There is also apparently lots of ‘wild camping’ opportunities up in the Massif des Maures (hills) up behind Saint Tropez- if you don’t mind being remote and with few other campers and facilities, this is a great way to keep costs down.
There are some good places to park motorhomes that we’ve personally seen along the Riviera coast. There’s a brilliant one by the water at famous Pampelonne Beach by Saint Tropez, for 10 euros a night, and there are always motorhomes parked along the beach at Antibes (Plage de Salis) and along the beach and near the train station in Biot. Beachfront parking is not always allowed overnight, but there are motorhomes there pretty much year round so we can only suspect that the French parking inspectors will sometimes turn a blind eye. The Aires guide will have this information so you don’t get caught out.
Biot and Antibes are good choices (particularly Biot) as these towns are on the train line, meaning you can park up and take the train to Nice and Monaco in one direction and Cannes in the other. There are also official campsites at Biot- 'La Brague' and 'Camping du Pylon'.
Nice: There isn’t any overnight parking within the city, but there is an Aire at nearby St Laurent du Var (just by the airport), as well as official campsites at Cagnes sur Mer and Villeneuve Loubet Plage (not the village as it’s miles away). These coastal campsites and aires are all great for train travel into Nice or Monaco.
Menton: In the other direction towards the Italian border, Menton is an absolutely gorgeous seaside town of villas and exotic gardens, where it’s rumoured that you can park your motorhome in the parking by the port. You can then catch the train or a bus back into Monaco or any of the stunning cliff-lined beaches along the way. Again, check the Aires guide to be sure if the Menton carpark is ok.
In Provence, there’s an aire at St Croix overlooking the beautiful lake, and the one at Fontaines des Vaucluse in Provence also comes recommended.
