The greenway is an old railway line repurposed for walking, cycling and rollerblading, located in the Loire-Atlantique and Ille-et-Vilaine areas. Motor vehicles and horses are not allowed. You will see forests, ponds, fields, longères (traditional local farmhouses) and small bridges. If you wish, you can travel along it for around fifty kilometres. You will find many paths for hiking in Pays de Châteaubriant (300 km of marked trails) and can explore unspoilt landscapes and a wealth of heritage features like ovens, crosses, wells and manors.
