Cascade de Cau or Cascade Cau is one of the many waterfalls in the river Ruisseau Hourradade not far from the famous Cascade d’Enfer in Vallee de Lys/Bagneres de Luchon in the Pyrenees, France.
From Bagnere de Luchon drive south on the D46 into Vallee du Lys and cascade d’Enfer. At the end of the road there is a parking but it can be very crowded. The walk to cascade d’Enfer is a popular daytrip for tourists and for hiking in the valley.
From the parking follow the signs to cascade d’Enfer, but almost directly at the left side the river Ruisseau Hourradade cascades down the mountain. The first waterfall you will see is cascade du Coeur. Early in the season a very nice waterfall and very photogenic. The second waterfall upstream is the smaller Cascade de Cau.
Unfortunately I can’t find any reliable information how Cascade de Cau looks like.
Upstream you will find at least 4 other great waterfall, but the hike will take time and you have to ascend over 500 meters over a steep trail
