Hard and hot... But a beautiful panorama at the summit

A very quiet and pleasant road. On the Chambéry side, a good part is in the shade, the slope of the main road is rather constant around 7-8%. On the Novalaise side, the mineral aspect with the cliff is more present in the middle of the climb. This side is quite steep with kilometers at 8-9%. On each side, 1 belvedere offers a breathtaking view of Lake Aiguebelette (approx. 2 km from the summit) and on the other side of Chambéry, the Bauges, Belledonne, the Chartreuse (500 m from the summit). The summit is in the forest.

Great, remember to take something to cover yourself with depending on the time of year…. Climbed in April, there was still snow at altitude. The descent was cool

Please note: Col de Plainpalais and the descent to Le Noyer are not possible between May 14 and 17. The road is currently being completely resurfaced. The road surface will be even better.
