Introduction to the Yalu River Grand Canyon: The Yalu River Grand Canyon is located at the southern foot of Changbai Mountain. It is the only way to reach Tianchi Lake. The canyon is 10 kilometers long from north to south, 200 meters wide from east to west, and 170 meters deep. It is also the source of the Yalu River from Tianchi Lake. The valley is shaded by green trees, and there are many strange rocks and peaks on both sides of the valley. It is of various shapes and grandeur, which can be compared with the famous Jinjiang Grand Canyon in the south and north of Changbai Mountain. At the Gutou River where the Chinese and Korean rivers meet, the towering Huya Peak is the representative of the canyon landscape.
