Tonquédec castle is strategically located on its spur overlooking the Léguer valley, one of the most beautiful rivers in the Trégor region, which will guide your steps. You'll discover an abundance of flora and fauna. As you make your way upwards, you'll realise just how deep the valley is. Don't miss the short diversions through a coniferous wood leading to the Kerrivoalan fountain and chapel.
