Rock, valleys and caves
The Vorontsovskaya cave was formed in limestone laid down 120 million years ago. It is the longest karst chamber in Krasnodar Region at 11 700 metres. The Vorontsovskii cave system is made up of three parts: Vorontsovskaya, Labirintovaya and Kabanaya connected by sumps, which are narrow passages filled with water. In any weather the air temperature in the cave is 10–120С.
