This route is categorized as a difficult mountain bike ride. It demands very good fitness and advanced riding skills. You should be prepared for technical sections, rated from STS S2 to S6, and some portions where you may need to push your bike.
The trail offers a diverse mix of surfaces over its approximately 25.8 km. You'll encounter significant stretches of singletrack (9.43 km) and natural paths (12.3 km), along with unpaved sections (22.1 km). There are also rocky segments, forest tracks, and shorter stretches of gravel, asphalt, and paved surfaces. The route ascends through dense forests, transitioning from larch to ancient cembro pine trees.
The route leads to the stunning Lake Orceyrette, a picturesque glacial lake at 1,927 meters, known for its clear waters. You'll also traverse the Bois des Ayes, a controlled forest biological reserve and Natura 2000 site, home to ancient cembro pines, some 400-600 years old. Magnificent views of the surrounding mountain peaks are a constant reward.
Yes, the route incorporates sections of several other trails. You'll ride along parts of Rouge Melezin, Grand Bois des Bans, Les Mines de Villard-St-Pancrace, and Le Clot de l'Ase, among others. It also briefly touches on longer routes like Durance à Vélo and Via Domitia.
Given its high altitude and challenging nature, the best time to mountain bike this trail is typically from late spring through early autumn (roughly June to September). Always check local weather conditions and trail status before heading out, as snow can persist at higher elevations into early summer.
While the Bois des Ayes is a natural reserve, dogs are generally permitted on trails. However, due to the ecological sensitivity of the area and the presence of wildlife, it is crucial to keep dogs on a leash at all times to protect the local fauna and flora, especially during nesting seasons.
No, there are typically no specific permits or entrance fees required to access the trails within the Réserve du bois des Ayes for mountain biking. However, as it is a protected area (controlled forest biological reserve and Natura 2000 site), please respect all environmental regulations, stay on marked paths, and practice Leave No Trace principles.
Specific parking information for this exact trailhead isn't detailed, but generally, access points for trails leading to Lac de l'Orceyrette and through the Bois des Ayes can be found near the villages of Cervières or Villard-Saint-Pancrace. Look for designated parking areas at the start of forest roads or trailheads. It's advisable to check local maps or komoot's tour planner for the most precise starting points and parking options.
The Bois des Ayes is rich in biodiversity. You might spot various bird species, including the European owl, Tengmalm's owl, and the black grouse. Keep an eye out for other forest animals, but remember to observe from a distance and avoid disturbing their natural habitat.
Absolutely! Beyond the stunning Lake Orceyrette itself, keep an eye out for the challenging Ascent to Mélezin and Singletrack Descent, which offers a thrilling ride. There's also a unique Downhill meadow fence section. The ancient cembro pine forests are also a highlight, with some trees being centuries old.
Given the route's difficulty and the potential for pushing your bike, consider starting early in the day, especially during warmer months, to allow ample time. The diverse terrain, including rocky sections and technical singletrack, means you'll want to conserve energy. Packing enough water and snacks is crucial, as amenities are scarce once you're on the trail.
Very satisfying trip for views, magical woods, dirt road easily pedaled. Stop at the buvette with blueberry culis tarts. This morning difficulty finding the start. Few people.
