Have you ever been to Hell's Mouth?

The Boca do Inferno is an interesting cliff formation close to Cascais, which has been given an overly dramatic name of Hell's Mouth. The ceaseless pounding of the Atlantic Ocean on the cliffs chiselled out a small cave, which subsequently collapsed forming a small bay and natural arch.

What People Are Saying

★★★★★
"It was really a great experience to visit Sintra and Cabo da Roca. We enjoyed visting Cascais as well, although not as much as Sintra and Cabo. Our guide, Diego, was very knowledgable and we learned a lot from him about both sites, and their historical background. We particularly want to praise Diego for being a brilliant driver, making us feel relaxed and safe during the whole tour. We would certainly recommend this tour with Experitour."
