A great detour to Saint Aignan, the Les Pêcheries de Guerlédan restaurant is very welcoming, with bike parking, a generous meal and welcome. Crossing the village, you can reach the canal a little further on via the lock.

A stretch on the dam before the Trehu Moron dam. The landscape is constantly changing. The canal meanders through the countryside here. I love this landscape, and it's a good mood to drive here.
