Coming from north (Paris), it is not possible to turn left to our airfield, because the highway is separated by a wall.

You have to continue driving on the highway just to the next drive / gateway (Torfou / Mauchamp) and than making a half turn. Now you are driving in direction to Paris.

If you are passing a gas station (sign: "Bas de Torfou") continue driving about 100 meters, turn right into a little street and take this street to the end. You have arrived your destination.

Welcome to the airfield of the M.C.B.
