By bike

  • From RER B station Le Guichet, with the bakery to your left, take rue de Versailles.
  • Then, you may take the second street on your left, "rue de la colline". When you reach the cross roads, take a right on Chemin du bois des Rames and go left at the next stop sign.

This is the most direct route, however, it is very steep going up and has no bike lane.

  • A gentler option is to keep on rue de Versailles until the top of the hill. When you reach the second round about, take a left.
  • Go straight at the traffic light, and at next round about. Then take a right at the stop sign. LIMSI will be on your left at the next stop sign.
