Introduction to the Kumukul Desert: The Kumukul Desert is more than 4,000 meters above sea level and is the highest desert in the world. From the foot of the huge sand mountain, clear springs gush out, presenting a wonderful scene of connected sand and lakes, coexistence of sand and springs, and alternating deserts and swamps. The sand spring in the sand mountain is very similar to the Crescent Moon Spring in Dunhuang. The spring water gushes out to form a sand river.
