Lighting by which to see the natural colours of the crystal formations that decorate the cave, together with a tour led by trained interpreter-guides, enable visitors to appreciate the delicacy and richness of the stalactite- and stalagmite-shaped calcium deposits.
Your tour, lasting 40 minutes, will take you through different galleries and chambers, in some of which small pools of water collect. You will recognize the chambers from their names: Romantic Chamber, Lake Chamber, Enchanted Castle, Palm Tree Chamber, Musical Waterfall, etc.
The cavern is a series of chambers, and the total distance overed underground is a little over 400 metres. The passages and chambers have been eroded out of Upper Triassic (Rhaetian) dolomites.
They are entered by a short artificial tunnel leading to a downward-sloping vestibule, called the Palm Tree Chamber, where the main galleries of the cavern start from.
As you head north-westwards, a few passages with relatively low ceilings lead to the Lake Room characterized by the presence of a gour, which occupies a low area amongst paving flowstones and abundant stalagmites. The pathway leads right around this chamber and back to the vestibule. From there, heading north-eastwards, you come to the most voluminous room in the cave: the Romantic Chamber, measuring 50 metres at its widest point, and up to ten metres high in places.
