Access to Institut d’Optique Graduate School at Palaiseau

By public transportation
  • Go to Massy-Palaiseau, a major public transportation node 15km South-West of the city center, mainly accessible through the RER B and RER C rapid transit lines, both of which are within easy reach from anywhere in the city of Paris, including all long distance train stations.

Direct RER B trains are available from Roissy Charles de Gaulle airport (from Orly airport, use local transit train ORLYVAL to reach RER B at station ANTONY).

Note that a few TGV trains call at Masy-Palaiseau TGV, a 2 min walk from Massy-Palaiseau RER B.

  • From Massy-Palaiseau, use bus lines 91-06B, 91-06C or 91-10 (bus stop alongside the RER B track, see attached map) to station “Ecole Polytechnique (D128)”. The bus stop is in front of Institut d’Optique. Busses run frequently week days 7:00-19:00. (Hickers may use station “Lozère” rather than Massy-Palaiseau and go for a 25 minutes uphill walk).

Note : special fares apply to all RER rides outside the city of Paris. Purchase a ticket to Massy-Palaiseau. On bus 91-06B, 91-06C and 91-10, use a “t+” urban metro ticket or purchase a ticket from the driver.
