Small nice pass not too bad in the direction towards Voreppe. It allows the switch to the valley and an easy return to Grenoble. Please note that there may be road traffic.

Departure 7:30 a.m. to join Adrien in St Lau.
Relaxed climb to the Col de Porte with a break ☕ at Raph&Vero.

With Adrien between St Lau and the Col de Porte.
