Millau and Fontainbeau

Aquila

We are currently at Colle sur Loup on the Cote d'Azur but have to head north on Saturday for Calais by 12th April.

We are making a slight detour to see (cross?) the Millau bridge. I have looked at Camping des Deux Rivieres at Millau. Does anybody recommend this site or maybe another ACSI site nearby?

Also aiming to go via Fontainbleau for a spot of woodpecker watching and have looked at les Courtilles du Lido at Veneux les Sablons. Again does anybody have any thoughts?

Also ned a site near Calais and have seen recommendations before but cannot remember the site name.
