The entrance lies up in the trees on left of the northern track to Carcavueso. An excavated hole that is a crawl enlarging slightly to another excavated section up to the top of a rope climb down a 6m slippery slope into a chamber. This has some well decorated sections and leads to a climb up and down through boulders to a flat out glutinous crawl into another decorated chamber that terminates in a draughting boulder choke.
The cave trends north and lies between the eastern end of Bollón and the western end of Carcavueso.
In 2010 the entrance had collapsed.
