The Alba Regia cave is the third deepest cave in the country. Its exploration was begun in 1975 and due to the hostile environment it took for quite a long time. In October, the entrance test hole, which depth is almost five meters, was dug. Exploratories went along the next 30 metres through strait routes full of scree. Then, beyond some crannies, they reached the so-called "Explorer branch" of the cave in which the first stalagmites could be seen. At the bottom of the test hole, sunk in extremely difficult circumstances, the channel was opened on 24 October. The air temperature of the inner passages of Cave Alba Regia is about 7 degrees lower than the Hungarian average 8,1-8,5°C. During the exploration, the strong enrichment of carbon dioxide in some passages became apparent. It is Istvan Eszterhas who collects and converses the wildlife of the cave that was wholly closed until its discovery. He started trapping in 1976, and even in that year he could differentiate between 21 species. In 1977, the number of cave creatures increased to 56, and in 1979, it was as high as 70. The cave can be visited only with a permission and a professional guide.
