• Do not confuse RER B station "Orsay Ville" with Paris subway station "Musee d'Orsay".
• From Paris, take explicitly a ticket for "Orsay Ville". A Paris subway ticket is not sufficent !.
• There is a special ticket called "Carte hebdomadaire" that permits to have a special rate for a "Paris Orsay-Ville" and a "Orsay-Ville Paris" per day for six days. Ask for a "Carte hebdomadaire Paris Orsay-Ville". The price (July 2000) should be 144 FF. Note that "Paris" includes also an entry in the subway.

If exiting Paris from "Porte d'Italie" or "Porte d'Orleans", take the A6 highway, direction Lyon ; on the highway, after 10km, take the direction of Bordeaux ; after 10km and after the exit Massy-Palaiseau, take the exit Orsay. But you are not directly in the center of Orsay. Follow panels to reach the center of Orsay, then follow the panels "faculte d'Orsay" or find the RER-B train station "Orsay-Ville". After look the upper local map to find LAL.

If exiting Paris from "Pont de Sevres", take the direction Bordeaux, after 30 km, exit at Orsay. You arrive directly at Orsay, then follow "faculte d'Orsay" or find the RER-B train station "Orsay-Ville". After look the upper local map to find LAL.

In principle, going to Orsay from Paris the morning is "against the flow" : "pros" do the trip in 30 mn ! (Speed is limited to 130 km/h on highways, 90 km/h on roads, 50 km/h in town).
