Carry on downhill on track n° 402 until you reach track n° 423, taking the deviation on the left to the Rifugio Col Gallina mountain lodge.
From here, cross the road and go downhill on track n° 424 and then take track n° 440 towards Cinque Torri. Continue uphill until you reach the picturesque Rifugio Averau mountain lodge, set between Mount Averau and Mount Nuvolau. From here, go downhill along the dirt road until you reach track n° 452 on your left, and follow this to the Giau Pass.
Having crossed the road to take track n° 436 towards the gullies Forcella Giau and Forcella Ambrizzola, continue on track n° 434, crossing the wild Mondeval valley until you reach mount Croda da Lago, with its distinctive mountain lodge and the enchanting Lake Federa.
