Get onto the SIA website
SIA : Service d'information aéronautique. Contrôle et réglementation de la circulation aérienne. and buy the 2014 folder 'Documents VFR' About 35€ and worth every penny:
Includes two handy 1:1.000.000 charts covering the whole of France and booklets listing frequencies over the whole country.
Also valuable stuff about low level military routes: everything you could wish to know.
In French and English.
Indispensable IMHO.
