An entrance 7 by 2.5 metres through which one enters a straight gallery 38 metres long that gradually decreases in section until a narrow passage, later cleared, which two metres further on meets a gallery that cuts the main one perpendicularly. Continuing to the right, past some gours, a twist and crawling through a small gallery, almost filled up with clay, one reaches the final part of the large Cova Simanya, although the passage is obstructed by a stalagmitic crust that is difficult to clear and that allows no more than holding hands from one cave to the other.

Returning to the crossing and continuing to the left through a narrow and long passage, with a small change of direction that makes the passage of the feet difficult, one reaches a gallery of regular forms that gradually increases in height only to decrease again until it is filled up by sediments. But to the right there is a narrow passage that leads us to a level of (it seems) the same gallery, which within a few metres is cut almost perpendicularly by another of equal or similar orientation to the main one and 2.5 metres further on changes orientation again.

From here almost to the end, the floor is made up of sand and small pebbles. Finally, after 4 metres the gallery will change direction again to take the same one as the main entrance gallery and after a narrow stretch, the gallery becomes high and wide for some 14 metres, where the conduit becomes low and ends filled up with sediments, blocks and clay.

The passage that communicates with the large Cova Simanya is obstructed by a stalagmitic crust that is difficult to clear.

An ancient spring of the same Cova Simanya system and in an advanced state of fossilization.
