This groomed trail through the vast expanses of the Plateau du Bourget stretches for almost 15 kilometers to Les Fonts de Cervières. Discover an exceptional and timeless site, a hike for lovers of wide open spaces.
From the Foyer de ski de fond parking lot, walk 100m up the road and cross the bridge.
Return to the village on the main road. At the top, after the bend, pass the Ferme découverte "La Maison des Bêtes à laine" and continue straight on.
Continue along the snow-covered road that serves as a snowshoe itinerary and cross the Mur des Aittes.
After the Mur des Aittes, the view opens out onto the vast snow-covered plateau of the Marais du Bourget. Continue on the track, which descends slightly and passes close to the hamlet of La Chau. Join the straight that crosses the Bourget marsh.
Pass the various hamlets on the plain.
Halfway along, the valley narrows. The trail continues for 5 kilometers to the hamlet of Les Fonts de Cervières.
Return by the same route.

Groomed trail
Please note that this particularly long route requires careful preparation.
- The telephone network is almost non-existent in this part of the valley.
- The Refuge des Fonts de Cervières is not open in winter.
- In the village of Cervières, there is a cross-country ski hostel where you can rent cross-country skiing equipment (alternating and skating), snowshoes, sealskins for cross-country skiing, sledges... Also tourist information and ski pass sales.
The Fonts de Cervières trail is generally groomed from February onwards. Before this period, the trail is not secured and access is more difficult.
Progress on snow-covered terrain is far more demanding than in summer. It requires special equipment and knowledge of mountain hazards.
- Consult the weather forecast bulletin
- Avalanche risk assessment bulletin
-Consult guidebook recommendations
- Make sure you have the right equipment, including avalanche transceivers, shovels and probes.
- Choose an itinerary suited to your physical condition
- Never set off alone.
