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.

  • 5 minutes is all you need and it's free and so beautiful. Exceptional place to 20 meters from the road to the sea

  • 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.

  • I would say a must do visit if you are in Cascais. We walked from our berth in the marina one evening to see the sunset which is what many others seemed to be doing! We were not disappointed in mid November. You had to pinch yourself at the fabulous weather. There are a few bars, cafes and restaurants there also if you want to make an evening of it all with the stunning views over the ocean.
  • We visited this place in December, we went from Lisbon to Cascais by train (40 minutes) and than we walked until Boca do Inferno. There is a restaurant and a little bar, where you can eat and drink and also buy local biscuits. We were lucky with the weather, lot of sunshine, so we could sit outside with our drinks. There were only few tourists, so we enjoyed the nature a lot. It must be very crowded during summer. You can also go by bike along the whole coast.
  • A must visit place ... I would recommend to walk from Cascais to Baco do inferno It’s very pleasant walk (20 - 25 min approx) and you will get to see many beautiful points (not popular point as such though) in between Best place to be there at this place around 1-2 hours before sunset ... so that you may first enjoy the wonderful view of rock cliff and admire power of sea... and then later sit down relax and watch the beautiful sunset Preferably go on a sunny day
  • Boca do Inferno (Portuguese for Hell's Mouth) is a chasm located in the seaside cliffs close to the Portuguese city of Cascais, in the District of Lisbon. The seawater has access to the deep bottom of the chasm and vigorously strikes its rocky walls, making it a popular tourist attraction. The cave was the first to be depicted in moving pictures, in the 1896 British film A Sea Cave Near Lisbon, which shows waves breaking at the mouth of the cave.
  • Very nice viewpoint, can be a bit crowded at times though. There are a few restaurants so no need to worry if your thirsty or hungry. Lots to explore on the rocks!!
