A cosy mountain restaurant in Graubünden.
Situated 1,861 metres above sea level in the Sertigal mountains of Davos-Klosters, Zum Bergführer serves up hearty mountain fare from November to April, and then during the summer months (May-Oct). The restaurant is housed in a 400-year-old mountain hut and on sunny days, you can enjoy the crisp air on the terrace as well as amazing mountain views. Arrive via cross-country ski, hike or, for those feeling less adventurous, by road.
