Located in the counties of Antu, Wusong and Changbai in southern Jilin Province, Changbaishan is one of China's nature preservation zones, covering an area of over 200,000 hectares, extending 78.5 kilometers north to south, and 53.3 kilometers west to east.The Crater Lake:It nestles on Baitoushan （The White-Head Mountain）, the main peak of the Changbaishan and is also a border lake between China and Korea. Surrounded by 16 exotic peaks, the lake is the crater of a volcano, filled with blue waters, known as The Heavenly Lake. The basin-shaped lake, 2155 meters above sea level, and 313 meters deep at maximum, encompasses an area of 9.2 square kilometers. It's a typical high mountain lake. The lake waters keep flowing out, without causing apparent change in its water level. The two white rivers of the upper reaches of the second Songhua River originate here. The inner side of the lake bank is craggy cliffs formed by rough-surface rocks and white pumice stones, which make the Lake resemble a marble bowl carved with uncanny workmanship. The surface of the Lake is smooth as a mirror, with the reflections of grotesque cliffs upon it in numerous exotic shapes.
