Baikal Ice Diving — Siberia Russia
Lake Baikal's winter ice — up to 1.2 metres thick from January through April — creates the world's most extraordinary freshwater diving environment: water of absolute clarity (visible to 40 metres), the world's deepest lake at 1,642 metres, and an endemic fauna (including the world's only freshwater seal, the nerpa, and 1,700 endemic species) that has evolved in complete isolation for 25 million years. The diving requires drysuits, hotwater equipment, and the cutting of a 1-metre hole through 1.2 metres of ice, but the reward — descending through the hole into water of absolute blue clarity, the ice surface overhead letting filtered winter light through, and the Baikal epischura (tiny endemic shrimp that produce the water's legendary clarity by filtering it completely every few years) visible as motes in the beam — is one of freshwater diving's most profound experiences. The nerpa seal's curiosity-driven investigation of divers produces encounters at 1-metre range.
About this spectacle
Descend through a metre-wide hole cut through 1.2 metres of ice into water so clear that visibility extends 40 metres in every direction. Above you the ice ceiling glows with filtered winter blue-white light; below, darkness dissolves into the world's deepest freshwater column at 1,642 metres. The Baikal epischura — tiny endemic shrimp — drift as luminous motes in your torch beam, their ceaseless filtering responsible for the lake's legendary transparency. Nerpa seals, the world's only freshwater seal, approach divers with unsettling curiosity, hovering at arm's length before spiralling away into the blue. The drysuit insulates against near-freezing water while the ice surface overhead creates an otherworldly cathedral of refracted light. This is an environment that has evolved in isolation for 25 million years, with 1,700 endemic species sharing the water column around you. Morning dives catch the best light through the ice, turning the overhead canopy into a luminous mosaic.
