From the West (Pont de Sèvres) take the motorway N118 direction Bordeaux (about 14 km) and exit direction Saclay to immediately reach the roundabout Le Christ de Saclay.
From the South (Porte d'Orléans or Porte d'Italie) take the motorway A6 (about 10 km), switch to the A10 direction Palaiseau (about 7 km). Exit by the left lane, direction Centre Universitaire-Saclay to take the D36 until the roundabout Le Christ de Saclay (about 7 km).
Once you reach the roundabout Le Christ de Saclay, take the N306 direction Gif-sur-Yvette until you see a golf course on your right, after the main section of the CEA's Research Centre. Just after the golf course, there is a cross-roads: turn left, direction CEA Orme des Merisiers by D128. The entrance is 150 m further on the right.
