The Hanging Stone (Russian: Висячий камень, romanized: Visyachyi Kamen') is a 500-ton granite rock in Ergaki Nature Park, seemingly hanging 1,000 m (3,300 ft) above Lake Raduzhnoye.

The area features a chain of rocks or a ridge that appears to be a silhouette of a man lying on his back, which is said to represent a person from the legend known as "Sleeping Sayan".

[2] Local legend states that when the stone falls into Lake Raduzhnoye, the Sleeping Sayan will wake up.

[4] Several groups of tourists have tried to dislodge the landmark by pushing it down the mountain, but without any success.

The Ergaki Nature Park charges 4,800 rubles for a guided tour to visit the stone.
