FATMAP difficulty grade
This is not a hike for the faint-hearted.
Inaugurated in 1994 as an official way-marked walk, the path is unique in that it commemorates one of the several secret escape routes over the central Pyrenees into northern Spain during the Second World War.
A route taken not only by hundreds of Frenchmen and Jews fleeing from their German oppressors, but also by many R.A.F.
and American airmen who had either crash-landed or parachuted to safety after being shot down over Nazi-occupied Europe.
