There is a well-established path to the bivouac site at the eponymous stone bridge, which is the usual base for CUCC's operations on the Schwarzmooskogel ridge north of the 161 area. This is marked with a scattering of cairns, which are augmented at the beginning of each expedition with reflective markers (collected in again at the end of the expo).
Follow the usual path from the Bergrestaurant car park to the Schwarzmoossattel. Rather than contouring around the base of the Nase as for old Top Camp, strike out to the right across the patch of boggy grass. From here, various variants of the path lead past the entrance to Bräuninghöhle (1623/82) and continue northwards to Laser Point 5.
Shortly after this is the beginning of a patch of bare limestone slabs, clearly visible from Top Camp, which marks the highest point of the route. The unmistakable arched entrance of Hauchhöhle marks the end of this section, and from here a slightly confusing broken area dotted with patches of dwarf pine brings one out at the entrance to Steinbrückenhöhle.
