On the N slope of the turó de la Malesa. To reach it, take a path that leaves to the left of the road from Terrassa to Castellar del Vallès, shortly before crossing the bridge over the Ripoll river. This path continues level as far as the turó de la Malesa, where it ends in a small square. From here a small path leads to the Ripoll river, in front of the well-known Gorg d'en Fitó; a little before reaching the river, the chaos of blocks produced by the fracturing of the rock can be seen on the left. At the upper end of the parallel fractures lies this fissure. Approximate coordinates of low precision.
