The Vorontsovskaya Cave (Воронцовская пещера) was the first cave to be surveyed. It may be accessed through a dozen entrances dotting the slopes of the Kudepsta River valley, at heights ranging from 419 to 720 meters above sea level. The Prometheus Grotto, with a length of over 120 meters, is developed as a tourist destination. The cave takes its name from the nearest settlement, Vorontsovka. It is known to contain bones of cave bears and early humans.[1]
In the late 20th century, it was discovered that the Vorontsovskaya Cave is connected to the Labyrinth Cave, the Kabany Proval, and the Dolgaya Cave by a network of sumps, or siphons. Some cave chambers lie 240 meters higher than the others. This cave system has been mapped to about 12 kilometers.[2] It is ranked as the longest in Krasnodar Krai and the 6th longest in the Russian Federation.[3]
