Avenc de la Vinya d'en Tomàs

The entrance is funnel-shaped and leads to a small shaft 3 metres deep. In an E direction there is a small hole and by means of a 2.5 metre drop one reaches a room running SE. On the E side of this room there is a small hole that leads to a gallery 7 metres long. This gallery is the continuation of the room, but due to a mechanoclastic process it is obstructed by a large block. Towards the end, the gallery turns in an S direction and further on in an SE direction, a very narrow point where the cavity ends. Returning, in the room at the beginning, at mid-height there is another gallery 8 metres long, 3 metres high and less than one metre wide. At the end, on the left side and after overcoming a small drop, there is another gallery of 4 metres following the same direction as the previous one.

The cavity opens in one of the terraces artificially stepped with stone walls to support them and use them for cultivation, hence its name Vinya d'en Tomàs; they are currently abandoned and wild vegetation covers everything.
