An exciting excursion to discover the fascinating underground world! We will go up an underground stream, among rooms rich in concretions dating back to millions of years ago. Stalactites and stalagmites, sometimes joined in incredible columns of calcium carbonate whose date of origin is difficult to imagine, will make the visit a real experience. We will use wetsuits to easily pass under waterfalls and if we want we can dive into a crystal clear underground lake.
If we wish, it will be possible to try a short stretch of bottlenecks and then visit the room of silence where we will experience absolute darkness. At the end of the excursion there will be also the opportunity to visit the characteristic village of Fornovolasco, set at the foot of the Apuan Alps.
