By Car

If coming by motorway :

  • From Paris, take the A10 (direction Bordeaux) then at Orléans Nord, the A71 (direction Bourges).
  • From Paris or Vierzon, on the A71, exit at junction 2 Orléans-Sud (direction Olivet / Orléans la Source)

After the toll barrier, follow the N271 towards Orléans la Source. At the interchange, take the left lane and drive over the N20. This takes you onto the Route de Bourges which runs through an industrial park into the Avenue du Président J.F. Kennedy. The University campus is on your left. Drive straight on over several traffic lights until reaching a T-junction in front of the Lycée Voltaire. Turn left into Rue Beaumarchais, then right at the mini-roundabout on the Avenue de la Recherche Scientifique, then left at the traffic light into the CNRS campus.

If coming by the N20 from Paris, there are two possible routes (see the map of Orléans) :


  • → Follow the N20 into the town center of Orléans and turn right at the train station
  • → Cross the Loire river by the Pont Joffre and drive straight on southwards along the N20 for 6-8 km.
  • → After passing the Zenith (on your left) and the hypermarket Auchan (on your right), take the second exit, signposted Orléans-La Source.
  • → This takes you onto route de Bourges (see above for further directions).


  • → Follow the N20 into the town center of Orléans and turn left at the train station
  • → Follow the signs to Orléans la Source which bring you onto the expressway avenue Gaston Galloux southbound over the Loire (Pont Thinat)
