In reply to Tiny stone:
Yeah, last Easter was a great opportunity to visit quiet areas I'd never been to, we were staying at Musardiere and couldn't find parking at any of the major areas at all.
What surprised me was how ridiculously obvious it all was, I have had to fill gaps where the campsites weren't available in the past by sleeping in the van for a couple of night, but it was always out of the way, inconspicuous, and leaving nothing behind, when we saw massive campers with their awnings out all the way to the road and toilet paper all over the place in all major areas last year we knew we probably wouldn't be allowed to do that again in future, at least nowhere near the forest.
