Our second last day in France saw us seeing several amazing landscapes both caused by erosion. One took a few thousand years and the other a few million.
Orgues Ille sur Tet has some weird and wonderful shapes caused by wind and rain eroding the soft sandstone which is still a work in progress.
The other stop was Gorges de la Fou a narrow gorge (reputed to be the narrowest in the world) around 2 kilometers long and up to 250 meters deep. The walk through the gorge is made possible by metal walkways with netting overhead to catch falling stones. Even though some sections are only a meter wide we spotted some Trout living in a few of the pools between waterfalls.
