The entrance is about 40m beyond the Church Entrance to Cueva Hoyuca (107). A slope down over dry boulders leads to small passage which closes in after a rock flake. This description needs checking by Grov or Nigel D.
The cave was visited at Easter and October 2015 as a possible new entrance through Tilers' Way into Hoyuca. The muddy conditions at both ends suggests a probable link. In October, a small wet section with a mud floor and pendant, which would need a wet suit to pass, was reached. It looks similar to a corner previously seen in Tilers' Way. The original survey (from 1993, but not drawn up) ended at a sump. A resurvey was started in October 2015.
