A demanding climb, but a beautiful one. It offers an interesting alternative to the Montaud route to reach the Mortier tunnel, as it avoids the landslide. The first part (around 5km), which is the same as the ascent to Ezy, is tarmac. From the hamlet of Trucherelle, take a forest track to the top. The track is passable, but in poor condition in places (especially towards the last few hundred metres), so avoid road bikes. A gravel bike will do fine, however.... read more

A demanding climb, but a beautiful one. It offers an interesting alternative to the Montaud route to reach the Mortier tunnel, as it avoids the landslide.

Ascension exigeante, mais très belle. Elle offre une alternative intéressante à la route de Montaud pour atteindre le tunnel du Mortier, puisqu'elle évite l'éboulement.
La première partie (environ 5km), commune à la montée d'Ezy, est goudronnée. Au hameau de Trucherelle, on emprunte une piste forestière jusqu'en haut. La piste est carrossable, mais en mauvais état par endroit (surtout vers les dernières centaines de mètres), donc éviter le vélo de route. Un gravel fait parfaitement l'affaire cependant.
