It's not the steepest slope, but the usual road at the end after Miribel. Still splendid scenery over the Chartreuse.... read more

It's not the steepest slope, but the usual road at the end after Miribel. Still splendid scenery over the Chartreuse.

Ce n'est pas la versant le plus raide, on retrouve la route habituelle sur la fin après Miribel. Toujours des paysages splendides sur la chartreuse.

Done on March 4, 2026.
Apart from one or two steep sections well represented on the profile, the climb is on the whole fairly smooth and takes place on a beautiful road with no shade except on the final stretch through the woods.
The scenery is nothing out of the ordinary.
Traffic on this Wednesday, almost late in the morning, was moderate, but I think it must be heavier in summer, as this is a main road.

Fais le 4 mars 2026.
À part une ou 2 portions raides bien représentées sur le profil, la montée est dans l'ensemble assez roulante et se déroule sur une belle route dénuée partie ombragée sauf sur le final dans les bois.
Rien de bien extraordinaire côté paysage.
La circulation ce mercredi presque en fin de matinée était modérée mais je pense qu'en période estivale elle doit être plus dense car c'est un axe principal.
