Approach

It is located on the right bank of the Corbera River. The best way to get there is to start from the road that links La Quintana with Bejes, from the bridge that crosses the river ascend parallel to it, following the path of the river. Approx. 50 meters after the old bridge over the Corbera River is the entrance of the cave (which supplies the town with water)

Entrance

Unknown

Description

The entrance is a tube, which acts as a flood overflow. After about 8m is a small lake that supplies water to Bejes. To the right is a waterfall of about 3m to access the cave.
 
 After a hundred meters of meanders, there is a 18m waterfall that must be scaled (handline) to another meander. The passage evetually reaches a pot which is best accessed by climbing in the meander a little way back.
 
The meander narrows at the "paso del egipcio" (Walk like an Egyptian?) leading to 60m of more meander a a window on the right that leads to old fossil galleries.
 
Following the river for another 200m in the meander reaches the sump "Terminal 86"
 
The fossil galleries lead to a 2m narrow step into more  "Intermediate Galleries", the first on the left after about 70m drops back to the stream.   The one on the right ends after a few meters.
 
The second passage on the left leads for a further 50m and drops back to the original fossil level.  Continuing over the passage leads to a junction.  Following the gallery on the left and after descending a steep ramp, the streamway is rejoined,most likely the other side of Terminal 86 sump.  Only a few meters further in the steam reaches another sump. On the left of the sump is a ramp to a muddy tube, followed bya boulder choke.  A tube leads back to the ramp and the streamway.
 
From the muddy tube continuing in the direction of the river passes a boulder collapse before rejoining the river.  A sump is encounted soon after.  A hole on the right leads to 200m of passage.
 
Taking right had passage back at the junction, another junction is reached.  One route closing down quickly.  The left route leads for 50m to a large waterfall. This can be passed lowe down to 500m of passage ending in a boulder choke.  There are several inlets in the area
