How to reach us

 /  /  / How to reach us

Access from train stations and airports

IPhT is located 20km south-west of Paris, in a place called Orme des Merisiers (see map).

How to reach us by train and bus

  • RER B Le Guichet + Bus:
    From Paris or Charles-de-Gaulle airport (or Orly airport via Orlyval and Antony station), take the train RER B direction Saint-Remy-les-Chevreuse. The simplest and fastest is to take a train to Le Guichet (approx. 35 minutes from Paris, 1h15 from Charles-de-Gaulle, make sure your train stops there). Off at Le Guichet, take the pedestrian underpass at the front of the train. Turn right after the café and cross the street. A pedestrian way on the left leads to the bus station. Bus 9 (the default bus at this station) leaves every 5' at rush hours (and typically 20' throughout the day, except for a 30' gap between 11:15 and 11:45) and reaches Orme des Merisiers in 8'. This bus is free with a weekly or monthly pass "Navigo"; otherwise, tickets are 2 euros if purchased on the bus, 1.5 euro if you buy 10 at a time from the vending machine in the train station (carnet 10 tickets t+).
  • RER B Massy-Palaiseau + Bus:
    The second option is to take the train RER-B to Massy-Palaiseau (approx. 25 minutes from Paris, 1h05 from Charles-de-Gaulle) and take bus 91.06B, 91.06C or 91.10 which reach Orme des Merisiers in 20-25 minutes. This is not recommended on your first visit, as there are many bus stops, and indications are poor.
  • The optimal route (through Le Guichet or Massy-Palaiseau) depends on the time: check http://vianavigo.com/en/routes-district-maps/ (enter "Orme des Merisiers, Saint-Aubin" as "Arrival point"). If you are staying for a while, we recommend that you download the apps RATP (real-time information on trains) and Vianavigo (train and bus schedules, no real time information so far).
  • Entering the Site:
    Exit the bus at Orme des Merisiers. There is a gate for pedestrian access right in front of the bus stop. After the gate, go right. Once you reach the road, go left. IPhT is building 774 at the end of the road on the right side (approx. 10 minute walk from the bus stop).

How to reach us by walking from Bures sur Yvette (La Hacquinière) or Gif sur Yvette

You can reach IPhT directly by walking from the train stations of La Hacquinière or Gif-sur-Yvette on RER B. This requires both a valid access badge to Saclay and a good knowledge of the neighborhood. But the gate beside the swivel is generally open during the business hours.

It is not a valid option on your first visit. The walk includes a steep forest path uphill, which can be very muddy, thus take good shoes. It takes about 30 minutes for an experienced hiker to reach IPhT from La Hacquinière (see map).
