Around the three rivers (Ille-et-Vilaine, Loire-Atlantique)


The loop of the three rivers is a 137 kilometer hiking trail located in the departments of Ille-et-Vilaine and Loire-Atlantique, in France. It follows the courses of the Vilaine, Don and Isac rivers, and offers a variety of landscapes, from forests to marshes. The trail begins in Redon, a historic town located on the Vilaine River. It then follows the Vilaine towards the south, crossing forests, fields and villages. At Fégréac, the path leaves the Vilaine to follow the Don towards the north. The Don is a narrower river than the Vilaine, and the path crosses hillier landscapes. At Nozay, the path leaves the Don to follow the Isaac towards the east. The Isac is a smaller river than the Don, and the trail crosses wilder landscapes.
