Between Mont Blanc and Lake Geneva, on the border between France and Switzerland, lies a group of mountain ranges that have remained hidden from the rest of the world: Dents Blanches, Dents du Midi, Tenneverge, Mont Ruan. This is an area strongly shaped by the folding of the Alps, with surprising landscapes ranging from lunar deserts to high-altitude lakes, waterfalls and forgotten mountain pastures. Here, there is no human pressure, just a wild, unspoilt nature that only hikers can discover. Leaving from one of the largest natural cirques in the Alps, leave civilisation behind for a perfect 6-day loop of spectacular mountain hiking, passing through some of the most isolated refuges in the world, for a complete break from the world.
