Placette Pass

Highlight • Mountain Pass

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.

Very peaceful walk on the Via Chartreuse from the gorges of Crossey to Entre-2-Guiers. I saw 1 passage under 30-40cm of water in June 2024 during the heavy rain episodes
