Located in southern Siberia in Russia, Lake Baikal is the world's largest freshwater lake, accounting for about 20% of all-year-round unfrozen freshwater on the earth's surface.

In terms of freshwater, it is more than all five lakes of the Five Great Lakes combined. In terms of surface area, Baikal is the 7th largest in the world.

This is the deepest and oldest freshwater lake in the world, with a date of 25-30 million years.


With a depth of up to 1,642 m, Lake Baikal is also the deepest lake in the world and is the oldest when it formed about 25-30 million years ago.

East of the lake is inhabited by the Buryat tribe. People live by grazing goats, cows, camels, and sheep. This is also where there is a harsh habitat when the average temperature in winter is about -19 degrees Celsius and summer is about 14 degrees Celsius.

The surreal beauty of Lake Baikal in winter.

In winter, the lake water is very clear. Even in open areas, the transparency of the lake is visible to a depth of 30-40 m.

It is also the time when the thick layer of water froze on the surface of the lake, with an average thickness of 0.5 m to 1.4 m. In some places, the ice is up to 2 m long. This thickness can withstand a vehicle's payload of about 15 tons. So winter is the time when the stream of tourists from all over flocks to the lake for ice skating and viewing very crowdedly.

The fissures of the ice can extend to tens of kilometers, thus preventing the fish living below from suffocating due to lack of oxygen.

On the surface of the lake, sometimes the ice is slippery and reflective like a mirror. In addition to scenic walks, sometimes visitors wear skates or sled to experience all kinds of different feelings.

The thick ice surface can even withstand a 15-ton truck load.
Tourists walk on frozen lake.

In particular, many sections on the lake bed appear white cracks with strange shapes. These cracks are 2-3m across, and up to 10-30km long.

Also thanks to the cracks, many fish species deep in the lake bed do not suffocate due to lack of oxygen. Until now, the ice in Lake Baikal still carries many mysteries, attracting the attention of scientists.

The world of flora and fauna around the lake is very rich, some of which are not found elsewhere.

Currently, Lake Baikal is home to more than 1700 species of flora and fauna, up to two-thirds of which are not found in other places such as Baikal seals, zibelin weasels, Siberian mink, Siberian musk deer, Lemming mice ... UNESCO recognized Lake Baikal as a World Heritage Site in 1996.
