On its rocky peak, the castle of Foix and its imposing stature, dominate the medieval town. With a strategic position at the confluence of the Arget and Ariège rivers, the Ariège castle had a strategic role: to control access to the Haute Ariège valley, to monitor the low country and to protect the counts behind its high impregnable walls. It is the symbol of the power of a fiercely independent county engaged in the defense of the Cathar cause. Resisting many assaults, the castle of Foix was never conquered. During the Catholic Church's crusade against Cathar heresy, the counts of Foix, souls of the Occitan resistance, welcomed and protected the persecuted by refusing to submit to the authority of the King of France. It is the cradle of the famous counts of Foix: Gaston Fébus (1331-1391) and Henry III, King of Navarre, future King of France Henry IV.

A magnificent spot with the road winding under the rock, running alongside a partially underground stream. It's both breathtaking and peaceful. Plus, there's a starting point for a short walk; I did the beginning and it was lovely: I'd love to come back and do a longer section!

Don't trust the no trespassing sign. Private property! Danger of death prohibited! We almost missed it because of those two signs! You have to be careful, yes, like everywhere! But to put danger of death 🙄! Plus, there's a lifeline where there would be danger! But honestly, we didn't see any danger! Done with an 8-year-old, no problem!
