s of 2018[ [update]], there are 843 caves known in the Polish Tatra Mountains with the total length exceeding 134 km. They are within Tatra National Park. All the prominent ones are limestone karst caves of the Western Tatras, but there are also some tectonic caves. The largest and deepest caves of the Tatras (and of Poland) are located in the Czerwone Wierchy and Kominiarski Wierch massifs. Another highly promising region, the massif of Giewont, is largely unexplored due to its strict nature conservation status.
