The Poulloguer valley in Coatascron is home to several mills, including the Poulloguer mill, which still has its wheel and water inlet, and the Brélantec mill a little further on. It has to be said that this valley was a place of intense activity, particularly linked to flax growing. Today, the meadows and pastures are gradually giving way to a different landscape: dry and wet meadows, undergrowth...
The route then heads towards Coatascorn, a typical little village, before returning to the Poulloguer pond.
