Grotta di Collepardo is also called Grotte dei Bambocci (Cave of the Children), because of the characteristic shape of its dripstones. It is well known for a very long time, because of its enormous size. The cave is visited since the 19th century, and the modern speleology of the 20th century was not able to find additional parts.

The limestone around Collepardo is heavy karstified. There are numerous sink holes, the ruins of caves with collapsed roof, with high and steep walls and flat bottom. Typical examples are Pozzo Santullo, Fossa della Volpe, and Fossa di Monte Capezzoi.

Grotta di Collepardo consits of two enormous chambers, divided by a wall of limestone formations. The cave is entered from the valley through a rather low portal. After a short passage the path lead up into a huge hall with numerous phantastic pilars and stalagmites. The path, constructed mostly as a iron bridge, leads the visitor through this huge cavern in a sort of 8. At one point a steep stair, cut out of flowstone leads to a side passage, but this historic track is not used any more. The tour is self guided, so the visitor has enough time to have a close look wherever he likes. All in all a very pleasant visit, with just one drawback: the light is extremely yellow, and so the whole cave gets a sort of sick look.

An impressive description of the cave was written by Ferdinand Gregorovius, who visited the cave in 1858. The original German text is linked below. He describes a cave visit, how people from the village used torches and burned fires to light the enormous cavern. The smoke of this fires painted the whole chamber black with tar.

He also tells the story of a french hermit who lived in a nearby cave, until he was jailed. The story goes, that he was connected with the assassination of Louis Philipp, and sent back to France.
