The Eisensteinhöhle is named after its original owner, Reichsritter Eissner von und zu Eisenstein. Its original name was too complicated to last: Reichsritter von und zu Eisenstein-Grotte. It was discovered during quarry works in 1855 and first explored by some officers from the K.K. army. The owner, above knight, immediately stoped all quarry works to protect the cave. In 1907 the cave was developed as a show cave by the Sektion Wiener Neustadt of the Österreichischer Alpenverein (Austrian Mountaineering Club). They still maintain the cave and the cave museum.

The cave is not really a show cave, the tours are rather rough, and it is open only two weekends per month. Thus a cave museum was built, to inform visitors at other times or those who are not able to visit the cave.

The tours are called "Höhlenabenteuer" (cave adventure), which gives the impression that they are cave trekking tours. This is not the case, it is more like a historic show cave tour, but the tour requires some physical fitness. The cave visitors are fitted out with helmet, overall, boots and carbide lamps. Old clothes are advisable. The tours goes down a shaft, over four iron ladders. At some points of the tour the ceiling gets low and it is necessary to crawl. Also, 75 m down and back up costs some energy. Visitors should think about their physical fitness before they visit this cave.

At the lowest point of the tour, a thermal spring with 15 °C is reached. This thermal spring influences the cave climate. The temperature is at least 5 °C higher than would be normal at this altitude. And this extraordinare cave climate is also resonsible for the amount of interesting calcite crystals which can be found all over the cave. Cave corals and aragonite crystals are very common. The high temperature is also responsible for a high number and variety of cave fauna, like Atheta spelea, Trechus austriacus and other cave insects.

The Höhlenmuseum Eisensteinhöhle (Cave Museum Eisensteinhöhle) is a small speleological museum, located at the entrance of the Eisensteinhöhle. The museum was primarly created as an information center for the cave. It contains maps, surveys, photographs, documents, and gear of the early cave explorers to document the history of the exploration. This exhibition is completed by an overview of the geology and the fauna and flora of the area.

The museum was created by Kulturabteilung des Amtes der NÖ Landesregierung, the culture section of the government of Niederösterreich.
