Lake Manasarovar is among the world’s highest fresh-water lakes. At an elevation of 4,583 meters, the lake covers 412 square kilometers. With the northern part broader than the southern end, the deepest point of the lake is over 70 meters. The lake is purer than a sapphire and one can see through dozens of meters into the lake. The lake is located in the Burang County, 20 km southeast of the Mount Kailash. According to Hindu religion, the Mansarovar lake was first created in the mind of the Lord Brahma. Hence, in Sanskrit it is called "Manasarovar", which is a combination of the words Manas and Sarovar. The lake, in Hindu mythology, is also supposed to be the summer abode of swans, who are considered as very wise and sacred water birds. 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,Brahma auspicious time. Located at the southern base of Mount Kailash, Lake Manasarovar is famed for its exceptional beauty. Its color changes from a clear blue around the shores to a deep emerald green in the center; it looks positively magical in the moonlight. The lake is 55 miles (88 km) in circumference, 330 feet (90m) deep, and 120 sq mi (320 sq km) in total area. The journey around the lake is 64 miles long and usually takes four days. Many travelers opt to pitch a tent by the lake for a couple days instead, recuperating from the strenuous journey around Mount Kailash.
