Thonon-les-Bains ⇒ Chamonix
We have arrived in the Alps: the highest mountain range in western Europe. In this first part of the Alps, we walk from Thonon-les-Bains on Lake Geneva in almost 155 kilometers to Les Houches, near Chamonix at the foot of the Mont Blanc massif.
The Alps has the highest peaks and deepest valleys of this route to Nice. This is the most challenging section of the GR5. Because of the altimeters, but also because of the long stretches with no stores, campsites or water points. This makes planning extremely important and fitness will undoubtedly be put to the test…. But how wonderful these stages through the high mountains of the Alps are. The beautiful scenery and phenomenal views make every step worthwhile!
