(S/E) The route starts from the hamlet of Chames, which you walk through; here, a small stony path begins, running past a mobile phone mast.
On a rocky path, you’ll look out over the Tiourre stream and the ruins of the old mill.
(1) At the first Fork in the road, continue left through a pine forest until you reach the Tiourre spring.
(2) At the spring, you reach a Fork in the road and take the path on the right, which begins to descend alongside the stream.
During the descent, you can see numerous natural pools formed by the limestone-rich waters. After heavy rain, you can see many small waterfalls.
(3) You finally reach the ruins of the mill, which is now little more than a field of rubble, though it still features a magnificent reservoir filled (or not, depending on the season) with intensely turquoise-blue water, worthy of a mountain lake.
We continue our descent to rejoin the path we took on the way up, via a short, rather slippery climb.
Avoid following the red and white markings, which zigzag and make the route longer.
(1) Carry on to the left until you reach the hamlet of Chames (S/E).
