Follow rugged coastal paths, enjoy sweeping ocean vistas and marvel at the power of nature at this stunning natural attraction with an ominous name.

Translated as “Hell’s Mouth,” Boca do Inferno is a coastal rock formation just a short walk or bike ride west of the seaside resort of Cascais. See the rock arch and cove formed after the collapse of a coastal cave, the result of endless pounding of powerful ocean waves.

Take a walk along the 1-mile (1.5-kilometer) path that leads from the center of Cascais to Boca do Inferno. The picturesque walk takes you past the scenic Cascais Marina and the iconic Santa Marta Lighthouse. Take your time on your way to chat with the local fishermen who cast their lines from the rocky shores leading up to Boca do Inferno. A cycle path also follows this route and there is an access road for vehicles, if you want to opt for a quicker alternative to walking.

Tread carefully when you arrive at the arch because the path continues on down the cliff face. Enjoy the impressive close-up views of the clear blue water that washes in from the ocean. Notice how over millennia the softer rock was eroded by the waves to form a cave, which then partially collapsed in on itself to form the perfect arch and natural pool you see today.

Head to the lookout point for the best views of Boca do Inferno and the Atlantic Ocean and watch in awe as the waves crash against the rocks at the bottom, creating a foaming mass of white water. This powerful flushing motion inspired the name of Hell’s Mouth.

The spectacle is especially impressive to watch during rougher weather if you are willing to brave getting wet and windswept. Milder conditions in the summer still provide very enjoyable views.

Return to Boca do Inferno in the late afternoon for a chance to catch a beautiful sunset over the rocky coastline and ocean. Bring a picnic and a bottle of local wine and find your own private spot along the coast to be one with nature.

Boca do Inferno is on public land and is accessible at all times, free of charge. It is easy to reach on foot or by bike, but if you decide to come by car, there is a car park next to the on-site restaurant.
