Those Romans were an industrious lot

Pont-du-Gard (week 7)

The Nîmes aqueduct was a major feat of engineering, moving water 50 km with a drop in elevation of only 17 m.  It had to cross the river Gardon, hence the Pont (Bridge) du Gard (Gardon).  It is the second-tallest remaining Roman structure, after the Colleseum in Rome.

The site is well designed.  It charges each car €18 to enter and anyone in the car is admitted to the site; it's a good deal considering foot traffic is charged €10 a head.  The site contains a neat museum, several small shops, excellent sanitary facilities, a kids play area (we didn't go in), all for the carpark price.  It was unusually muggy the day we went, although the sun stayed mostly behind clouds.  So hiking around the site was warm, especially since there is a lot of up-and-down if you want to get out to the places with panoramic views.

We ended up at the bottom, where you can swim in the river (or rent a canoe or kayak to paddle under the bridge).  It was a good place to cool off at the end of the tour.
