Cascade de la Lauze is a small waterfall upstream form the big Cascade de Nerech south of Les Bordes sur Lez in the French Pyrenees.
From Saint Girons drive west over road d618 until you reach Audressein, here you take the d4 to Les Bordes sur Lez and further on to Vallee du Riberot(Reserve de Domaniale du Mont Valier). There is a sign, turn left here. Drive on until you reach a big parking.
From the parking at Maison du Valier it is a 5 kilometer walk (80-90 minutes) over a trail (GRT55) following the river Le Ribérot south. Just before a steep part of the trail you first see the great cascade de Nerech. After the climb you finally reach the Cascade de la Lauze.
