Approach
From the Jitu Escarandi carpark head over the obvious small col and skirt round the right hand side heading for the obvious gap between two small cols. Follow the track down-hill, through a leafy area. An obvious depression contains a small pile of rocks dug from the entrance and a cheese cave door is visible low and, on the right.

Entrance
Small obvious cheese cave at side of depression Entrance

Description
The entrance passage slopes down to a chamber with evidence of cheese storage racks on the left. A high-level tube on the left has not been explored. The passage continues down through to a short drop down to a junction. Left and up leads to an awkward crawl up to a low boulder strewn chamber. Straight ahead leads to a short flat out crawl to a calcited section of passage. A low slot on the right leads to a muddy tube descending to a tight squeeze. Beyond the squeeze the passage continues but has not been explored.

Back at the junction a low crawl at floor level, with an obvious draft, is the way on deeper into the cave. The passage turns sharp right to a very tight section, The Constriction of Doom. The constriction is approx. 6m long, with the tightest bit in the middle, ending on a small debris filled chamber. Straight ahead over further debris leads to a dead end. The way on is down through an obvious hole in the floor, to The Corkscrew, best tackled feet first facing into the cave.

At the bottom a crawl arrives at the top of the first 10m pitch. The second pitch follows immediately and is another 10m to an awkward 4m climb down to a chamber.

The passage descends to the top of the third Sword Pitch.

A bolted traverse across the wall from the pitch head leads to the start of what appears to be a large older passage which immediately chokes with mud and boulders. There is a possible dig on the left hand side of the passage, but this is not considered to be a promising prospect due to the lack of draft.

The pitch is 30m, split with a rebelay approx. 5m down. At the base of Sword Pitch a 2m climb up on the right-hand side leads to the start of the fourth (6m) and fifth (5m) pitches, which can be rigged as one. At the bottom of the fifth pitch a low crawl leads back to a pitch parallel to Sword Pitch, but this has not been explored.

A winding rift passage leads to the sixth (4m) pitch into the Waiting Room, a small sandy chamber. At the bottom of the chamber a series of flat out crawls leads to a tight rift with a draught The Departure Lounge. The rift has been enlarged at the head of the seventh (7m) pitch, quickly leading to the eight (8m) and ninth (10m) pitches.

The final pitch lands in a roomy chamber which has been completely filled with breccia at some point in the past. A climb over the top of this breccia leads to a large high chamber completely chokes after around 30m. A small drafting hole calcited hole at the far end seems to drop down into the immature passage underneath the breccia. A route through breccia at the far end of the final chamber, opposite where the final pitch lands, leads to a drop down at the end of the chamber and an immature streamway. The streamway drafts but is tight. It can be forced round a right-hand and then left-hand bend to a lowering of the roof. The passage continues beyond and appears to drop slightly but attempts to push further along have failed. This is considered to be modern immature development and not likely to be worth further effort.
