The length of the branched passages of the cave reaches 520 meters, the depth is 30 meters. The cave has high arches. Includes 15 grottoes, including the grottoes of Bats, Nizhny, Glybovy, Blind, Bolshoy, Chudes, White, Stalactite, Southern, Ozerny, Karst, Lyubitelsky, Maltseva, Gorge of Sounds. The largest grotto is called the Big one. Its length reaches 90 meters, width — from 1.5 to 5–6 meters. The height of the grotto is from 5 to 13 meters. A stream flows in the cave, falling like a waterfall into an underground lake. Its flow rate is from 12 to 20 l/min. The stream flows along the main course, then in the Ozerny grotto it falls from a height of 12 meters into the lake. This waterfall is the main uniqueness of the Pashiyskaya cave. On top are two organ pipes. The wet rocks here are very slippery. You need to be extremely careful not to slip down or get injured. There’s a chain here, just in case. The underground lake has a depth of 7 meters and a diameter of 15 meters. The water level in the lake corresponds to the water level in the Vizhay River. The water temperature is always constant (+4°C).
