[3] The Primorsky Range stretches northeastwards for about 350 kilometres (220 mi) along the western shore of Lake Baikal from its southern end.

It is located in the area of the sources of the Lena and to the north it connects with the Baikal Range, which also stretches along the lakeshore.

Its eastern side is made mostly of rocky cliffs descending steeply to the shores of Lake Baikal, opposite Olkhon Island.

[5][6][3] The Primorsky Range acts as a watershed between the rivers of the Lake Baikal and the Angara/Lena basins.

Short and fast-flowing rivers have their sources in the range, including the Anga, Bolshaya Buguldeyka, Sarma and Goloustnaya, which flow into Lake Baikal.
