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.

At this former station there are many different train sets in very different conditions. We also saw carriages from the Montblanc tramway. Tram rides are offered.
