Beausejour is the only site you can turn up at without a ticket.
Bleu Nord is the old Bleu bivouac site, which expanded as people turned up. The ACO cottoned on to the idea of selling it in advance. It's been sold out for ages.
If you want a Bleu pass I have a spare. PM me for details - you'll have to pick it up on arrival.
Thanks for the advice..
I ended up buying a Houx Annexe camp ticket from a member here..
This campsite is un-numbered, right?
Hoping this will reduce my walking distance for the weekend
Kpy; I think you are mistaken somehow.. i have been in blue nord for the last 5-6 years.. and allways just turned up friday, and bought the camp-ticket at the gates.. no way it is sold out before saturday..
