In the Kazakh history of mountaineering and tourism there are a number of «torn pages». The fact is that the «white spots «in the history of mountaineering and tourism in Kazakhstan, in our opinion, due to the fact that in Soviet times there was almost no detailed research on the historical past of tourism and mountaineering in Kazakhstan. The date of birth of alpine sports in Kazakhstan is 1930, so the historical countdown of the achievements of Kazakhstan mountaineering was made mainly from this period. However, modern researchers have found a lot of unique materials about the first mountaineering practices in Kazakhstan, both in the pre-revolutionary period and in the 20s of the twentieth century. It should be noted that there are a number of interesting publications of A.G. Lukhtanov about the first mountaineering and mountaineers in Kazakhstan at the end of the XIX century. And as for the 20-30s of the last century, the information about the enthusiasts who rushed to the mountain passes and peaks of the Northern Tien Shan, is quite stingy and almost in different sources just repeat each other. Moreover, the personality, as well as merits in the development of the mountaineering of one of them, who can rightly be called the first mountain tourist and climber of Soviet Kazakhstan - Grigory Ivanovich Beloglazov, did not receive proper appreciation. Therefore, the purpose of this publication is the author’s attempt to show who was the first among the Kazakh mountaineers in the 20-30s of the Soviet period on the basis of the collected materials, which are published for the first time.
