Very beautiful circuit through the countryside between Morbihan and Loire-Atlantique, passing through Briandais and the Château de la Roche Hervé.

Built in the 14th century and rebuilt in the 19th century, the Château de la Bretesche stands out for its privileged location on the water's edge. Seeing it suddenly appear as you cycle along the D2 is a splendid sight.

I really didn't understand how to get to the dolmen. The path that was supposed to go there was blocked off. I was able to take a photo over the hedge of the field next door, but it was still very disappointing.
