A trail that winds its way through blueberry bushes in a magnificent spruce grove and among alpine meadows, with a magnificent view of the entire Mont Blanc range.
Set out to explore the Chalets de l'Avenaz: to begin your adventure, head to the Lezaive d'en Haut parking lot. From there, a well-marked trail will lead you through the forest to Les Plaines, where picnic tables are available for a short break.
Then continue toward the Chalets de l'Avenaz: this traditional alpine pasture, nestled in the heart of the mountains, is the perfect spot to admire the surrounding peaks.
Your path will eventually lead you to the Col de Jaillet, offering breathtaking views of the valley and the neighboring mountain ranges.
Suitable for hikers at the orange level (fairly difficult), this trail is also an excellent choice on hot days, thanks to its elevation and shaded areas.
Update as of June 3, 2026: Roadwork on the forest road toward Les Plaines is scheduled through Friday, July 3. This road will therefore be closed during the work. To access your route, you can take the Cornillon trail, either uphill or downhill. Contact Cordon Tourisme for more information.
Map available from the tourist office to discover these and other trails.
Whatever your hike, remember to pack cereal bars, plenty of water, sunglasses, sun cream, a small first-aid kit, and clothing suited to the season and weather forecast.
This itinerary can also be done accompanied, by hiring a mountain leader.
