to Cascais. And it was great. So beautiful and in the same time so scary, but not have fear. Amazing place for taking photos and videos. Relaxing. Beautiful view to Atlantic Ocean.
  • A simply stunning piece of the coast. I could have stayed and watched the waves crash into this marvellous cave for hours. Great vantage point that will have photographers and nature lovers gawping. If you can get out there on a windy day woth rough seas it is truly monumental.
  • This is truly a stunning place. It is unique each time, depending in the tide, the wind... On some days you can be in for a majestic demonstration of the ocean power! A must see! Amazing for sunsets too... it's about 20-30 minutes walk from the train station of Cascais.
  • Lots of fun, raw beauty and power of the sea. Worth a quick stop then shop at the great stores by the restaurant. Very good prices, better than in town or Lisbon.
  • Cool spot to chill out and grab a coffee. Fantastic scenery and some estoric connections with aleiseter Crowley. If your driving around this neck of the woods be sure not to miss this site.
