Boca do Inferno, Cascais

 How I added Boca do Inferno to my Must See list

When I was doing my research on Sintra and Cabo da Roca, I came across a blog post that belongs to a Romanian actress. She talked about two beautiful places to visit if you’re in Lisbon: Cabo da Roca and Boca do Inferno. I hadn’t heard about the latter until that moment, so I jumped at the chance to find out more about it. The amazing background in her photos convinced me to read more about it.

When I got to Cascais, guess what was the first thing I visited?


What is Boca do Inferno?

Simply, Boca do Inferno (translated: Hell’s Mouth) is a rock formation on the edge of the ocean. It is believed that in the past, there was a cave that eroded over time. What we can see today is an open cavity where the water meets the rocks, the mouth of the collapsed cave.

Getting to Boca do Inferno

I got to Cascais by train from Lisbon station. (I wrote more about this in my post about Cascais).

After arriving in Cascais, getting to Boca do Inferno is really easy.

Boca do Inferno is 1.6 km far from Cascais Station.


You have 3 options:

  • Take bus 427. The bus station is exactly in front of the train station. The timetable for 427 buses can be found here. Mainly, there are 4 buses/hour. The trip is 1 euro and you can pay this directly to the driver. It takes around 25-30 minutes to get there.
  • Take an Uber. The Uber service works very good in Cascais. The fare is around 3-4 euros from Cascais Train Station
  • Go by foot. You can go there by foot if you have time


I chose the first option to get to the Boca do Inferno. The bus ride is pretty nice as it gets you to places that you otherwise wouldn’t get to see.


Boca do Inferno through my eyes

Boca do Inferno was a nice surprise for me. It offers a very nice, calming view – big waves that come and crash into the rocks again and again. I don’t know about you guys, but some of the best moments I’ve had during my travels somehow involved waves and a shoreline and Boca do Inferno definitely doesn’t lack in any of these two aspects.


You can consider spending from 15 to 30 minutes just to watch the waves.


When I got there the place was not very crowded, but tourists keep coming and coming.

Look around and don’t miss the fishermen who spend the day there.



From Boca do Inferno to the Cascais city centre

All of the above options can be applied backwards. I personally chose Uber because I wanted to get to the city centre fast, so I paid 3 euros to get there. The Uber arrived in no more than 3 minutes.


Around Boca do Inferno

Near Boca do Inferno you can find some shops and restaurants. The place was rather crowded, so I’d say that a lot of people come here during the day, so please keep that in mind when making arrangements (maybe you make reservations to be on the safe side, in case you do decide to grab a bite to eat here).


Is it worth going there?

The next question is obviously whether going there is worth it. I’d say that the place is nice and totally worth a shot if you have time. If you’re on a short break in Cascais, then you should probably stay in the city.
