Avenc de Sant Antoni

An excavation of 6 metres of passage in the form of a trench, on the slope of the hill, brings us to an old metal door 1.70 metres high and 0.80 metres wide. Once through it we find an artificially excavated tunnel (1.50 x 1 m.) 2.50 metres long that leads us to a chamber, already in the natural cave, which shows clear signs of having been excavated and its sediments removed, in order to level the ground, leaving in the centre some "islets" of the old sediments that are 1.70 metres high.

If we advance to the right we will find a ledge at + 2.40 metres high, where there is an abandoned nest, and behind it continues a narrow crawlway, not accessible.

Continuing to inspect the chamber along the right wall, we will reach a gallery of about 10 metres, at the end a crawlway leads us to another small gallery 3 metres long, 0.50 wide and 1.80 high that ends with a turn to the left and a step that continues with a one-metre micro-crawlway.

Returning to the entrance of the crawlway, on our left there is a flat-out passage that allows us to enter a few metres and which, although we cannot progress due to the narrowness, we do know acoustically that it communicates with another point that we will discuss later.

Turning back we will see the light from outside and we will approach another chamber where, on the ceiling, we see the mouth of the pit. In the past this must have been the only entrance to the cave.

It is a mouth 0.84 x 0.75 metres with the remains of an old trapdoor that covered the access. This shaft is 3.40 metres deep. The chamber has a cone of debris from outside, and, in a W direction, a small descending gallery of about 7 metres of passage becomes narrower until it turns into an impenetrable crawlway. On the right, another crawlway is the one that communicates acoustically with the one described above.

If we return to the entrance, and go to the left, after the "islets" we will find a climb and we will soon reach the small chamber of the aforementioned shaft.
