Avoid taking this path, it is dangerous, very steep and slippery with pebbles.

Don't forget that even if it's in the mid-mountains, you need to be equipped for the weather, good shoes, and good physical condition.

The via ferrata of the Carret cave is rated extremely difficult (ED), it is worth the detour for its views, its apparatus and its overhangs. But beware, beginners should refrain!

Be careful, this is a very steep passage, it is almost like climbing for some sections. If the ground is wet, it is very slippery and dangerous.

Very difficult summit, 10% average for 12km from Le Bourget du lac, no respite. The view at the top is worth it and in high season there is a restaurant bar for refueling.
