Vallée des Traouiëros walks

Along with the pink granite chaos, the Vallée des Traouïéro is the region's second most popular tourist site. It consists of two steep-sided valleys through which the Kérougant river winds its way before separating and joining the natural harbour of Ploumanac'h. This stream forms the natural boundary between the municipalities of Perros-Guirec and Trégastel. The Petit-Traouïero flows into the Ploumanac'h ice mill (Milin Ru), while the Grand-Traouïero flows into the Trégastel wheat mill (Milin Glaz).
