A through trip. Climb up into bottom entrance immediately enters a superb phreatic tunnel containing the stream. A sandy gallery on the right soon closes down. The streamway continues to emerge at the twin openings of the upper entrance.

The following fauna is listed by Notenboom (AX): Echinogammarus/Gammarus, Cyclopoidea, Prosobranchia/Hydrobioidea,Proasellus ocul., Ostracoda, Pulmonata/Basommatophora, Bivalvia/ Sphaeriidae, Insecta, Oligochaeta and Nematoda.

Also Ortiz (AM) records the following crustaceans: Asellus coxalis ssp. and Gammarus berilloni Catta. The cray fish were particularly abundant during 1999 and 2000 and care should be taken when passing pools of water.

At Easter 1996, it was recognised that, along with the remains of an old mill in the depression between Cuevas de Jivero 2 and 3, slots in the wall of the downstream entrance to Jivero 2 indicated the use of a possible wooden-boarded dam and / or an overshoot mill wheel. There is also a wall built about 15m inside the top entrance.
