Several discovery options for the Canche Gorges, depending on physical condition and available time:
One can, for example, park at La Verrerie (D978; Canche Inn parking) and hike up to the EDF power station then to the gorges.
If one hikes all the way, one reaches the dam parking lot on D179. The return to the starting parking lot can be done via the gorges or by road (D179 then D978; this will total approximately 9 km).
If one is an experienced hiker, choose one of the longer circuits passing through Canche Gorges.
