Lake Khyargas, the one of the largest lake in Mongolia, is one of the top attraction in Western Mongolia. Another smaller Lake Khyargas, which contains saltwater, covers an area over 146.8 sq km, has a length of some 75 km, width is about 31 km and reaches a depth of about 40-50 m. The Lake fed by River Zavkhan gol and other smaller Rivers via Airag, nearly located smaller fresh-watered lake. The Lake and its surrounding area was proclaimed as National Park and established in 2000 and covers about 3,328 sq km. It also includes a freshwater lake Airag nuur. The basic attraction of the Lake is Khetsuu Khad (Hard Rock), an enormous rock sticking out of the water that attracts migratory cormorant birds. The birds arrive in April and hatch their young in large nests built on the rock. When the chicks hatch, their squawking is constant and deafening. The aura created by the white cliffs and shrill birds makes you feel as if you’ve arrived at the ocean. By October the cormorants are off again, migrating back to their breeding grounds in southern China.
