Translation:
Name: Cubilla (also called Penilla in some OUCC documents)
Location: Near Castro Urdiales
GPS: N43°21'41" W3°16'37"
UTM: 30T 477.67 4801.20
Lambert: 6334 9732
Map: tbd
Survey: OUCC 1967 » (known to be missing side passages near the entrance)
Description: Large cave (1000m) explored in 1966/67 by OUCC;
See OUCC Report 1967 » (called ‘Penilla’ in that report).
Easy parking off the ‘main’ road is at N43°21'45" W3°16'34"; there’s a good, if steep, track down from there beside/behind
the noticeboard.
Visits:
2000 – brief initial exploration
2001 – explore major inlet series on the right (with Spanish survey mark F7); this is missing from the survey and yet sources all the water in the cave – meaning that the main stream is completely unaccounted for
2003 – GPS
2007 – brief ‘warm-up’ trip
2018 – drone flights and short visit
Other:
Worth another visit.
