SI E52N

A medium-length stage with minimal elevation gain that crosses the slopes of the high Antrona Valley along the characteristic tunnel between the dams of Lake Cingino and Lake Camposecco. From the bivouac, you cross the dam and head to the tunnel entrance. This is a 2 km long gallery, about 1.80 meters high, which may be flooded with a few centimeters of water and is illuminated by timed lights; it is essential, however, to carry a headlamp. After exiting, continue to Lake Camposecco (which has a bivouac with 12 spots) where a steep ascent begins, aided by a chain, to the pass of the Coronette di Camposecco. On the descent, you reach the bottom of Val Loranco, where the biggest challenge of this stage is crossing the stream (a suspension bridge is being planned). You then start an ascent that leads to the Andolla Refuge.
