Nature reserve Jaskinia Niedźwiedzia, Nature reserve in Kletno, Poland.
Jaskinia Niedźwiedzia is a nature reserve in Lower Silesia featuring an underground network of limestone caves with multiple interconnected chambers. The site offers several routes of varying difficulty, from standard passages to more challenging sections for experienced explorers.
The cave was scientifically explored in the 19th century and later designated as a protected area to preserve its underground formations. This designation was part of a broader Polish conservation movement that developed over the following decades.
The name comes from bear bones discovered here thousands of years ago, marking an important chapter in the site's past. Visitors today walk through vast chambers that speak to ancient human and animal presence.
Plan your visit in advance since entry is available through guided tours offered on a regular schedule. Wear sturdy shoes and bring a warm layer, as underground temperatures remain cool throughout the year.
Excavations at this site uncovered prehistoric bones of cave bears, which inspired the location's name and sparked ongoing scientific study. These discoveries provide researchers with insights into how animals and humans inhabited this region during the Ice Age.
