Lake Kuvsgul, cradled in the forested mountains of northern Mongolia, is known locally as Mongolia’s dark blue pearl. The lake is surrounded by several peaks near 3000m high, and to the west, there is the Darkhadyn Khotgor depression with plentiful forests and lakes. Mongolia's largest fresh water lake Khovsgol  is 125 km long and plunges to over 260 m and contains 1% of the world’s fresh water. In this region, around Tsagaan Nuur, live the fascinating Tsaatan whose lives revolve around the domesticated reindeer.  Its geological origins, flora and fauna are similar to those of its neighbor, Lake Baikal. Over 100 rivers and streams flow into the lake, but only one river flows out. There is an abundance of rare wildlife in and around the lake including several fish species and big horn sheep, called Argali. The Khuvsgul area is home to diverse ethnic groups including the Khalkhas, Buriats and the Tsaatan reindeer people who migrate between Khuvsgul and Buryatia each year.
