The 36-kilometre long Carquefou - Saint-Mars-la-Jaille Greenway, follows the former railway line between Carquefou and Saint-Mars-la-Jaille. Turned into a path for cyclists, pedestrians and horse riders, it is a great way to discover the countryside around Carquefou. Road crossings are signposted and equipped with barriers.
