You can get to Alla Casetta either from Feltre or Cesiomaggiore. GPS can be used until “via strada delle negre”; after that, switch it off and open your eyes! Follow the wooden signs at each crossroad. (GPS doesn’t recognize house number 10 and La Casetta is not close to number 12!)
Although La Casetta is not in the mountains per sae, it is mountain territory. It is common to find windy roads which are not as wide or smooth as urban ones. Please drive carefully!
