Mt St Michel-Rennes-Nantes
The Breton Amis de St Jacques have developed a route linking Mt St Michel via Rennes with the main Breton route between Redon and Nantes (300km to Clisson). A guide, Le Chemin du Mont-Saint-Michel : Vers Saint-Jacques-de-Compostelle, guide pratique du pèlerin, published by Rando Edns (ISBN 2841822605), describes the route on to the Tours route at St-Jean-d'Angély.
