Traouïero Valley
Perros-Guirec / Trégastel
About
Exploring the magical countryside of the Traouïero Valley is one part of the trail not to be missed. A small stream runs through this deep, wooded valley, which is flecked with blocks of pink granite shaped by erosion over 300 million years. Thanks to its unusual microclimate, many rare and endangered species of ferns and mosses flourish here. Intense granite extraction activity also developed in this area. Isidore Etienne, from the Vosges, set up this area's first large quarry in 1925. Many Italian workers crossed the Alps to help mine this exceptional material. To help you explore this unique landscape, you can pick up the special leaflet available in the Tourist Offices or join a guided tour leaving from the Trégastel tidal mill.
