Hmm, it's not the one I'd pick. I cycled through Rocroi a couple of years ago, it's much more impressive from the air than it is on the ground - you're mainly looking at earthworks, and can't really see the plan. I passed through Verdun the next day, it's similarly disappointing - you can't see it until you're close by, then it's just a wall. Vauban fortifications with the advantage of high ground are far more photogenic on foot, eg Belfort and Briançon.
