Leave the square of Notre Dame de Paris Cathedral towards Saint-Michel quay, and then take the Rue Danton. Follow the Veloscenic signs until Montparnasse Tower and place de Catalogne (roundabout). The rue Vercingétorix marks the start of « la coulée verte » a greenway leading you straight to Massy with no cars! An easy way to go out of Paris…
When you arrive in Massy, the Veloscenic split up in two ways:
Versailles way: 5 km from Massy to Jouy-en-Josas are not signposted yet. Signs should be installed by April 2017.
Limours way: 50 km of temporary route (no signs). We advise to download the roadbooks and gps tracks to guide you.
