A pleasant climb through picturesque villages. The view is nice. The last 6 km are more difficult with a positive difference in altitude of 550m. The road is narrow and in poor condition as motor vehicles are not allowed. Beautiful viewpoint at Mont Vial.... read more

Mont Vial has to be earned: the last 6km don't drop below 9-10% and the very last one after the pass includes short descents followed by as many ascents. And all this after a 20km climb from the bottom. These last 6km are car-free and on a rough surface, with the road at the end in average condition (holes, gravel and pebbles). As a result, the descent is cautious.

Le Mont Vial se mérite : les 6 derniers kilomètres ne descendent pas en dessous de 9-10% et le tout dernier après le col inclus de courtes descentes suivies d'autant de remontées. Et tout ça après 20km de montée depuis le bas. Ces 6 derniers kilomètres sont sans voiture et sur un revêtement rugueux avec sur la fin une route en état moyen (trous, gravillonset cailloux). Du coup, la redescente se fait prudemment.

A fine climb. The first 2/3 are rolling, the last third attacks the calves! If you're looking for peace and quiet, this is a good idea, as there really aren't many people on the road (no one for me).
Stop off at the Bonson grocery shop at the entrance to the village, they're really friendly.
Watch out for the heat in summer, which is particularly tough down in the Var plain.

Belle ascension. Les premiers 2/3 sont roulants, le dernier tiers attaque les mollets! Si vous recherchez du calme c'est le bon plan, il n'y a vraiment pas grand monde sur la route (personne pour ma part).
Un stop à l'épicerie de Bonson, à l'entrée du village, ils sont super sympas.
Attention à la chaleur l'été, particulièrement éprouvante en bas dans la plaine du var.

Montée agréable et traversée de villages pittoresques. Le point de vue est joli. Les 6 derniers kilomètres sont en revanche plus difficiles avec un dénivelé positif de 550m . La route est étroite et en mauvais état car interdite aux véhicules à moteur. Beau point de vue au mont Vial.
