Botet d'Esplugafreda

A few metres from its start the entrance gallery bifurcates; on the left an upward step is climbed and it continues along a short upper gallery that ends closed at +6 metres from the entrance. Along the other gallery, on the right, it descends slightly and soon reaches a point where it is completely flooded. This first sump is 12 metres long, emerging into an air-filled gallery of narrow dimensions with an active water course; at this point a 3-metre-high step must be climbed and then descended again on the other side, where it gives access to the second sump. This one has larger dimensions; the gallery descends on a slope down to -6 metres, where the gallery continues horizontally for some metres before rising again to reach a point where there is an ascending tube that could be a bubble. The gallery descends again and ends in a passage that is currently impenetrable. The vertical range is 12 metres (+6/-6).

The flooded passage is not always flooded; in some dry periods it is possible to pass through. The first sump is 12 metres long and emerges into an air-filled gallery with an active water course. The second sump has larger dimensions and the gallery descends on a slope down to -6 metres.

On 10-06-2017 David Martinez (Proteus) passed the first sump and, after an air-filled zone with an active water course, reached a step of about 3 metres that gives access to a second sump (S2), a sump of larger dimensions where he covered 20 metres with a maximum depth of -6 metres, where an impenetrable passage blocked his way. A second dive was made by Josep Guarro, who installed a fixed line to work in the final stretch; the cave is still being explored.
