Sambock e sentiero 66
Very challenging itineraio, more uphill than downhill actually, since the path 66, known for its difficulty, has been almost completely flattened, in fact only a few challenging sections with roots and boulders are left, in addition to the final part.
The climb is long but not particularly challenging until the end of the pedaled part, but then there is a half-hour to be done with the bike on your back on very difficult ridges and chained sections.
This leads to the summit of Mt. Sambock, with beautiful views. From here superflow descent on trail 66, with some challenging sections, especially the last part, down to the valley. Alternatively, from the last alpine hut go up the forest road to the left and then push to the top of Sambock on the descent trail, definitely saving time and energy.
