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.

Boca do Inferno Reviews
Wonderful view on a sunny day. It would be a must to walk along this part of the waterfront and get to know the cliffs and stone beaches to the Boca do Inferno (main one). more »
Great rock's formations, caves with waves splashing. Great place to visit close to sunset. Visiting at high tide, if possible, would give some amazing experience. more »
It was just quick stop for us as we were having a road trip heading to the north. Impressive to see the waves and water crashing through this interestingly shaped cliff. We only spent there about 10 minutes though as the weather was very windy and chilly since we did our trip in December.
Amazing view, one nit to be missed... and not that far from the main downtown area, we did a walking tour there. No real hilly area you have to strain with as is much of Lisbon. Spectacular view, and when arriving there was entertainment man playing the guitar, restrooms available and food options so you can take a breather from your travels. Recommend!
