Underwater Universe of the Orda Cave

A documentary team from Japan sets out to explore the Orda Cave, a series of cave systems filled with crystal clear water underneath Russia’s Ural Mountains.

The cave’s waters are clearest in winter, when the land above lies frozen.

Today, the Orda Cave has shown to be one of the longest underwater caves in the world and has emerged as one of the best cave dives in the world.

To film the Underwater Universe of the Orda Cave in all its splendour, our documentary crew brings their best gear to shoot the film in ultra-high definition 4K for the first time ever.

The crystal clear waters inside the Orda Cave have some of the most pristine visibility of any underwater cave on the planet of up to 150 feet (50 m).

Along the exploration of the cave, we’ll attain insights from experts regarding the cave’s origins.

This enables the Japanese film crew to uncover the miraculous story of how the cave was naturally formed. It is a 300 million years story, one which shaped the cave by terrain shifts and climate changes.
