From the parking lot near the cross-country ski center of Laghetti, ascend a short stretch along the state road before leaving it shortly after to take the old route of the Roman road on the right (local signs - CAI 161). You climb for a long stretch with a steady gradient towards the tollhouse, which you do not reach, turning right at the signs for Casera Pal Piccolo. The path becomes steeper and climbs through the beech forest, emerging on the meadows of the war chapel, near the former war cemetery of Pal Piccolo.
Continuing uphill, shortly after, turn left onto trail 401C of the Carnic Porters. The military engineering work ascends hairpin bends along the southern faces of Pal Piccolo, reaching the Cantore shelters and the iconic Cavernone. Then descending through green areas, the path reconnects to the main trail and continues to climb, passing the monument dedicated to the Financier Macchi, reaching the state border with the arrival of the Austrian cable car. Now turn right, among the barracks of the steep northern face, and shortly reach the summit with the large cross of Pal Piccolo.
Following the trench in a southward direction, you pass the Austro-Hungarian and Italian works, then return along the 401C trail markers to the next crossroads.
After descending again to the ascent route, in sight of the Cavernone, return to the valley on the same path.
