Peshchera Katnikova, Protected limestone cave in Olenyi Ruchyi Natural Park, Russia
Peshchera Katnikova is a limestone cave in the Olenyi Ruchyi Natural Park along the Serga River in Russia, stretching approximately 357 meters. The cave system has a single entrance on the riverbank and internal chambers featuring stalactites and other mineral deposits.
A local resident named Katnikov discovered the cave in the 1930s, followed by formal documentation from teacher Raisa Borisovna Rubel in 1958. This early exploration established the foundation for its present status as a protected natural area.
The name comes from a local resident who discovered the cave in the region. Visitors can observe the distinctive limestone formations that define its interior today.
The cave maintains a constant temperature of 4.5 to 5 degrees Celsius year-round, so visitors should bring warm clothing. Sturdy footwear is important since the ground is uneven and damp inside.
The cave serves as a habitat for several bat species, including brown long-eared and Brandt's bats, which rest in its chambers during the day. This makes the site important for local wildlife conservation efforts.
