The Grotte des Planches, in the heart of the Jura's highest box canyon,
is home to France's primary active underground river. The Cuisance has
been shaping the cave for thousands of years, to offer visitors an
extraordinary spectacle. Stalactites, organ pipes and pine forests...
just a few of the geological features that puzzle the greatest experts.
Not forgetting the many giant pot-holes scattered around the cave,
forming the finest collection of its kind in Europe. |
