Sacred space, Saint-Just was frequented by Neolithic people for several millennia. Our distant ancestors settled on these dry moors to form a major complex of megalithic monuments, the second most important in Brittany, after Carnac. On a route of about 6km you can discover various alignments bearing strange names often linked to a local legend. The path can be walked, run or even cycled across a moor that offers no shade or shelter. A magical and fascinating place in every respect

At La Chapelle-de-Brain in the Pays de Redon, the natural area of the Gannedel marshes promises a pleasant walk between reedbeds, wet meadows and bodies of water. A circuit fitted out with footbridges and observatories facilitates the exploration of the site of great ecological value.
