Mylna Cave

Mylna Cave is a horizontal limestone karst cave located on the western slope of the Raptawicka Turnia massif, in the Kościeliska Valley of the Tatra Mountains, southern Poland, at an elevation of approximately 1,090 to 1,098 meters above sea level. The cave extends roughly 1,630 meters in total length and consists of a network of narrow passages and chambers formed by the erosion of limestone through underground water flow. It has three main entrances, with around 300 meters accessible via a marked route.
First explored and named in 1885 by Jan Gwalbert Pawlikowski. The caves underwent explorations in the mid-20th century that discovered entrances and corridors. The caves were interconnected to form an underground system within Tatra [National Park, Poland|Tatra National Park].
