- md1mmSheffield, United Kingdom1,630 contributionsDramatic wavesThis is very close to the centre of Cascais and if you are in the area you must visit. I visited in November in a relatively calm day but the experience was excellent. The whole area consists of high cliffs with the large waves breaking against them - Great for photographs. To top it all however you have to visit Boca do Inferno which is a cliff arch where the waves break through creating conditions like a huge washing machine. Sometimes the best things in life are free and this is among the best that nature throws at you. I loved it.Visited November 2023Traveled soloWritten November 6, 2023
- James SToronto, Canada1,876 contributionsSpectacular more than HellishAfter leaving Sintra our tour headed west reaching Portugal’s Atlantic coastline before following it south towards the estuary of the Tagus River. Just before the river reaches the ocean, we came across a natural wonder that has become a local attraction, the Boca Do Inferno or Hell Mouth. Along this part of the coast there are either long beaches or massive cliffs that the waves crash against. At this point they have over the centuries carved out a deep chasm which the water enters and recedes from in an invigorating show. Several viewing platforms and walkways allow one to get fairly close to the chasm in relative safety. As we were on a bus tour, we only made a brief stop here, but it was sufficient to thoroughly enjoy this natural wonder. As an added bonus we arrived at sunset and the always spectacular sunsets in this area made a great backdrop. The Boca Do Inferno is easy to reach from Lisbon along the costal highway that runs west along the north bank of the Tagus Estuary towards the costal resort towns of Estoril and Cascais. There is ample free parking on the site, as well as restrooms and a small souvenir shop and snack bar.Visited November 2023Traveled as a coupleWritten January 24, 2024
- coh8Glasgow, United Kingdom944 contributionsTake your camera and have an ice cream after your stroll30 minute walk from train station hugging the beach takes you to this impressive rock formation. Haven for photographers - loved the plaque that paid tribute to Aleister Crowley too. Very craggy and steep staircase down to main view point. While I agree with views on stalls, we just needed an ice-cream and a cold drink before heading back into town. Worth a visit.Visited July 2024Traveled with familyWritten August 16, 2024

We had already been to other beaches in Portugal and so even though the water hitting the rocks was pretty, you can see the same thing at any other beach in Portugal and not have the same crowds. I would love to be there on a stormy day.Visited September 2024Traveled with friendsWritten September 23, 2024

Located about 1km from Cascais, it's an easy walk (there's a flat path that hugs the coastline all the way from the marina). Leading up to the Boca do Inferno, there are a series of cliff faces and rock formations being battered by waves, which give you a taste of what's to come.
The Boca do Inferno itself is one of those curious naturally formed rock formations that couldn't have been hand-sculpted any better. It's effectively a lagoon with almost vertical rock faces surrounding it, save for an archway (the boca/mouth) at one end. This acts as a funnel for huge waves to come crashing into the lagoon, which creates a swirl of white water. We were mesmerised for 15 minutes, waiting for the next big wave to come crashing in, while marvelling at the birds that would swoop through the archway and perch just out of reach from the incoming waves.
If you wanted to sum up the power of the ocean in one place, the Boca is a pretty good candidate.

It’s a dramatic section o coastline. 🌊The panorama it’s dramatically but at the same time it’s fantastically.
The cliffs are so beautiful because they plunge directly in the Ocean. From up top you can see the weaves coming in hard and continuously hitting the cliffs. Such phenomenon creates an unending sound reverberating all the way up to the edge of the cliff.
There are also cafes at the Boca where you can get a snack and have a sit outside.
It’s a must see !!!

Boca do Inferno (the Mouth of Hell) is a mesmerizing place! This maritime attraction is located along the coast on the western edge of Cascais. Although still a fishing community, much of Cascais’ village charm has been replaced by hotels, restaurants, cafes, and fashionable shops. In the summer, the city is overcome with tourists from all over the world who are attracted to the weather, the beaches, the natural attractions, and the vibe.
The Mouth of Hell is what remains of an ancient cave that protrudes out towards the raw Atlantic Ocean in the form of an arch. When the ocean is calm, the strong waves move lazily through. But when the ocean is angry (or even just a little agitated), the tidal waves become oversized and crash up, into and through this space. You wouldn’t survive if you got caught up in it.
From the Cascais Marina, it is a mostly flat, easy walk which may take about 20-30 minutes. Along the walk there are spectacular ocean views. Hotels and homes line the opposite side of the road. There are also bicycle and pedestrian paths along this route. It’s also easily reachable by car with parking available at the site. You’ll also find a variety of small shops selling souvenirs, food, and gift items (most take cash only) as well as a couple of restaurants. There are public restrooms (marked WC) next to the parking lot.

This is a very interesting geological formation and well worth a visit. Parking is ample, and after a short walk you will be treated to raging wave action moving through a small channel into a large open chasm. I enjoy seeing it every time I visit Portugal, and it is a great place to take visiting friends.

What a shocking sight when you first lay my eyes on this sea cave. My imagination took me to a inferno world. As the waves crashing into the cave, sun shaken broke through the clouds form a shimmering surface

Boca do Inferno is a sea cave not far from the city of Cascais. It is named after the loud noise caused by the waves rushing into the cave during high tide. The scenery along the coastline in this area is beautiful, and there are many nearby There are many strange-shaped black boulders and cliffs, which are perfect for overlooking the Atlantic Ocean or watching the sunset. It is one of the famous local attractions.

This is an amazing formation and must be wonderful when the tide is high and the winds strong. Unfortunately when we visited all we saw were waves coming into to cove. Still an interesting spot with a good view of the cliffs rising out of the sea.

Actually, it's the cliffs nearby that I'm reviewing, the site itself is very cordoned off. This is a spectacular area, and well worth visiting. Very close by, there are amazing rocks to sit on and have a picnic. But, please, do not stand or sit on wet rocks. It may look peaceful enough work the odd high spray, but every 20 minutes or so there is a sudden almighty wave that is well and truly enough to wash someone away. The reason why the area is so-named.
I spent a couple of hours enjoying a picnic there before it got too stressful to watch...!

Got dropped off here by an Uber. Nice spot for pictures by the ocean. There are cafes, shops and restaurants around. The restaurant Mar do Inferno was highly recommended but we weren’t hungry enough. We opted to grab gelados at one of the cafes and walked down the coast towards downtown Cascais. Its a nice walk on a nice day.
