Grotta della Bigonda, Cave system in Valsugana, Trentino, Italy
The Grotta della Bigonda extends over 30 kilometers through three distinct levels of dolomite rock formations, reaching depths between -108 and +350 meters.
Local researchers discovered the cave entrance on March 28, 1952, during aqueduct work, leading to initial explorations by the Tridentine Alpinists of Trento.
The cave system represents a significant element of Trentino's natural heritage, containing geological formations that demonstrate the region's complex underground network.
Access starts from Ospedaletto at 458 meters altitude, with guided visits limited to winter months when rainfall decreases and water levels permit entry.
The cave houses 18 distinct animal species in its ecosystem, including organisms that exist exclusively within this subterranean environment.
