From the centre of Mazzin (1,372 m) go up along Strèda dò Ruf and then continue along the forest road called Val 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. 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 di Dona (2 hrs 30). There is a choice for the return: you can either follow walk no. 2/o (path no. 577) to Fontanazzo (Fontanac) (1 hour 45), or you can climb to the head of the Val di Dona cutting diagonally across the Camerloi meadows to reach the Pas de le Ciaréjoles (2,282 m), and then down to Campitello (Ciampedèl) by way of the Val Duron (paths no. 578 and no. 532) (2 hrs 30).

Safety information

For your hikes in mountain always choose itineraries in accordance with your technical and physical abilities. Consult maps of the area to visit and check the best way to follow. If you walk in group including slower hikers, always calculate longer average times to cover the distances.

Preferably do not hike alone in mountain. Otherwise tell someone the itinerary that you are going to follow and let him know when you are back.

Check the weather forecast and, while hiking, constantly pay attention to the evolution of the weather.

If you do not feel safe, give up. In mountain, sometimes, it is better to surrender than to face the dangers deriving from bad weather conditions or from difficulties superior to one’s limits. In advance look for alternative itineraries to get back.

Bring rubbish back with you. Respect the flora and fauna. Remain on the marked tracks, avoiding to follow shortest ways, in order to avoid causing damages to vegetation and the territory. Respect local cultures andtraditions, always bearing in mind that you are a guest.
