October 5, 2024,sur le circuit des 25 bosses au départ du parking du Cailleau : randonnée technique et exigeante

500 m difference in altitude but only rock
Recommendations:
- no poles needed
- only do it in dry weather
- good physical condition
- bring water and supplies
- red markings to follow but a map and/or a GPS app is a significant plus
And above all, have fun 😉
