Baradla is a show cave, part of the Domica-Baradla cave system (included in the UNESCO World Heritage List since 1995 as "Caves of Aggtelek Karst and Slovak Karst") developing across the Slovakian and Hungarian border.

The cave has separate entrances at Aggtelek and Jósvafő; it is formed in the Middle Triassic (Ladinian) lagoon limestones of Wetterstein type.

Guano deposits are present as small accumulations from individual bats, or as large guano heaps. Among phosphates spheniscidite is found in a white laminated layer near the bottom of a guano accumulation, close to the contact with limestone and clay substratum; it is associated with taranakite, quartz, and illite. Hydroxylapatite occurs with calcite in the "urine crust" covering ceiling cupolas; fluorapatite in a yellow layer associated with brushite and quartz.
