Gorges Mystérieuses

verified Ungraded Unknown flood risk

Short canyon between Chamonix and Martigny. Do not go in there in Summer, there is a huge water capture that can open anytime (also in Autumn, but once it gets cold the risks are not as high anymore).

A deep gorge, but also wide, with some nice rappels in the water, including a short obscuro underneith some huge boulders (no need for headlamp though). Not many escapes, maybe it is possible the touristic path just before reaching the boulders.
