   The relative positions of the 3 sites to the southeast can be seen here.
   A small entrance lies about 15m to the northwest of an obvious goat shelter (site 2682) at the head of a small wooded valley, above Cueva del Haya (0178). The hole drops onto a slope down into a chamber. Some mixed pottery pieces have been found on the left of the slope which are classed as Bronze Age, Romano-indigenous and medieval. These pieces are discussed in Ruiz Cobo Jesús and Smith Peter et al, 2001 and mentioned in Ruiz Cobo Jesús et al, 2008, p209. On the right, parallel passages soon choke. In 2007, beyond the pools down to the right, a ramp "leading up above the low bit" was noted. Has this been explored?
   A second entrance (5208) lies just to the northwest of the goat pen, in the cliff.
   Some re-exploration in the summer 2022 ended after encountering "masses of slippery mud with only one rope and ladder".

Description (updated summer 2015, Peter Smith)
   At the end of the entrance chamber a squeeze enters a well decorated room with a nice gour floor. A climb of 4m up flowstone leads to a large chamber with a loose slope to the head of a shaft. By scrambling around the top, a large passage is reached. To the north east, a well decorated tunnel passes a blind 10m pitch and ends after 120m very close to the surface. To the southwest, a decorated passage becomes smaller until a squeeze onto the head of a greasy, sloping 50m pitch that connects with the shaft in the chamber. This is broken by ledges and ends on boulders which slope down to a dismal sump at valley level.
