Castel Pietra rises above the town of Tonadico, erected on top of a huge erratic boulder (from which its name originates) on the Torrente Canali, a privileged position from which to control the road that connects Primiero with Agordino.
To access the ruin, you must be accompanied by an Alpine Guide or a Medium Mountain Guide (AMM) who must request authorization in advance at the ApT office of Fiera di Primiero providing all the details of the accompanied group (maximum 10 people at a time).
WARNING: DUE TO WORK ON THE STRUCTURE, THE CASTLE RUINS WILL NOT BE VISIBLE DURING SUMMER AND AUTUMN 2026.
