Driving directions from Chantilly to Campix: take D-44 to the west [and slightly north] from Chantilly . In about ten minutes one crosses the Oise river and enters the commune of Saint Leu d’Esserent, which is noticeable from a distance by its large abbey. The road direction signs to the campsite route you around the southern edge of town to the west, where you turn north on to D-12.
The route takes you just north of town. As you are about to leave the built-up area and come to large, open farm fields, you turn right [east] and wind around a very small [but with good directional markings to the camp] route to Camping Campix.
