Located north of Trestrignel, the Pointe du Château overlooks the town of Perros-Guirec to the east and the bay of the same name to the west. Picnic tables are available, ideal for a lunch break.
Previously at the base of an ancient tumulus, these megaliths discovered in Penvénan were for a time placed in Tréguier before being repatriated to their original commune, next to the Saint Gonval chapel.
