For those arriving at Calcata Vecchia and wanting to descend into the Treja Valley, I strongly advise against taking the marked path that is not on the road: it is a pedestrian descent that can only be done with a bike in hand, and not even easily. Descend following the main asphalt road.

The passage to Campagnano is excellent for a stop, water fountains and fountains with drinkable water, in the square there is a bar. The town is worth a visit. If you come from the waterfalls of Monte Gelato you will have to face a climb with a significant slope, there are 3 short hairpin bends.
