Lyon
A huge city. A pretty city. A city I enjoyed for the first second I came to visit it. I went there twice, once without my camera, and the second with my camera.
In order to understand, to "feel" Lyon, you need to go all over it walking. Wait for a nice, sunny and windy day. Take good shoes, you're about to walk for almost 20 kilometers. Climb the leading-to-unknowness stairs, cross the various bridges... But take your time !
