Travel to IJCLab Orsay

How to reach IJCLab

By public transport from Paris to Orsay

IJCLab is located on the Université d’Orsay Paris-Sud Campus, 25 kilometers south-west of Paris. The easiest way to reach the Orsay campus is by taking the RER B line to the Orsay-Ville station (direction St-Rémy-les-Chevreuses)

  • 35 minutes and direct from Châtelet, 2.55 € for a single ticket
  • 45 mins and direct from Gare du Nord/Gare de l'Est, 2.55 € for a single ticket
  • 1 hour from CDG airport (Terminal 1 or 3), 45 mins from Orly airport, 14€ for a single ticket

How to buy a ticket

To get a ticket, you can buy it on your cell phone on the app IDF Mobilités. Or you can purchase a navigo Easy card (2 €) at any train station : we do not recommend this as  national train stations/airports can be crowded with travelers buying a card.  For more informations : https://www.iledefrance-mobilites.fr/en/titres-et-tarifs/supports/passe-navigo-easy

If you plan on using the metro/bus system extensively in Ile de France, a Navigo week pass (zone 1 to 5) can be interesting as it includes Orsay, airports, and Paris unlimited for 32.4€ (but only from Monday to Sunday).
