Paradise Cave was first discovered in 1963/64. It is under protection as a natural reserve because of rich travertine formations, scientific and didactical virtues. It also a protected archaeological post. Making the cave accessible helped protecting its unique formations and moreover – enabled scientific researches. The cave opened for tourists in 1972.
In 1963 Józef Kopec and Feliks Wawrzenczak came across a cleft running deep into the rock while excavating limestone on the slope of mountain Malik. Soon after some teenagers from neighbouring village Sitkówka got through it destroying some of dripstones. The cleft discoverers covered its entrance with rocks to prevent possible accidents.
In 1964 once more the cave was entered - this time by students of Cracow Geological College (Bohdan Baldun, Zbigniew Bochajewski, Wlodzimierz Lucki and Wojciech Pucek). During summer training they had a chance to enter and see beautiful sights that charmed them so much that they called the place “paradise”. The day after students came back with instructor – Mrs. Miroslawa Boczarowa. After that the entrance was covered for some time and fact of cave’s existence was kept in secret.
