Ryadovaya cave was for many years considered the shortest cave among all caves of Aya bay. After cleaning of narrow passages, inside the cave a lot of branchings were found, as well as a well of about 10 meters in diameter and 20 meters deep. Later this cave was connected by speleologists with Aya cave. This way it was transformed into the longest cave at Baikal shore. The length of all passages is 1000 m.
