Jaskinia Mroźna is called Frosty Cave or Ice Cave as it is rather cold because of its altitude. As a result there are only few speleothems. The cave is entered through an artificial tunnel and left through a natural entrance, the tour is a through trip. The cave has a single, more or less horizontal passage.

The Koscieliska Brook appears in the cave and at one point forms the Sabalowe Jeziorko (Sabala Lake). The biggest chamber is the Wielkiej Komory (Great Chamber), 27 m long, 10 m high.

The Kościeliska Valley in the Tatra Mountains is a popular hiking area. The valley has four caves which are open to visitors, three of them are semi-wild caves, and Mroźna is the only show cave with trails and electric light. The only way to reach this cave is by walking through the vally and then taking the trail which leads up to the cave. It is located in the eastern slope of the Kościeliska Valley in the Organ massif, 120 m above the valley floor.

From September 2020 to April 2021 the cave was closed for a massive renovation. It included the construction of a 12 m long wooden shelter at the exit, because there is frequent rockfall from the cliff face above. Also nets were used to cover the rock face to protect the trail from falling rocks. The ticket office at the entrance, a wooden hut, was renovated and got a new roof. Also the trails inside were renovated and equipped with stainless steel railings. Nevertheless you should not expect a comfortable show cave, its more like an underground mountain walk, with stooping, crawling, and even a litte mud and water for crawling through.

From the sounds of the people in front it was an interesting and surprising experience for them too. It was brilliant, and completely different to an English show cave!
