Follow the footsteps of the Walser through this “landscape of national significance”: the winding route from Thusis through the Viamala Gorge is as varied as it is dramatic. It’s among the absolute high points of the tour to the San Bernardino Pass, next door to the Splügen Pass. The plateau, with its moors and small lakes, gives this unspoilt Alpine landscape its special charm. As do the marvellous views, of course, like the one of the Val Moesano. On the south side, a detour to the sunny, secluded Val Calanca is worth the trip. The drive alone is a fabulous experience on this Graubünden tour.
