Portuguese for ‘Hell’s Mouth’, Boca do Inferno is a rift formation at one of the seaside cliffs in Cascais. The intense and mysterious name of the chasm and its natural beauty make it a popular tourist attraction.

The chasm seen on the cliff of ‘Hell’s Mouth’ is the result of strong water waves crashing onto the cliff surface rapidly and repeatedly. This caused the surface to collapse, giving it a mouth like natural arch. During summer the waters merely make a soothing splash. But in winters, the full force of the Atlantic waves comes crashing onto the cave and is quite a dramatic sight.

Legend has it that an evil sorcerer lived in a castle on these cliffs. He abducted a beautiful woman and held her captive in the castle. She was discovered by a man who fell in love with her and helped her escape. The jilted sorcerer unleashed a dreadful storm to destroy the rocks where the women and her beau walked thus causing the large gaping hole.

  • Tourists can take a closer look at Boca do Inferno by climbing down the cliff from one of many designated pathways.
  • Boca do Inferno is also one of the best places to purchase souvenir items. There are stalls close to the cliff site which offer a good deal on many lovely little items. 

The area has many cafés and restaurant. But if you are not in the mood to sit and dine, you can purchase a nice little snack from the wandering vendors.

  • 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.

  • 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!!

  • 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.[1] 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.[2][3]

  • Great place to see the waves smashing against the cliffs. However, if the ocean is calm, it's not more impressive than other places in the area.

  • Must do in Carcais region. Friendly local who was fishing. Watched him fish for an hour.
