Chapelle de la trinité (Castennec) walks

A circular loop along the meander of the Blavet, passing by the Saint-Gildas Chapel overlooked by a rock. Beautiful view of the Blavet, on the site of Castennec in the commune of Bieuzy. A few short steep sections on the way back, but no major difficulties.

This very pretty route revolves around the Blavet valley, starting from Saint-Nicolas des Eaux, and allows you to discover some very interesting natural sites (the banks of the Blavet, Lande du Crano) as well as some remarkable examples of Breton architectural heritage (the semi-troglodytic chapel of Saint-Gildas, the noble houses of Bieuzy, the chapel of Saint-Nicodème, the locks). This walk is fairly well signposted (yellowPR® markings).
