Lie and Stand Cave is located in Ulziit Soum, Dundgovi Province. This cave is 2km away from Tsagaan Suvarga which is called Mongolian Grand Canyon. As for now this is the biggest cave, which was made by erosion and deposition in Mongolia. A lot of researchers are interested in this cave due to flowing water with clay mud forming the cave. Professor Avirmed has claimed its capacity is 102m long, 204 square meters, one of the biggest caves in Mongolia.

Travelers, who are visiting the Tsagaan Suvarga, mostly see this cave. This cave has 2 mouths. If you go into the north mouth you have to lie to crawl, then go into the big hall where you can stand and walk. There are a lot of bats in the cave.
