On a sunny autumn day I made a beautiful hike over the Ducanfurgga. By postal bus I drove from Davos to the Sertig Valley. I started walking in Sertig Sand. 

The steepest part of the trail is behind me at 2,480 meters. From here you have a beautiful view over the Ducan Valley and you can also see the Fanezfurgga Pass (2,580 meters), where you can hike to the village Davos Monstein.
