Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is the oldest (25 million years) and deepest (1,700 m) lake in the world. Although it's not the biggest lake in the world in size - that distinction goes to the salty Caspian Sea - it is the largest by volume.
Nicknamed the Pearl of Siberia, Lake Baikal holds about 20% of the world's fresh surface water - more water than all of the North American Great Lakes combined. Known as the 'Galapagos of Russia', its age and isolation have produced one of the world's richest and most unusual freshwater faunas.
