It was named after a protected Mediterranean plant – the butcher’s broom – a prickly evergreen Eurasian shrub (Ruscus aculeatus -- csodabogyó in Hungarian), which grows at the cave’s entrance, and whose habitat reaches its northern border here. The galleries of the cave were created by tectonic movements resulting in formations of corridors, halls and shafts. It has a multilevel structure with a cave network, and its fissures widen as they get deeper, acting as natural geological cross sections and demonstrating the upper limestone layers of the Ederics region that surrounds the cave, dating from the Triassic Age. The cave was explored in the 1990's, although a shorter section had already been discovered in the 1970's; however, it was only fully prepared for tourism and opening to visitors many years later. The currently known corridors extend over six kilometres, making it the eighth longest cave in Hungary, at a depth of 136 metres below ground.
