Impossibile! Exactly this applies to a visit of the cave of the same name. Discovered at the turn of the millennium while highway tunnel constructions, meanwhile, it is one of the biggest caves of the Trieste karst. And the term big can really be taken serious, particularly the volume of the galleries! Nowadays, the cave is entered via an artificial shaft, while the access within the highway tunnel is served for rescue operations. Some ladders and rope traverses later, a big balcony is reached before total blackness! 50 m below, the main gallery is reached with average dimensions of 80x130 m! Huge flowstone towers alternate with nice small forms in "smaller" niches! Conclusion: obviously impossibile and definitively one of the best caves in the whole area. Of course, the cave is closed.
