This circuit was designed and painted by Loïc Blondeau, Guillaume Dieu and Elie Dupont between 2022 and 2024. It consists of 36 problems and 4 bis problems. In addition, there are numerous connections. This is a 'mountain' circuit, meaning we invite you to complete it in one go, without a crash-pad, in comfortable climbing shoes or approach shoes, depending on your comfort level. The climbing/down-climbing/traversing sections will allow you to follow a logical sequence with little or no return to the ground. A small twist: some problems are underground passages; sometimes a headlamp can be useful!
Finally, each boulder is named after a mushroom. For those who know about mushrooms, the name of the mushroom will give you a little clue, such as the problem's beauty or its exposure.
