Cova d'en Genís

Cova d'en Genís (also known as Cau d'en Genís) is a natural rock formation in the municipality of Santa Coloma de Gramenet, in the Barcelonès district, recognized as a cultural asset of local interest. The site sits within Serralada de Marina park, on the southwest slope of Pollo hill, near the Sant Climent hermitage and about 500 meters from the Puig Castellar archaeological site.

What will you see?

The formation consists of a large granite boulder resting on smaller stones, creating a natural cavity resembling a burial chamber. For years the site was mistakenly classified as a megalithic construction — today it's known to be a natural rock structure, shaped by geological processes rather than human hands. The name comes from Genís Ibáñez, who discovered the site in 1955; subsequent excavations were carried out by the Centre Excursionista Puig Castellar.

Archaeological research uncovered bone remains and two ceramic vessels in the cave — one from the Neolithic tradition, the other featuring a characteristic "button" handle typical of the middle Bronze Age (1500–1100 BCE). These finds indicate the site was used by people across multiple periods, despite the natural origin of the formation itself.

How to get there?

Cova d'en Genís lies within Serralada de Marina park, reachable via hiking trails from Santa Coloma de Gramenet and surrounding towns. The route crosses Pollo hill, near the Sant Climent hermitage — a popular starting point for local hikers.

When to visit?

Serralada de Marina park is best explored in spring and autumn, when temperatures favor hiking and views over the surrounding area are clearest. In summer, it's worth setting out early in the morning due to the heat typical of the Barcelona region.
