It is located on the Duča Plateau in the Slovak Paradise National Park. It reaches the length of 22,027 m together with interconnected Psie diery Cave. It is formed in the Mesozoic Middle Triassic Steinalm and Wetterstein limestones of the Stratená Nappe.
The Stratenská Cave stands out mainly by mighty underground spaces, when the Rozprávkový Dome with volume over 79,017 m3 is the largest cave space in Slovakia. The calcite speleothems are in forms of straw and bigger stalactites and curtains, but mainly as mound, cone, pagoda and stick stalagmites. Cascade and other lake formations, rare cave pearls in the shape of hemisphere (hemispheroids), aragonite crystalline protrusions, eccentric dripstones and gypsum are also present. The largest lake is Stalagmitové Lake with an area of 320 m2.
Fourteen bat species have been recorded by now. Dominating are the Greater Mouse-Eared Bat (Myotis myotis) and the Lesser Horseshoe Bat (Rhinolophus hipposideros). The troglobitic springtails Arrhopalites aggtelekiensis, Deuteraphorura kratochvili and Protaphorura janosik are representatives of the invertebrates. A new species of mite Foveacheles troglodyta, which is endemic species of the Slovak Paradise was discovered here. Blind cave crustacean Niphargus tatrensis lives in underground waters.
The cave is also an important palaeontological locality. The richest finding place of cave bear (Ursus spelaeus) bones in Slovakia is in the Psie diery Cave. The bones findings are 15,490 to 17,530 years old according to geochronological dating.
The Stratenská Cave was discovered by V. Košel and J. Volek in 1972. The Psie diery Cave was connected in 1994. The long-time speleological survey and research is done by cavers from Spišská Nová Ves.
Due to low yield of underground water the boat trip in Domica Cave is not available. The short tour is available. Thank you for understanding
