Located not far from the village of Fontane, the Bossea Cave begins with a narrow and winding gallery that, after about a hundred meters, suddenly opens into a vast environment characterized by the roar of an underground river. A long series of steps gradually ascends to even larger areas where the dripping water has formed stalactites, stalagmites, and columns.
The limestone formations reach their maximum dimensions in a colossal hall, measuring 150 meters long, at least 50 meters high, and 60 meters wide. Here, visitors can admire on the left a gigantic stalagmite over ten meters tall, which has tilted at a 45° angle due to a floor collapse (known as The Missile), a stalagmitic tower that resembles a hill (Torrione Sella), and on the right, an imposing mammillary flow at least 25 meters high (referred to as The Buddha).
The path continues to a beautiful waterfall that cascades down into the lush green of the Ernestina Lake, accessible via an airy walkway from a canyon. On the return trip, visitors pass near the top of Torrione Sella, then descend along a very scenic trail that, taking a different route from the outward journey, offers new underground landscapes. The hydrology and meteorology of the cave are monitored by a modern scientific station.
