Driving along the road that links Vallirana and Olesa de Bonesvalls past the housing developments, when these end and after the Avenc de la Cuneta you must take the last street on the right (Carrer del Serral Llarg) and climb almost to the upper area. Before a sharp right-hand bend, the street Carrer de Taubadella comes out on the left, which you must follow to the end into a small round square. From here we continue on foot along a faint path, without losing height, until we reach a sparse ridge where we change slope and a few scattered cairns help us find the Escletxa dels Bancarrassos. A few metres above it lies the pit or hole of the same name.
