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.

The ascent is worth it: fantastic panorama and also an opportunity for a short rest with the opportunity to sit in a sociable group with the Lunerus😊 (it is somewhat reminiscent of "Number 5").

The beautiful and varied hiking trail to the summit cross alone is a pleasure, and once you reach the summit, you have a breathtaking panorama in all directions (Alps, Lac du Bourget, Chamberry, Aix-les-Bains, mountains and valleys). Highly recommended 😀👍!
