Camping Car-Park Card for France

Used one last year , It was a good clean site with 6 amp electric and free wifi. It was very close to town centre so ideal .This one was €12.50 for 24 hours or you can just use the services for a small fee. There were a couple of places to stop a bit further out of the village but we opted for this.You have to join which can be done at the entry (instructions in English) and add money to the card or do it online before you go and add about €20 which would cover a stop ,and then try it out.

Yes we used it this year, bought card at Aire entrance €4 + Aire cost, I just paid at machine as I found topping up very difficult online, found them slightly expensive but clean except the one at Juno beach which we and a French van drove away from it was quite dirty

We've had the card for a few years and regularly use it. Camping-car Parks are now adding municipal campsites to the system and making them available to motorhomes all year. They also have a prebooking facility which means if you need to be at a site on a definite day(s) in high season you can reserve your place.

for that service

Tried to use Petit Port in Nantes very recently, topped up the card I've had for a few years now but only afterwards did it tell me that the parking was full.

Doubled back to the hyppodrome carpark very nearby which didn't appear to have any charges and had a sizable collection of vans.

A few dogs on ropes hanging around some vans that didn't look like they moved very far or very often was a little concerning but it was a short enough evening after docking in Cherbourg at 4:30pm.

Reality is that the dogs are security against all but their owners so its just a gamble that the owners won't sh*t on their own doorstep. Bit like motorhomists bring security to harbours even if some of the boatists don't like the look of them

There is an app too

Did you just turn up , normally if you check the location on the map/app they will tell you how many spaces there are and how many are free at that time. So you can book.
if you have joined their booking system € 24 per year,its as good as any of the other systems, the more you use per year the the better value .
