Thanks for that. That looks perfect if we can get on early next week.
Under "Open/Closed", there is a comment that it is permanently closed, buildings having sprung up since.
For daytime at least, you might consider parking at the Bordeaux Lac retail park and using the nearby tram line. Not sure what the position would be re parking there overnight.Both if possible, but daytime essential.
Streetview April 2019 shows a sign indicating that motorhomes are permitted in the Allées de Chartres car park between 0800 and 2000.Allees de Chartres seems to be quite a central car park used by Motorhomes. Some staying overnight. Last time we were in Bordeaux was several years ago when we stayed at village du lac campsite. It was an ACSI site at the time, but had a bus service from the door. There did seem to be a more basic ability to park just inside their gates. Don’t know if it was an overflow or private Aire.
