The funnel-shaped mouth allows us to descend a 6-metre shaft, preceded by a short gallery in an E direction. We will pass a very crouched squeeze that will lead us to a room 4 metres high. We will then continue along a gallery 1 metre high for about 10 metres, until, as it descends a little, we find a sump.

It is an intermittent spring that collects the waters of the Serrat del Pou, established in a N35E-S35O joint. Below the mouth, in the direction of the nearby track, one can observe a channel very hidden by vegetation, a product of the force of the water when the spring becomes active.

At present the exploration is somewhat complicated because some “foresighted” person installed at the bottom of the entrance funnel a metal mesh with iron rods and onto which debris from outside has fallen, which hinders and makes dangerous the passage inside.
