Boca do Inferno, Cascais

4.2
#1 of 7 in Nature in Lisbon District
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.

  • A super easy pit stop if you're already in Cascais. A good viewpoint of the cliffs in the area and the ocean. Great views and you may be able to even spot a few local fishermen in the area. Be careful with getting to close to any edge and respect the safety signs; this place is not named after a particularly tame weather/waves. If you're lucky though you may be able to - safely - experience the power and magnificence of the Atlantic ocean as its waves crash into the cliffs. There's even a restaurant glued to it and while you probably would assume it's a touristic trap due its proximity to a landmark, the restaurant actually caters to a large local crowd and is a really nice place to get some really fresh seafood (although I would have to argue the prices are much more touristy than I remember them in my youth - this just for the restaurant; Boca do Inferno is completely for free).
  • Interesting spot to visit. Not too large in size. It's a very rocky area with warning signs near the cliff edge. Nice to watch and listen to the waves caressing the rock, and swishing back out to sea. There is a small market selling cork bags, embroidered tablecloths, household items and souvenirs. Couple of nice coffee shops to sit outside and watch the world go by!
