Ordinskaya Cave is located on the left bank of the Kungur river, the Perm Region. It’s the longest underwater cave in Russia and the second longest underwater cave in Eurasia.
The cave consists of a “dry” and an underwater part. The length of its underwater passages is more than 4,600 m while its dry part is 300 m long.
Its transparency is deceptive though. Once you make an abrupt movement with your fins, visibility will drop to zero.
This is where you can breathe in some air.
