Hold your breath and board this train that climbs, climbs, and climbs some more. Nothing scares it, neither the steep slopes nor the snow. At the Rochers-de-Naye, at over 2,000 metres altitude, what amazing scenery! Lake Geneva in all its glory. Don’t leave the place without saying hello to the marmots, the mascot of the Alps. A tip: it is said that this is where the real Santa Claus spends the winter.
