Cova Gran de les Fogueroses

Cova Gran de les Fogueroses is a cave near Sant Llorenç Savall, in Catalonia, tucked into the rock formations of the Sant Llorenç del Munt massif at roughly 910 meters above sea level. It sits within the Sant Llorenç del Munt i la Serra de l'Obac natural park, in an area known as Les Fogueroses — a cluster of cliffs and rocky outcrops in the Vallès Occidental district. It remains a niche destination compared to the park's better-known trails, drawing mostly hikers and caving enthusiasts rather than casual sightseers.

How do you get there?

Access follows the marked trails of Sant Llorenç del Munt park, typically starting from the mountain refuge or one of the trailheads around Sant Llorenç Savall. The final stretch involves a steep rocky ramp near a formation known as El Paller, which makes the approach demanding for less experienced walkers. Sturdy hiking boots and a headlamp are worth carrying — the surrounding limestone terrain is rugged, and the paths leading to the cave are not signposted as clearly as the park's main routes.

What will you find inside?

The cave stretches roughly 120 meters through a series of galleries on different levels. Its most distinctive feature is the entrance itself: barely half a meter wide but more than four meters tall, creating an unusually narrow, vertical passage before the cave opens up. Inside, visitors find one of the richer stalactite displays in the area, though some formations show damage from natural weathering and past visitors. The multi-level layout means careful footing is essential, particularly through the tighter sections.

A bit of history

The only known survey of the cave dates back to 1975, produced by three members of the Speleo Club de Sabadell: J. Anglarill, Ll. Canet, and J. Renom. Their measurements remain the reference point for understanding the cave's layout and dimensions. Cova Gran de les Fogueroses is known locally among cavers and hikers exploring the Sant Llorenç del Munt massif, but it isn't among the most visited underground sites in Catalonia.

When should you visit?

Spring and autumn are the best seasons, when temperatures across the park stay moderate and the approach trail isn't baking under summer sun. Summer heat can make the rocky climb uncomfortable, while winter rain or frost can leave the final ramp slippery. Whatever the season, it's worth checking recent weather and avoiding a visit right after heavy rain, when the rock surfaces turn wet and unstable.

Frequently asked questions

Do you need special equipment to visit the cave? For the accessible part, a headlamp, solid hiking boots, and caution at the narrow entrance are enough. Exploring the deeper galleries, however, calls for caving experience or a guide familiar with the terrain.

Is the cave suitable for children? Given the narrow, tall entrance and the steep rocky approach, it suits older children and adults with reasonable fitness rather than young kids.

How long does the hike from Sant Llorenç Savall take? It depends on the trailhead you choose within the park, but the final approach with the rocky ramp is a short, if demanding, stretch of the route.

Is the cave lit or marked with signs inside? No — Cova Gran de les Fogueroses is a natural, unlit cave with no tourist infrastructure, consistent with the wilder character of the Sant Llorenç del Munt i la Serra de l'Obac natural park.
