About
South of Saint-Paul-de-Fenouillet, the Agly river has carved the clue de la fou. The best way to explore the walls of the clue is the via ferrata which offers a magnificent panorama on the syncline and a view plunging on the gorges below.
An old bridge spans the river. Below are the "marmites de géants".
