This is a difficult mountain bike trail, demanding very good fitness and advanced riding skills. It is both physically and technically challenging. Be prepared for sections where you may need to push or even carry your bike, especially on the steep ascents to Pas de Lona and Col du Cou. Some parts are exposed, making it suitable only for experienced riders.
The terrain is varied and demanding. You'll encounter steep climbs, such as the initial ascent to Alp Orzival, which includes short push sections. After the climb to Pas de Lona, the route features steady ups and downs before another very steep climb to Col du Cou. Descents can transition into flowing singletrack, but the initial entry from Pas de Lona is described as very steep and potentially slippery due to loose stones. Expect narrow paths and some excellent access trails through terraced fields.
Riders are treated to exceptional landscapes and expansive views of the Valais mountain world. The route takes you through remote alpine areas, often above 2500 meters. Highlights include views of the azure blue Lac de Lona, beautifully nestled within the mountains, and glimpses of dreamlike mountains with glaciers and numerous mountain lakes. You might also ride through larch forests and sunny mountain villages, with potential views of Valais' 4000-meter peaks.
The route starts from Evolène. Parking options are available in the village. For those using public transport, Evolène is accessible by post bus, which can also be a strategic option for longer tours incorporating the Pas de Lona to reduce altitude gain.
The estimated riding time for this 29 km route with over 1600 meters of ascent is approximately 4 hours and 25 minutes. However, given its challenging nature and the potential for pushing sections, it's advisable to allow extra time for breaks, enjoying the views, and navigating difficult terrain.
The best time to ride this trail is typically during the summer and early autumn months, from late June to September or early October. This ensures that most of the snow has melted, and the weather conditions are generally more stable and favorable for high-alpine mountain biking.
Generally, there are no specific permits or entrance fees required for mountain biking on public trails in the Val d'Hérens region. However, it's always good practice to check local regulations or any specific rules for protected areas you might pass through. Respect private property and agricultural land.
While dogs are generally allowed on trails in the Valais region, this particular route is very demanding for both rider and bike. The steep, exposed, and technically challenging terrain, combined with significant elevation changes, might not be suitable for all dogs. If you bring your dog, ensure they are fit for such a strenuous journey and keep them on a leash, especially in alpine pastures or near livestock.
Yes, the route intersects with several other paths. Notably, it covers significant sections of the 25-Alpine Passes Trail (56%) and the 04-Tour pédestre du Val d'Hérens (43%). You will also encounter parts of the Volvovron - L'A Vieille, L'a Vieille - Pas de Lona, and Chemin de Volovron trails.
Absolutely! Key highlights include the challenging Steep Ascent from Elson, the rewarding Pas de Lona itself, and exhilarating Singletrack sections. You might also find a Mountain restaurant or hut along the way, such as the Becs de Bosson hut overlooking the pass, offering a chance to refuel and enjoy the views.
Given the high-alpine and demanding nature of this trail, pack essentials for a full day in the mountains. This includes plenty of water and snacks, appropriate layers for varying weather conditions (even in summer), rain gear, a first-aid kit, bike repair tools, a helmet, gloves, and sturdy mountain biking shoes. Sun protection is also crucial at high altitudes.
