The first written mention of Baradla cave dates back to 1549 and from 1920 it serves as a tourist attraction.

Ján Majko discovered Domica Cave (Slovak part of the complex) in 1926 and the tourist circuit opened to public in 1932 has more than 1,700 metres (5,600 ft).

The cave is also experimentally used for "speleotherapy" as a sanatorium, focused on airway diseases thanks to constant temperature of 9 °C (48 °F), high humidity of 98% and favorable microclimate.

Dobšiná Ice Cave was added to the list of components of this World Heritage Site only in the year 2000.
