The offer
Frequently asked questions
How intense is the Ecot Canyon descent?
The physical level is rated 'occasionally sporty', meaning you'll push yourself during specific sections like rappels and jumps, but the overall experience is accessible without prior canyoning training. Expect bursts of adrenaline rather than sustained physical exhaustion.
How cold is the water in the Ecot Canyon?
Bonneval-sur-Arc sits at high altitude in the Haute Maurienne, so canyon water is fed by glacial and snowmelt streams. Water temperatures are cold even in summer, particularly earlier in the season. A wetsuit is provided by the operator.
What is the scariest moment of the descent?
Rappels down granite walls are typically the most intense moments in alpine canyoning. The Ecot Canyon features technical rope sections where you control your own descent over rock faces with the guide's support.
Is the season really limited to May through September?
Yes. High-altitude canyons in the Alps like the Ecot depend on stable water levels and safe conditions, which only align between May and September. Outside that window, snowmelt and ice make the canyon unsuitable for guided descents.
