Cascade de la Pisserotte

The cascade drops in a straight vertical line down a limestone cliff, creating a single unbroken column of water that stands out against the rock face. The waterfall sits within steep hillsides covered in forest, with the white ribbon of water visible from several points along the approach path.

The waterfall was carved by the Grand Moulin river over thousands of years as it cut through the limestone formations of the Chartreuse range. The present shape reflects ongoing erosion from mountain water flow and seasonal variations in water volume.

The area around the waterfall reflects the region's long connection to mountain farming and small-scale food production. Visitors walking through the area notice how cheese-making traditions shape daily life in the valley settlements.

The waterfall is reached by a marked hiking trail starting from the Les Grollets hamlet, with a walk of about 10 minutes to reach the main viewpoint. Sturdy footwear is advised because the path can be slippery and steep, especially when water levels are high.

After the main drop, the water collects in natural basins along the riverbed, creating small pools with clear water. Visitors often miss these secondary pools when focusing on the main waterfall, yet they offer their own quiet beauty away from the falling cascade.
