The best places to escape the heatwave in Haute-Savoie

When the thermometer spikes and the air becomes unbearable, Haute-Savoie hides true secret refuges… Places where you can breathe deeply, where the sound of water and the shade of cliffs replace the overwhelming heat of the valleys. Some are hidden deep in the mountains, others nestled at altitude or carved into the rock, like this spectacular via ferrata equipped with suspension bridges and zip lines..
Here is a cool itinerary for a summer in the open air… and far from the heatwave.

1. Cliffs that filter the light – The Gorges du Fier (Lovagny)

Here, a suspension bridge clinging to the cliffside takes you above a powerful torrent. In this narrow gorge, the sun barely penetrates, and the air remains naturally cool.

2. An icy cave… and a waterfall – Seythenex Cave and Waterfall (Faverges)
