Aktau Mountains in Altyn Emel in Kazakhstan

The Altyn-Emel State National Nature Park is a national park in Kazakhstan. It was created in 1996. The park covers about 4,600 km² between the Ili River and the Aqtau mountain range, near Lake Kapchagai, and consists mostly of desert and rocky terrain I visited the park fr the 4-th time in May 2026 ith my wife and 3 sons The Singing Barchan dune is 1.5 km (0.93 mi) long and 120 m (390 ft) high. The barchan is crescent-shaped. When the wind is blowing from the west dispersing the sands, it can sound as if a pipe organ is playing. The cause of this phenomenon is still a mystery, but scientists theorize that in hot dry weather the sand gets electrified due to friction and creates a certain sonic vibration
