In reply to cpbarnes:
There is a very good one just to the south of St Paul de Fenouillet where the Agly goes through a gorge on the D 619, strait off the parking. About TD- I would have thought. Just by it is an easy one for kids and the elderly, but worthwhile and popular with organized parties. If you are in that area well worth visiting in the opposite direction from St P the Gorges de Galamus on D7/10
