A trail where you can admire the fascinating, distinctive 20th century architecture of the Les Arcs resorts set against beautiful natural scenery.

This trail gives you an insight into the rich religious past of Val d'Isère and its hamlets, through the seven chapels that you'll pass along the way. There used to be more, but many have since disappeared, either owing to the wrath of the mountain (avalanches, floods) or for want of funds to maintain them. Le Manchet hamlet still harbours a few ruins that have survived over the centuries.
Setting off from the resort of Val d'Isère, part of the circular route runs along lovely green sections, between woodland and the Isère riverbanks. Vanoise National Park is just beyond the mountain pastures you'll be riding through. On the final leg, by Le Fornet, you'll cycle over a magnificent bridge straddling the rushing River Isère.


Setting off from Nancroix, make your way up towards the Col de la Chal (2,465m) along a lovely track meandering between woodland and highland pastures. From the mountain pass, you'll reach the Bike Park of Les Arcs before beginning your descent along a series of enjoyable (single track) paths as far as the Arc 2000 resort. The route then carries on to Arc 1600 via a steady, gentle woodland path with sweeping viewpoints over Beaufortain and Mont-Blanc. After a short uphill climb to Arc 1800, continue on to Peisey along the wonderful Route des Espanols (Spanish Road). From Peisey, make your way down as far as Nancroix, taking care over the last downhill section, which is a little steeper and more technical.

Altimetric profile


Rando Vanoise has been designed to help you pick and choose your outings, but cannot be held liable where they are concerned. The mountain offers up a wide range of routes and trails for cyclists of all levels, but remember, it is a living, unpredictable environment and it is important that you head out suitably equipped. Ask advice from cycle rental operators.
If in doubt, you can take an introductory lesson in how to ride an electric bike with an instructor.

If you see a herd ahead, slow down and go round it. If there is a patou, a guard dog, climb down from your bike and walk, pushing it alongside you. Avoid making any sudden or aggressive gestures towards the dog and move away from the herd slowly and calmly. The dog will only be checking that you do not pose a threat to its herd. Respect the parkland and close gates behind you after you've gone through them.

The mountain is living, please respect it by staying on the paths and tracks.

    Arc 2000

    Overlooked by the Aiguille Rouge peak (3,226m), Arc 2000 was designed like a high mountain refuge by its architect Bernard Taillefer. The roofs, which look like ship's sails, mirror the slopes and peaks of Mont Blanc. An idyllic playground for freeriding and extreme sports, during the Albertville Olympics (1992) the resort hosted the speed skiing competitions.

  • Architecture

    Arc 1600

    Inaugurated in 1968, the resort of Les Arcs provided an exciting testing ground for many architects, the likes of Charlotte Perriand, Guy Rey-Millet, Gaston Regairaz and Bernard Taillefer. They have designed buildings in altogether innovative shapes, such as the slanting façades of the Cascade residence. The glulam structure of the Dome, designed by Pierre Faucheux, would be chosen as the logo of the Les Arcs resort. For two decades, Charlotte Perriand shared her brilliant, cutting-edge ideas with the multidisciplinary team (architects, urban planners, landscapers, carpenters and technicians among them) that created Les Arcs out of a pristine area with almost no urbanisation. Still today, this collective achievement inspires a mix of reactions, often admiration, and continues to pay undeniable witness to a time of great freedom when creative and visionary mindsets set the stage for all manner of big and bold designs. The award of the “Heritage in the 20th century” label recognises Les Arcs' unique place on the French architecture scene.

    Arc 1800

    Inaugurated in December 1974, Arc 1800 comprises four village resorts perched on the edge of the forest overlooking the Haute-Tarentaise Valley below. Its innovative architecture follows the slope to free up space and provide views over the surrounding mountain ranges. In winter, this is where Paradiski, the world's second largest ski area, converges. In the summer it is buzzing with all kinds of outdoor activities including hiking, paragliding, archery and cycling!

  • History

    Route des espagnols (the Spanish Road)

    With Italy right on the doorstep of the Haute-Tarentaise, just the other side of the Col du Petit Saint-Bernard mountain pass, the region needed careful surveillance and protection. This is how a series of barriers, defence and observational structures came to be planned and built at the end of the 19th century. But the construction in 1913 of the Courbaton and Les Têtes batteries, to counter the rise in Fascism and Nazism, meant wider access than the lone track running from Montrigon to Courbaton had to be provided. So two strategic roads were opened up, one from Peisey-Nancroix and the other from Hauteville-Gondon, to enable men, provisions and ammunition to reach the batteries… These structures were built by veterans of the Spanish civil war who, on fleeing the advancing pro-Franco troops, crossed the border in early 1939 and were rounded up in Argelès-sur-Mer internment camp. Supervised by army officers based in Bourg-Saint-Maurice, they were used all year round as additional labour for the defence and road construction works. This explains why one of these access roads is still referred to as "the Spanish Road" to this day.
