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.

Caution: Be careful when descending; the descent can be perilous due to the slope; you can quickly get carried away by the speed. Beware of the speed and crosswind combination with high-profile wheels 😱🫣
