Arolla, Lac bleu, geologic Route

Arolla–Louché (Lac bleu)–Les Haudères

PostBus takes you to the stars. 13 magnificent PostBus hiking suggestions.

Starting in Arolla in the direction of the Hotel du Glacier, we hike to the lake «Lac Bleu». The trail passes the alp «L’Etoile» to «Les Mayens de la Coûta». There we have a great view of the Val d’Hérens, the Mont-Collon, the Veisivi massif, and the Tsalion ridge. We then continue to «Les Haudères».

The upward climb is classed as more difficult than the decent. Figures provided for hiking times refer solely to the actual hiking time without pauses.

Before commencing a hike, we recommend you refer to the public transport timetables and integrate these in your planning. Equally as important is to take along a hiking map of the visited region, good comfortable hiking shoes, some form of rain protection as well as warm clothing. Please be informed concerning the opening hours of snack stands and restaurants. For group travels we advise you to make reservations in advance.
