Combined with the Caneva Castle (another highlight) this proposal takes you around the source of the Livenza.
Road without difficulty, you pass through the woods until you reach the center of Polcenigo, a very beautiful town with historic streets that survived the earthquake of 1976.
You go back under the slopes of Cansiglio until you skirt the Livenza resurgence.
I recommend entering the small road of the resurgence, passing in front of the church, taking the time to enjoy the freshness of the place and perhaps returning for a local walk.
Worth it, mystical place.
