Starting from the refuge in the Gardeccia site, take the path n.583 next to the wooden bridge and continue along the walls of the Larsech Group.
Through the part equipped with metal ropes and some iron pegs, you reach the Passo delle Scalette which invites you to enter the wild and little-frequented Val di Lausa, up to the homonymous pass located at 2700 m.
Going down to 2550 m, you come to the junction which, on the right leads to the Antermoia basin and the homonymous shelter. On the left following the path n.584 you go up to the Antermoia Pass at 2769 m. You reach the Principe Pass and then along the Vajolet valley you return to the refuge.
A rather long circular excursion, very beautiful from the point of view of the landscape.
