"Oxygene 74 is a small hiking association which holds hikes every Sunday throughout the year, with snowshoes in winter. The hikes are for fit hikers, and last for five to nine hours. You need to register beforehand, details on forthcoming hikes are on the Website (in french) or on glocals. Starting point is usually at the French side of the border in Moillesulaz. There is a small registration fee. I am one of their animators/guides."
