The Orda Cave revolutionized cave diving in Russia. It is a dream for divers compared to other sumps in the Russian Federation, and even in the world.
The cave system stretches over 3.2 miles, or 5.1km with around 3 miles or 4.8km over the overall length being under water.
This makes it one of the longest underwater caves and the largest underwater gypsum cave in the world. Orda cave contains the longest siphon in the former Soviet Union at 935 meters.
The gypsum crystal cave is found underneath the western Ural Mountains. The mouth is near the shore of the Kungur River just outside Orda.
The cave is the third largest gypsum caves in the world, but largest gypsum underwater cave in Russia and the world. In 2008, they were included in the UNESCO World Natural Heritage.
