AIRVŪZ STAFF NOTE :
Lake Baikal is buried in the mountainous region of Siberia, Russia, north of the Monglian border. It’s considered the deepest lake in the world at 5,387 feet, is ancient and absolutely massive at over 12,000 square miles. Popular in the summertime for wildlife-spotting tours, it is also used in winter by cars, dog sled teams, and other curious travelers who don’t mind Siberia’s harsh cold.
