The awesome stature of the 'Millau Suspension Bridge' is just a 1:1/2 to 2 hr drive from here and you really won't regret the effort. It is an amazing feat of engineering and is the largest of it's type in the world!
Drive up to it, under it, over it and around it, take a light lunch in the pretty town of Millau beneath the bridge and drive home via 'Roquefort' where you can visit the caves and shops or do a tour and some tasting of this fine cheese.
You can buy certain cheeses here that are not available anywhere else in the world.
This is a highly recommended day out.
