From Prato down the road we crossed the river and started a long ascent on the paved road to passo Carnizia. Up there are a few huts where you can make a nice rest and there also a unpaved road takes off at the right to the mountain crest (CAI 739). Finally you reach a small pasture where you go into the woods at your right still following 739. Partly very nice single trail with a few pushing passages. Down at the state road take a right turn to Passo Tanamea and follow the raod 636 down to Tarcento and finally we reached Marsure di sotto!
