The itinerary is very demanding and recommended only for experienced hikers. It can be completed in one day, but considering the length and the difference in height we recommend splitting it into two stages by using the bivouac at "In la Piana".
The itinerary starts from the locality of Malesco where we take the road to the Loana valley; we park the car and proceed on the path, crossing the Rio Loana and following the trail that heads towards the bottom of the valley, to then climb quickly into the woods.
We continue on the mule track and arrive at Alpe Cortenuovo at an altitude of 1792 metres; we continue to Alpe Scaredi where we reach the bivouac of the park.
From Scaredi we descend and then climb up to Alpe Portaiola going into the beech woods to the bottom of the valley to cross the Rio Valrossa. After crossing the footbridge we continue with a slight ascent to reach the meadow of the mountain pasture at In La Piana where the three bivouacs of the park as well as the barracks of the Carabinieri Forestali (Forest Rangers) are situated.
We proceed as far as a stream and climb up to Alpe Serena; the path climbs rapidly in sharp bends to the Colma di Premosello at an altitude of 1728 metres. From the Colma we descend to Alpe La Motta and then to Alpe La Piana. From here on an asphalted road we reach the basin above Colloro.
