This is really a must do in the Aravis - if you feel safe in exposed trails. To be avoided at the very beginning of the summer though, as there is pack of snow on steep slope in the Combe de Pacaly. .

Hiking

After a nice climb, we find ourselves straddling two very different valleys under this natural limestone arch, all in all impressive.

Hiking

We were there at the end of September 2024, and there was already a lot of snow. Be sure to check the weather conditions beforehand. The snow made the hike significantly more challenging. Many people weren't well prepared.
