The importance of this hole in the rock is gradually being discovered. From the large doorway in the distance, there are two holes.
One of them is totally blocked, in the other one we can play for a while with a caving experience for beginners. We see that there is also a lot of sediment filling this hole, much larger inside than its entrance would suggest.
Through one of the sides we can access a completely empty stratum in its interior. There are what appear to be cave paintings and many remains of mining activity.
