Mazzin - Val de Udai - Camerloi - Val de Dona - Res. Solaria - Mazzin

The itinerary runs through the Val de Udai and Val de Dona, two picturesque, secluded and wild places located at the north-eastern foothills of the Catinaccio group. The valleys meet at the vast and pleasant "Camerloi" meadows, from where the trail continues to Lake Antermoia.

From the centre of Mazzin go up along "Strèda dò Ru"f and then continue along the forest road called Val de Udai (path no. 580). The road climbs fairly steeply along the stream of the same name. There is a bridge which takes you over to the other bank, and then the road becomes very steep indeed, just before meeting up with path no. 579 which comes from "Ronch" (Muncion). Shortly after this you come to a flat section where you will have to cross the brilliantly white scree which runs across the pathway. Next you cross the stream and then you go back into the woods to follow the rough track. The "Zocol" face is visible together with the spectacular waterfalls known as "l Pis" (or "Soscorza") and the "Spina da Lèch", and eventually you pass right under the rock face. Now the path eases off, and a series of bends help to gain altitude comfortably. You cross the stream once more and then get to the "Pian de Udai", a basin which boasts a good number of flowers. Once again the climb becomes taxing and the path crosses the stream several times. The rocks to the left are volcanic in origin and the gullies on the right come down from the "Dò Ciuril" mountain. The final climb brings you out on the upper Val de Dona. You return by descending the Val de Dona to the right (path no. 577). At the junction of the forest road coming from Mazzin, you follow it as you exit the forest near Residence Solaria.
