The hill towns are beautiful here, perched over the Luberon Valley. The narrow streets make for some interesting driving and enjoyable exploring. Here are a few images to give you a flavor of the countryside.
Roussillon has been a protected village since the 1940s, when further development was banned. One of the most photogenic villages, and the most colorful, the streets are crowded with people taking snapshots. It is famous for its quarry of ochre and red pigments used in paints around the world.
This is Bonnieux, less famous (and thus less touristy), but also beautiful. We spent a good long while in the cemetery at the top of the hill, enjoying the breeze, the quiet, and the view.
