Approach

Heading from Arenas de Cabrales toward Poncebos. The signposted 'Cheese Cave' is passed. On the right(?) hand side of the Cares river (as you drive up the mountain): 1st Resurgence = Fuente de la Lisa 2nd Resurgence = Fuente de Obar

Entrance

Resurgence

Description

the cave stretches over 670m and includes four sumps.   Sump 1 is 83m (-8m depth) from the entrance.  The passage then rises to a point +61m, to a 32m long chamber, with flat and sandy soil, and the "Domino" pitch on the right leads to sump 2
 
The main passage continues to sumps 3 (25m depth -3m) and sump 4 (cave height +30m)
 
the active cave is largely impenetrable. the water comes from sump 4 which has not been explored (1985).  The passage between Sump 3 and Sump4 is very narrow and covered in white calcite.
 
Sump 2 has not been explored but probably leads to a large unexplored (but submeged section)
 
This resurgence has an inlet within Sump 1 that contains warm incoming water (23 degrees C).
 

Reference

Spelunca 19, supp. (1985)

Notes

The S.S.S Geneve plunges the siphon of entry in 1978 and stops, on the one hand, on an impenetrable siphon and, on the other hand, on the point of climbing. in the years 1979 to 1980, explorations continue and two others are plunged
