From the Casino de Burés in Castellbell i El Vilar, we will follow along Carrer Camí de Burés; after 295 metres, already outside the cluster of houses, on the left of the path there is a widening of it outside the asphalted stretch, the point where a steep, vegetation-filled gully with an abundance of brambles begins. According to the data, the small cave entrance should be at this point, but it has not been located; we very much fear that it has been covered by the earth movement when this stretch of track was widened. Approximate coordinates.
