Ascending fissure on the Sant Jeroni wall (Montserrat), in the municipality of Marganell.

We will leave the car at the old lower station of the Sant Jeroni cable car, we go up the asphalt ramp that starts beside the road to head for the uphill stretch that in a few minutes brings us to the camí de l'Arrel.

We take the direction of the cable car wall to reach a small bend where we will begin to climb up the torrent de l'escletxa del Moro; the start is very obvious, a boulder-strewn gully that we will have to scramble up, until we find some more complicated sections with fixed ropes, which we will follow, to which a via ferrata cable is then added. This is the route used by climbers for the approach to most of the routes on the cable car wall.

Once past the ropes, we will have to follow the base of the wall to the left in an ascending direction. We will reach a more vertical zone, having to overcome a step by scrambling up a few rather complicated metres. Suddenly we enter a large and spectacular cave.
