From Prato all’Albero, where you can leave your car, take the forest road 00 to reach Capanna Marcone bivouac, which is always open. Continue straight to the crossroads, then go right where after about 30 minutes you will arrive at the La Serra mountain shelter. Follow the signs to I Diacci and go down on the right until you find the trail to Mulino-Diacci-Sambuca on your left. From now, you find a few fords until you reach the river Rovigo. After the fords, you'll find the old Diacci mill on the left.You can continue to the I Diacci Refuge, where you can sleep and taste a tortelli di patate and other specialties. Don't miss a stop at the Abbraccio Waterfall, it's not far from the mill and is a large waterfall that forms a stone embrace. It's very impressive when the water is flowing heavily and it's even possible to pass behind it.
