The Cascade Du Flumen
The Cascade Du Flumen are in the Jura, on the French side. They can be accessed either with a 1.6km walk from a large parking nearby that requires going over a few pot holes or down a steep path with loose scree. What makes the waterfalls so spectacular is that they are formed not by water flowing over a cliff and falling to the ground. They are formed by holes in the rock allowing water that has been through underground caves to seep through the rocks.
