If you are from Asiago, to reach the Campolongo Refuge,simply followthe SP349 towards Vicenza and then continue on to the SP78 towards Roana and Mezzaselva. Once you reach the latter, take Via Verenetta (on the right) and follow the directions to the Sanctuary.
Those who arrive from the plain, on the other hand, can easily reach the refuge via the Piovan Road,which from the Valdastico quickly climbs to Rotzo. Exiting theA31 motorway at Piovene Rocchette, you have to follow in the direction trento and further forward turn right in the direction of Pedescala / Rotzo.
