CAMECA from downtown Paris

There are numerous possibilities to get to our head office from Paris by public transportation...

The easiest: RER C line

You may take it at any RER C station: Saint Michel-Notre Dame, Musée d'Orsay, Pereire... (Should you come from Metro line 1, get off at "Porte Maillot" and take the connection to the RER line C at "Neuilly-Porte de Maillot".)
Make sure you are taking the right direction by checking the destination boards. Destinations appear on the boards just before the trains enter the station. To get to CAMECA, the correct direction is Pontoise or Montigny-Beauchamp (train names NORA, GATA, or GUTA ).
Get off at Les Grésillons RER C station (15min travel).
Walk 10min to CAMECA: exiting the station cross the street (Avenue des Grésillons). Turn left onto Av. des Grésillons and turn right onto Rue Olympe de Gouges. When you reach the busy road along the Seine river ("Quai Aulagnier" which will transform into "Quai des Grésillons"), turn left and walk 300m to CAMECA. Walk by the AMETEK flag and take the main entrance near the CAMECA flag.
Note regarding RER C: the RER C line breaks into different directions at a certain stations. To avoid surprises, check train names carefully before boarding: in order to reach Les Grésillons station, you need to board either a GATA, GUTA, or a NORA train.
