The world famous cave listed in World Nature Heritage since 2000 is situated nearby a coal mine village of Dobšiná in the National Nature Reserve Slovenský raj. Due to its character of glaciation, the cave belongs among the most important caves in the world. Ice fill is present in various forms and its thickness in some places exceeds 25 m. The best conditions for the formation of ice decorations are during the spring time when surface waters penetrate the crevices and start frosting, forming various shapes. At few places, a coat of frost is created due to the sublimation giving the underground spaces a special charm.
