Ruskeala is a mysterious and mountainous region located in the very heart of the Republic of Karelia. It is home to a majestic canyon edged by snow-white cliffs that once served as a marble quarry. Workers however stopped extracting this cold stone and nowadays the canyon is considered a natural site. This huge bowl, once carved out by human hands, is now half full of the purest subterranean emerald-toned waters. The old, abandoned quarry is now a destination for tourists with a scenic two-kilometre trail passing along the edge of the canyon. RTG TV host Igor Maximenko checked out this route to see what all of the hype was about.
