Road of the 52 tunnels of Pasubio, from Bocchetta Campiglia and Passo Xomo

Road of the 52 tunnels of Pasubio, once you have reached Passo Xomo, shortly after there is a large car park at Bocchetta Campiglia where you can leave your car.
The road of the 52 galleries (or road of the First Army) is a military mule track built during the First World War on the Pasubio massif, in north-eastern Italy. The road winds between Bocchetta Campiglia (1,216 m) [1] and the Pasubio gates (1,934 m) [2] crossing the southern slope of the mountain, not reachable by Austro-Hungarian artillery fire, characterized by pinnacles, deep gorges and perpendicular rock faces, with arrival at the Achille Papa Refuge.
