Lake Baikal is still the pride of Russia and the deepest as well as the cleanest lake on the planet. It contains about 19% of the world's fresh water. The purity of Lake Baikal creates an incredible world. Especially in winter, when the lake is suddenly covered with ice crust. Bubbles of methane and oxygen from plants quickly freeze, creating an incredible atmosphere. Cracks, bumps, spray in the grottoes on the shore - all this is so unique and beautiful that it is breathtaking.
