The 700-year-old willow in the Kosbastau oasis is a unique natural monument of Altyn-Emel. Rising 20 meters high with a trunk girth of 15 meters, it provides cool shade beside a small lake and a radon spring, offering relief from the desert heat. Legends claim Genghis Khan once rested here, though the tree likely sprouted later. Sacred to locals, the willow is a peaceful and refreshing stop for travelers en route to the Katutau and Aktau mountains
