Podziemna Trasa Turystyczna w Kielcach, Cave system in Kielce, Poland.
The Podziemna Trasa Turystyczna is a cave system in a former quarry composed of three connected caverns that extend roughly 400 meters. The network displays limestone formations, red earth layers, and rock fissures highlighted by carefully placed lighting.
The caves were discovered during limestone quarrying in the 1960s before the site was abandoned. The route later opened to tourists, making the underground geology of the region accessible to the public.
The cave displays fossils from an ancient sea, including corals and shellfish, presented through light and sound installations. Visitors can see these petrified remains from the Devonian period directly as they walk through the underground network.
Visitors should book in advance since tours are limited and conducted with safety helmets provided. The route takes about 45 minutes and temperatures remain consistently cool year-round, so warm clothing is recommended.
The cave floors are colored with terra rossa, a red earth layer created by iron compounds. This rare formation shows how mineralized soils develop underground and gives the underground space its distinctive appearance.
