You can also see in the photo the train tracks which wind through the mountains, quite amazing - including some impressive feats of engineering, like this bridge.
Apart from the natural beauty, some of the highlights included wandering through the UNESCO town of Villefranche , and the citadel of Mont Louis. Mont Louis was really interesting, because the main fort is still used by the military as a Commando Training Centre - they have filled the moat with obstacles, and have ladders up the walls, looked like a big adventure playground!
Also at Mont Louis is the excellent Four Solaire. It used to be a CNRS research project, but it is now used to power a kiln. The temperature at the focal point of the light get up to 3000C, and even on a slightly cloudy day we saw smaller demonstration versions melting bricks and setting fire to wood. Here is a video of Andy doing that.
