The Gran Bosco dei Fontanassi is a jewel of biodiversity located between Treviso and Quinto, where the phenomenon of springs gives life to an enchanted landscape. In this precious wetland of the Parco del Sile, water spontaneously emerges from the earth, creating crystal-clear pools at a constant temperature. Walking among black alders and willows, it is possible to spot herons and kingfishers in a regenerating silence. It is an ancient stretch of forest that testifies to the original richness of the plain.

A magical place, nestled in the middle of the woods, with absolute silence. A stop on the benches to gaze at the Fontanassi, underground spring waters, is a must.

Unlike the classic Cansiglio loop, from Crosetta we descended towards Fregona for about 500 meters until reaching the 14% climb that leads to the Malghe trail. The route runs through Friuli Venezia Giulia, in the municipalities of Caneva and Polcenigo, through pastures. At km 7.41, we turn left to reach the Candaglia Forestry House and then resume the classic tour. We then reach Sant'Anna and Broz. From there, we climb back up to Campon to join the Taffarel.
