Overall, a smooth and comfortable gravel route. A few sections are a bit bumpier. Certainly the best option for a leisurely climb towards the Vercors mountains, safe and secure, in a beautiful setting and somewhat shaded when the sun is beating down.

Nice place to cool off on a small pebble beach just before the bridge when it's a heatwave!

Not long, it's flat along a small irrigation canal, shaded, educational information panels, particularly on geology, recommended with young children

Not far from Vorreppe, the Isère River flows around the Bec de l'Échaillon, which overlooks it at an altitude of 622 meters. This meander offers a magnificent view of this Vercors peak.

Very peaceful walk on the Via Chartreuse from the gorges of Crossey to Entre-2-Guiers. I saw 1 passage under 30-40cm of water in June 2024 during the heavy rain episodes
