Lake Manasarovar is frequented by pilgrims almost as often as Mt. Kailash

  Lake Manasarovar is frequented by pilgrims almost as often as Mt.  Kailash, and it is associated with many myths and religions.  The limpid blue to emerald green colors of the lake, in contrast to the arid landscape immediately around it and the silver mountains beyond, help to make the lake a highly praised destination for pilgrims.  Lake Manasarovar is at an altitude of 14,950 feet above sea level, and is noted as the highest body of fresh water in the world. 

  Manasarovar is the most venerated of all Tibets many sacred lakes. It is especially sacred to Hindus, who have been walking round it for approaching 2,000 years. Buddhists associate the lake with Maya, Buddhas mother.
  Lake Mansarovar is a place of pilgrimage, attracting religious people from India, Tibet and the neighboring countries. Bathing in the Manasa Sarovar and drinking its water is believed to cleanse all sins. Pilgrimage tours are organized regularly, especially from India, the most famous of which is the Kailash Mansarovar Yatra which takes place every year. Pilgrims come to take ceremonial baths in the cleansing waters of the lake.
  According to Hindu religion, the lake was first created in the mind of the Lord Brahma. Hence, in Sanskrit it is called "Manas sarovara", which is a combination of the words manas (mind) and sarovara (lake). The lake, in Hindu mythology, is also supposed to be the summer abode of swans. Considered as sacred birds, the swans (Sanskrit: Hamsa) are an important element in the symbology of the Subcontinent, representing wisdom and beauty. It is also believed the Devas descend to bathe in the lake between 3 and 5 am the time of the day known as Brahma Muhurta.
