Cova de la Torre Negra

Access to the cavity once past the iron cover is via a shaft of about 3 metres; at the base there is a gallery with a length of 10 metres where one can advance upright until reaching a rock bridge. From this initial gallery the other galleries that make up the whole cave branch off, three of them on the right-hand side as we enter, and the fourth on the left-hand side, totalling 76 metres of passage.

The first gallery is found beneath the entrance mouth; the gallery has a low ceiling and forms two branches, one opposite the main gallery, while the other can be followed to the left for about three metres.

A few metres before reaching the rock bridge, we find a second gallery on the right; this one has a very low ceiling and a width of 1 to 1.5 metres, with a length of about 6 metres, ending in a small rounded chamber where one can turn around. At the far end of the entrance gallery, where we find the rock bridge, two galleries branch off in opposite directions; the right one will take us to a rounded chamber about a couple of metres high. The left one, after a low passage, the gallery regains height but only for a short time, as one must continue in a N direction along a gallery one metre wide and with a very low ceiling for four metres. The gallery continues with little height and a slight upward trend until reaching a trifurcation. In a S direction to the left we can continue for 5 metres through a narrow, slightly descending passage. From the trifurcation we can also continue in a straight line relative to our arrival; this continuation is ascending in form and begins with a narrow passage that leads us to a dome where we can stand upright. From this dome we can continue through a short stooping passage to a second chamber where this passage ends. Back at the trifurcation, we will follow in a NE direction through a wide but low chamber, seeking the easternmost end. At this point we enter a gallery where one can walk upright. Towards the E, the gallery presents a vertical step that is easy to climb and ends after a few metres; at this point we find a chimney 4 metres high. On the W side of this gallery, one must access it from its entrance, where we can overcome a short one-metre step that will allow us to cover about 5 metres, ending in a chimney 6 metres high.
