Guide officiel Aires de services camping-car 2023: Toutes les aires repérées sur un atlas routier Paperback – Illustrated, 2 Feb. 2023

Have used this guide for the last 25 ish years. Make sure you go for the latest one on Amazon 2023, there are lot of older ones for sale so be warned.

Had I known, I'd not have bought it.

A slim paperback containing a huge amount of useful information. All in French so I photographed the "key" pages and used the Translate function on my iPhone, then Screenshot the translation, printed it and kept it with the guidebook! As we made no campsite bookings, it proved useful in identifying several excellent places for overnight stops.
