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.

This superb chapel located near Lake Guerlédan is dedicated to Sainte-Tréphine. Fairly recent, it was built between March 1897 and May 1898 on the initiative of Father Ollichon, rector of the parish of Saint-Aignan from 1892 to 1899. Its location in the forest adds to the ambient mysticism.

A very nice climb before enjoying this grandiose panorama in clear weather, but the effort is definitely worth it.
