The full name of the lake is the Blue Lake of Black Heart. Black Heart is the pointed topped mountain on the north side of the lake. Blue Lake is a very important place in Mongolian history particularly of Chinggis Khaan (Genghis Khan). Here Temuujin (Chinggis Khaan’s childhood name) was given the title, “Chinggis Khaan”, and was invested as a “The Great Khaan of all Mongolia” in 1189. The stone ruins of a ger with a diameter of 15 meters on the south side of this lake could be the ruins of the palace ger where Chinggis Khaan was proclaimed khaan. There are also wooden statues in the forest dedicated to Chingis Khaan and the next 32 khaans of Mongolia. The surrounding area of Khukh Nuur is quiet, peaceful and wonderful for hiking & relaxation.
