In the heart of the Côtes d'Armor, near Locarn, the Corong Gorges offer a spectacular landscape. Crossed by the Follezou river, we discover a huge pile of rocks shrouded in legend. An almost magical place! Source: https://www.tourismebretagne.com/destinations/les-10-destinations/coeur-de-bretagne-kalon-breizh/les-gorges-du-corong/

Nice walk of about 5 km. Not difficult, but unsuitable for people with limited mobility. This because of a crossing over large boulders that are not made.
