Pontrieux is a small Breton town on the tidal River Trieux, known for its remarkable collection of private washhouses — over fifty lavoirs tucked along the riverbanks, many of them beautifully restored and open to visitors during guided boat trips in summer. It is a quiet, picturesque place with half-timbered houses reflected in the river, and a good stop on a tour of the Côtes-d'Armor.
The town comes alive on Thursday mornings for its market. From Pontrieux you can take a river cruise downstream through wooded banks towards the coast, or head north to explore the Pink Granite Coast around Perros-Guirec.
