The route wends its way alongside the river Saane before climbing to the L'Etivaz plateau, famous for its cheese L'Etivaz AOP. The rocky nature reserve of La Pierreuse in the Gruyère Pays-d'Enhaut Regional Nature Park affords a rich variety of impressions.
Setting off from the hot air balloon Mecca of Château-d’Oex, you will walk along the river Saane to Gérignoz. There is a steep climb up to the nature conservation area of La Pierreuse. Surrounded by eroded mountain peaks, you will walk to the highest point at 2,000 metres. After that comes a steep descent to L’Etivaz.
