Features: Locals say some visitors who came to the eastern shore of this lake gasp, “look at that huge white lake!” and so it was named Terkhiin Tsagaan Nuur (Huge white lake). A small island in the lake is inhabited by birds that build their nests and lay their eggs. Black geese and seagulls dive at depths of up to 5 meters to catch pike. In 2011, CNN named Terkhiin Tsagaan lake as one of the world’s best tourist destinations. The lake is surrounded by the Khangai mountain range and more than 10 rivers, including the Terkh, pour into the lake while Suman river flows out. Academics have proven that Khorgo was a volcano that erupted twice 9 million years ago and became dormant. Khorgo volcano, 2240 meters above sea level, is the youngest of all the volcanoes in the country. Its pre-historic lava flowed 100 km to the east of the mountain, and to the Suman and Chuluut rivers. The crater slopes at about 50 degrees, its depth is about 100 meters, and its diameter is 300-400 meters. Inside the crater you may see large stones, the size of tables and chairs. Between the trapped stones of the Khorgo mountain, small cedar trees are growing with plenty of cedar nuts and berries. There are caves too. Three dormant volcanoes Bosgo, Khyar, and Suga are located 20 km from the Khorgo mountain. The Bosgo crater has a crack on its northwest side, and has a lake at its bottom. A rare type of diamond was found near a clay mountain in the area of Khorgo.
