Here the origin of the path can be seen: it was an old railway. The old station is well maintained.

A pretty iron bridge, built for farmers at the time. Here the path along the water was in a bad state in April 2026 (a warning was installed on one side of the section, but a detour through the forest is possible).

The reconstruction is great! But we left some parts in ruins, which preserves the character of an old building.

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.
