The upper reach of the Katun River flows down the distant and sparsely populated area, but a few kilometers downstream near the Kujus village, the coastal population density grows steadily and the area downstream of the Ust-Sema village is the most populated. There are numerous buildings, holiday camps and various guest houses in the pine forest near the village.
