Trzy Kopce Cave

Trzy Kopce Cave, also known as Klimczok Grotto, lies on the southern slope of Trzy Kopce in the Silesian Beskids, within the Brenna municipality. It is a natural monument and one of the longer underground systems in Poland’s flysch Carpathians: surveyed passages extend for about 1,244 metres, with a 32.6-metre elevation difference.

What makes it special

The cave formed in Godula sandstone as a landslide and fissure system. Its maze runs on several levels between large rock blocks; the entrance is a rectangular shaft about 4.3 metres deep. Inside are larger chambers and narrow fissure passages. It is an interesting geological feature of the Beskids, not a conventional show cave with a lit visitor route.

Safety first

The cave is not operated as a regular tourist attraction. Official descriptions highlight difficult access, damp and tight sections and the need for caving experience. In winter, the underground passages shelter hibernating bats, which must not be disturbed. Do not enter without suitable equipment, a competent partner and the necessary skills; the entrance shaft itself requires care.

Seeing the site responsibly

For most visitors, the best option is to treat the cave as a geological point along a mountain hike. The approach uses the yellow trail from the Klimczok area towards Błatnia, followed by a forest section from Trzy Kopce to the southern slope. Check trail conditions, weather and local conservation rules. The marked, fenced entrance can be viewed from outside without turning the site into an improvised underground tour.
