Col de la Croix de Cœur and Col du Lein Loop

While the loop is often associated with Martigny as a base, many cyclists start from Le Châble, which is easily accessible by train from Martigny. If you choose to start directly from Martigny, you'll find various public parking options within the town, though specific trailhead parking for this route isn't designated. Consider parking near the train station for convenience.

You'll encounter diverse terrain, from wide, steady climbs to narrow, steep roads. While mostly paved, some sections, particularly on the descent from Col de la Croix de Coeur and at the summit of Col du Lein, may have rough surfaces or a few hundred meters of hard-packed gravel. A road bike with 28-32mm tires is recommended for comfort and grip, and a gravel bike would be even more comfortable for these mixed sections.

The best time to cycle this loop is typically from late spring through early autumn, roughly May to October. During these months, the mountain passes are generally clear of snow, and the weather is more favorable for high-altitude cycling. Always check local road conditions and weather forecasts before you go.

This is a road cycling route, so dogs are generally not permitted to run alongside cyclists for safety reasons, especially on busy roads or steep descents. If you wish to bring a dog, it would need to be securely transported in a bike trailer designed for pets, adhering to Swiss regulations for animal transport.

Yes, sections of this route briefly intersect with or run parallel to several other paths. Notably, you'll find parts of the Rhône-Route, WHR Stage 5 Le Châble – Clambin – Cabane du Mont Fort, and the Chamonix-Zermatt High-Level Walker's route. Other smaller local paths like Chemin du 700ème and Promenade de la Dranse also cross the route at various points.

The Col du Lein is considered a 'hidden gem' because it offers a tranquil cycling experience on generally small roads with very few cars. It provides expanding, less-traveled views over central Valais, stretching from Martigny to Sion, and a sense of adventure away from more frequented routes.

Given the difficulty and length, you should bring plenty of water, energy gels or bars, and appropriate cycling attire for varying mountain weather. Essential gear includes a repair kit, spare tubes, a pump, and a fully charged phone. Don't forget sunglasses, sunscreen, and a light jacket for descents or changing conditions.
