Paris-Sud University can be reached either by
car or by RER (suburb train network).
RER B connects Orsay with both airports (Charles de Gaulle or Orly), and with
all parisian train stations, via the subway.
You can find a RER map here and a RER schedule here.
In RER stations, you will find two types of displays:
Prices indicated below were those of June 2007, they may have been
slightly modified by now.
- some give only the final destination of trains (take only
"Orsay" or "Saint Remy les Chevreuses") with their passage time.
Some give a list of all the stations: the small light in front
is "on" if the train stops in the station.
At the bottom, a light indicates if the train is "long" or "short".
If it is short, be careful to wait where other people are, if
you don't want to have to run after the train when it arrives.
A ticket from Paris to Bures-sur-Yvette costs 4.05 euros (a set of 10 tickets
costs 32.40 euros).
To come to the symposium, you should rather get off at the station "Bures sur Yvette"
(RER direction "saint remy les chevreuses") ,
though it is also possible to walk from "Orsay Ville"
(RER direction "saint remy les chevreuses" or "orsay").
- From airport Charles de Gaulle
- We advise you to take RER B (the ticket from CdG to Orsay costs 11.15 euros). Take any train from CdG to Paris (but if possible, it is better to take
a direct or semi-direct train, they are much much faster). Then you may have to change
in Paris: get off for example in "Luxembourg", stay on the same side
and wait for a train that goes to "Bures sur Yvette" (direction "saint remy
les chevreuses"), or to "Le Guichet" (direction "Orsay") if you want to reach "Hotel d'Orsay".
- The taxi from CdG to Orsay costs approximately 100 to 120 euros (in the evening).
- From airport Orly
- You have to change in "Antony" (OrlyVal to RER B)
- From Paris station "Gare du Nord"
- Direct connection via RER B
