Once at the Prat Llong, reached by a track from the Arp refuge, we find a track rutted by the wheels of all-terrain vehicles that crosses the Prat Llong; on the right we find a broad esplanade before the forest invades the slope. Skirting the meadow we will notice at its edge a wooden and wire fence that protects hikers from the fright of coming upon the mouth of the pit. Approximate coordinates.
