The climb from Malga Grassi to Rifugio Pernici is a long and demanding one, but it pays off with a spectacular crossing leading to Bocca Saval, which hosts a military hospital from the First World War (the whole area is brimming with history).
The descent takes us back to a more rural environment with pastures and alpine huts; we come across the Malga/Baita Gelos and Malga Grassi, from which we descend to reach the chestnut grove of the San Martino archaeological zone (taking time out for a visit). From the archaeological zone, we then return briefly to the village of Campi.
Water points: if you're passing through in late spring/summer, fill up at Campi where there are a few fountains.. Afterwards you will only encounter the stopping points of Rifugio Pernici and Malga Grassi (check the opening periods).
