Good running climb. Before col de Vence, there is a small descent that this profile does not really reflect.
Goed lopende klim. Voor col de Vence zit er wel een kleine afdaling die door dit profiel niet echt wordt weergegeven.
One of the many ways to reach the Porte pass, and which has the advantage of cumulating four passes, not less, in one single ascent, since before reaching the Porte pass you will have crossed the passes of Clementières, Vence and Palaquit, in that order! :-)
It is also a little less frequented than the standard ascent by Grenoble. That said, as for this one, it is better to avoid rush hours.
The part between Clémencières and Vence is the less frequented, relatively easy and pleasant to walk.
Une des nombreuses façons d'accéder au col de Porte, et qui a l'avantage de cumuler quatre cols, pas moins, en une seule montée, puisqu'avant d'arriver au col de Porte on aura franchi les cols de Clémencières, de Vence et de Palaquit, dans cet ordre ! :-)
Elle est également un peu moins fréquentée que l'ascension standard par Grenoble. Ceci dit, comme pour celle-ci, il vaut mieux éviter les heures de pointe.
La partie entre Clémencières et Vence est la moins fréquentée, relativement peu pentue et agréable à parcourir.
