A group in wetsuits took the plunge and went swimming in Lake Baikal's icy waters - the largest freshwater lake in the world.
During the colder months, the lake's surface freezes over, creating a stunning unique landscape of ice formations known as the "Sea of Ice Needles."
In a video by @egor_lesnoy, these brave swimmers navigate the icy waters. The group decided to picnic in the middle of the lake, using the ice as utensils.
This video was filmed on March 31.
