A short resurgence cave which ends at a sump. The passage swings to the left at the dam, not right as shown on the old survey. A dye test in 1964 showed water from Sima-Cueva del Risco (025) resurging after five hours from this cave, Cueva de Transformador (032) and in Cueva de Tiva (026).

A visit in 1995 showed that the site was probably shallow and passable with a small amount of diving gear. In the summer 2013, the repaired dam was keeping water higher than before. In April 2016, it was called an "easy looking dive". The site was re-surveyed in 2019.

La Lisa (site 3929) is the spring below.
