The Ordinskaya Caves, Orda for short, are world famous for their incredible visibility and unforgettable scenery. Orda is the world's largest underwater gypsum cave and the longest underwater cave in Russia. Orda is located near the Ural mountain range and is reachable by couple of hours car ride from the nearest airports.
The first expeditions to Orda were done in 1994. In 2006 a mapping project was begun. But even today, there are unchartered areas with question marks on the map. Cave line covered by huge boulders acts as a reminder that this is a living cave.
