Cave with curious erosion forms in Torrelles de Llobregat, with a 12-metre-wide rock shelter and passages of 9 and 5 metres.

Characteristics

Location

Torrelles de Llobregat: we will position ourselves at the Raval Mas; here we must follow carrer del Raval; at the end of this it becomes a track that heads towards Can Mas, currently a holiday camp house. We must follow the track until reaching the col of the serra de Can Valent, the boundary with the municipality of Cervelló; we will have covered 1,650 metres. The col forms a flat area where we can leave the vehicle; on the left-hand side, heading West, a path sets off which, in about 350 metres or so of gentle walking, brings us to a crossroads where, by the left, in a few metres it would take us to cave no. 1 of Can Mas. From this crossroads the path climbs the slope until reaching a new crossroads; we must follow the one on the right, which will take us to cave no. 4 after climbing a height difference of about 20 metres. Some time ago at this point there was a metal ladder of about 3 metres that allowed one to climb to caves no. 2 and 3, which are located just above.

Description

Morphology

A rock shelter 12 metres wide; in its easternmost and highest part a narrow ascending passage of 9 metres in length opens up. In the lower part we also find a small passage of 5 metres in length.

Other details

Its genesis is basically the product of wind erosion on the red sandstones of the buntsandstein (Triassic) and conglomerates of the buntsandstein (Triassic), entirely similar to that of the neighbouring balmes de Bruguers (Gavà). It presents the peculiar alveolar forms of this type of “taffoni”.

History

N. Font i Sagué, on page 148 of his Catàlech (1897) quotes verbatim:

Torrelles de Llobregat. 144) Coves de Can Mas.- Són varies y estan situades en la montanya qu'ils dóna nom.

Later this citation is picked up by Faura i Sans (1909) and even later by Llopis Lladó in the first editions of the Ordal maps of Editorial Alpina. Despite this, no data are given for these cavities.

It is not until April 2018 that a fellow hiker tells us about some spectacular caves in Torrelles de Llobregat. A simple internet search on different blogs and hiking routes (wikiloc) gives us news and images of some caves excavated in the Triassic sandstones and located above Can Mas. The great majority of these references call them Coves de Can Riera (taking as a reference the house located not far away, but in the municipality of Cervelló). Others also call them Cova Vermella and Cova Bonica.

There is no doubt that these curious cavities, very well known for a long time by hikers, are none other than those cited by Font i Sagué more than 120 years ago.
