Millau

official town tourism site -- apparently a town renowned for its leader gloves (how specific!), and more recently for the huge bridge that spans the gorge (see below). But it sticks out in my mind as the traffic jam on the way to a site alone worth travelling to France for: Aven Armand. 

It's as if the cave were a giant goldfish bowl in which you dropped a crystal growing kit. Boy do the French know how to put on a light show. Amazing presentation. Not at all claustrophobic. Be sure to walk by the hole on the surface. If your sheep started disappearing in there, you'd take a look too.

I scrolled through the 360* tour on the website, but it's hard to make out what you're seeing. Nothing on screen can do justice to the scale.

Also worth visiting since you're there: Montpellier-le-Vieux Take the cute little train through the site if you're not up to walking. Doesn't hold a candle to our Canadian Shield, but it's interesting that the French think it's "wild."

Not sure how the new bridge affects the paragliders we saw soaring up and down the valley, but it will sure ease congestion in the Tarn valley. Setting a world record for height, the masts are higher than the Eiffel Tower,  it's quite a source of pride to the French.
