The draughting entrance is under a rock outcrop on the southern side of a field. The entrance is a "breath out" bedding plane followed by a slightly larger low crawl for about 50m to a junction with a stream. Upstream leads to a 5m duck and 30m further on a passable boulder choke and finally, a very tight, draughting hole in another choke. Downstream, after some 30m, a junction to a higher level is met. The lower level follows silty passage to a sump and draughting choke.
This is very near to the upstream sump in Cueva de Jivero 1 (016) and the connection was made at Easter 2000. The higher level splits: the southern branch ends after 40m at a draughting boulder choke; the northern route ends at two chokes with no draught.
