There are names that spark curiosity the moment you hear them. “Mata dos Medos” is one of them: it sounds like a horror movie, but it hides a story far more peaceful and beautiful than its name suggests. Just a few minutes from Lisbon, in Charneca de Caparica, this natural sanctuary of about 340 hectares by the sea features centuries-old pine forests, trails along the edge of a fossil cliff, and views that make you forget the capital is right next door.
A name that fools everyone

No one needs to fear the Mata dos Medos—at least not for the reason the name suggests. According to the Priberam dictionary, a “medo” (or “médão”) is, in fact, a wind-formed mound of sand by the sea—a simple dune. The name doesn’t refer to ghosts or dark legends: it refers to the landscape that existed there (and still partly exists) long before the forest took shape.
The forest a king ordered to be planted to combat the dunes
The story begins with a very real problem: the dunes were encroaching on the region’s farmland, and someone had to stop them. That someone was King João V, who in the 18th century ordered pine trees to be planted precisely to stabilize the sand and prevent its eastward advance. It was this royal origin that also earned it another name, still used today: “Pinhal do Rei” (the King’s Pine Forest).
Botanical Reserve since 1971
More than two and a half centuries after it was planted, the richness of this forest’s ecosystem was officially recognized: in 1971, it was designated a Botanical Reserve, and today it is part of the Arriba Fóssil da Costa da Caparica Protected Landscape. Along about 5 kilometers of coastline, beach juniper, arbutus, and stone pine predominate, and, if you’re lucky, you might spot booted eagles or tawny owls soaring above the treetops. At the western edge of the forest, where the trails end at the cliff’s edge, you’ll be rewarded with a view of the Atlantic framed by Cabo Espichel and the Sintra Mountains. For those who want to go beyond the trail, the Mata dos Medos Interpretation Center organizes guided tours, exhibitions, and environmental education workshops.
Hiking along the forest trails

From the picnic area, next to the Interpretation Center,two hiking trailsbranch out through the pine trees, alternating between stretches of loose sand and wooden walkways. Along the way, the air is filled with the scents of sage, rosemary, and thyme—typical of the Mediterranean vegetation that covers the forest. One of the most popular trails, theMata dos Medos Flora and Vegetation Trail, is an easy-to-moderate loop of about5 km, with a total elevation gain of just 92 meters and an average duration of1 to 1.5 hours, requiring no special physical conditioning. Throughout the year, the Interpretation Center and other local organizations also host themed hikes and nature-based activities open to the public, which are usually announced in advance.
A forest that also became a book
Mata dos Medos has inspired not only weekend hikers but also a writer. Álvaro Magalhães set “Contos da Mata dos Medos” in this forest—a children’s book recommended by the National Reading Plan for 4th graders—featuring talking animals—a hedgehog, a mole, a titmouse, a snail, and a caterpillar—that inhabit this very landscape between Almada and Sesimbra.
How to get there from Lisbon
Mata dos Medos is about 20 to 30 minutes from Lisbon, on the other side of the 25 de Abril Bridge, in the parish of Charneca de Caparica, municipality of Almada—close enough for a quick getaway of a few hours, yet far enough away to feel like another world.
