Travel to Orsay
From the airport
LAL 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 (35 minutes from Châtelet, 4,20 Euros for a single ticket and 1 hour from Charles de Gaulle).
From Charles de Gaulle airport
RER station is located at "Roissypole", linked by CDGVAL light rail.:
From Terminal 1: The RER station is not located inside Terminal 1.
Take the CDGVAL light rail (5 minutes journey) to "Terminal 3-Roissypole".
CDGVAL station for Terminal 1 is located at level 2;
From Terminal 2: RER station is underneath Terminal 2, between Terminal 2C/2E and 2D/2F.
Go to the rail station by walk (look for "Paris by train" or "Gare" signs) or board free shuttle bus ;
From Terminal 3: The RER station is not located inside Terminal 3.
Look for "Paris by train" signs (follow the signposted footpaths).
RER station is 400 meters away from the terminal (5 minutes journey by walk) .
From Orly airport
Take the Orlyval (Automatic rail link connecting to RER line B) to the Antony station and then transfer to the RER B going to Saint-Rémy-lès-Chevreuse (and not to Robinson) and get off at Orsay-Ville. Buy a ticket at Antony for Orsay. The price is 11,45€.
Please do not mistake the RER B station "Orsay-Ville" for the Paris metro station "Musée d'Orsay". From Paris, you must buy a ticket specifically for "Orsay-Ville". A Paris metro ticket is not sufficient !.
By road from Paris :
If you leave Paris from "Porte d'Italie" or "Porte d'Orléans", take the A6 autoroute in the direction of Lyon ; on the autoroute, after 10 km, follow in the direction of "Bordeaux" ; after another 10km, take the Orsay exit and follow panels to reach Orsay and "Faculté d'Orsay". After this, look up in a local map to find LAL.
If you leave Paris from "Pont de Sèvres", take the N118 in the direction of "Bordeaux", after 30 km, exit at Orsay. Then, follow "Faculté d'Orsay" or find the RER-B train station "Orsay-Ville". After this, look up in a local map to find LAL.
In principle, going to Orsay from Paris in the morning is "against the flow" : "pros" do the trip in 30 mn ! (Speed is limited to 110 km/h on autoroute, 90 km/h on national roads, 50 km/h in town).
From the station "Orsay ville"
Exit station and to the left take the pedestrian tunnel that crosses back under the railway (follow the students) go down "Rue E. Desjobert", following the "Orsay University" arrow. At the bottom of the hill, turn left "Rue de Launay" and go straight following the road that crosses the Orsay campus. The main LAL entrance (building 200) is on the left, around 10 minutes walk from railway station.
