French school holidays start on 8th July so the simple answer is yes it will be very busy. But it does depend on where you want to go. The coastal hot spots will be booked in terms of campsites and you will need to arrive very early at an Aire to stand any chance of a spot. Inland there are plenty of areas off the beaten track where you should be ok, it's a big country just bear in mind that the coast/rivers, e.g. Ardeche /Loire/Dordogne are the most popular.

Bastille Day fireworks at Annecy where fantastic when we where there several years ago but you need to be there the day before as parking anywhere is impossible
Thinking about a delayed trip to France now being July or even August.
Anecdotally everywhere is rammed full at that time. But is this true? Can you still find plenty of Aires and campsites at that time of year?
Thanks...
Thanks all, so far
I should have said we were thinking inland - burgundy, alps, that sort of thing.
