A beautiful sporty hike to discover one of the sections of the GR5, but also the geological and natural sites of the Abondance valley.

This itinerary starts from the Alpage de Bise, classified as a UNESCO Geopark. Its landscapes offer a real journey through time, from the history of the formation of the Alps to the history of the people who lived in this mountain environment with their herds.

After a short climb through the pastures to the Pas de la Bosse (1816 m), you will continue with a long descent of 800m to the Chapelle d'Abondance with the Mont de Grange, the emblematic summit of the Chablais, as your sight.

At La Chapelle d'Abondance, you can stop and admire the beautiful traditional wooden farmhouses, whose vast surface area made it possible to meet the needs of the winter: sheltering men, their animals and the food reserves for each of them. You will also have the opportunity to stock up on cheese and other regional products at the "fruitiere" before climbing up the slopes of the Mont de Grange, a peak culminating at 2432 m and a Natura 2000 site. This reserve is home to numerous species: red deer, chamois, ptarmigan, black grouse, peregrine falcons... Keep your eyes open!

Your arrival at the Trébentaz Refuge will also be full of surprises, with a magnificent panorama of the Valais, Chablais and Bernese Oberland!
