The shrine of Yamunotri, situated at an elevation of about 3,235 m is a point of paramount religious importance for Hindus and an essential pilgrimage. Situated in the direction opposite to Gangotri, the road bifurcates from a place called Dharasu, somewhere between Rishikesh-Uttarkashi and goes on to Yamunotri. The shrine can also be visited via Mussoorie and Barkot. The distance of Yamunotri is about 222 kms from Rishikesh. The actual source, a frozen lake of ice and glacier (Champasar Glacier) located on the Kalind Mountain at a height of 4,421 m above sea level, about 1 km further up, is not frequented generally as it is not accessible; hence the shrine has been located on the foot of the hill. The approach is extremely difficult and pilgrims therefore offer puja at the temple itself.
The temple of Yamuna, on the left bank of the Yamuna, was constructed by Maharaja Pratap Shah of Tehri Garhwal. The deity is made of black marble. The Yamuna, like the Ganges, has been elavated to the status of a divine mother for the Hindus and has been held responsible for nurturing and developing the Indian civilization. Close to the temple are hot water springs gushing out from the mountain cavities. Surya Kund is the most important kund.
Near the Surya Kund there is a shila called Divya Shila, which is worshipped before puja is offered to the deity. Devotees prepare rice and potatoes, tied in muslin cloth, to offer at the shrine by dipping them in these hot water springs. Rice so cooked is taken back home as prasadam. The pujaris of Yamunotri come from the village of Kharsali near Janki Chatti. They are the administrators of the sacred place and perform religious rites. They are well-versed in the Shastras.
According to the legend ancient, sage Asit Muni had his hermitage here. All his life, he bathed daily both in the Ganges and the Yamuna. Unable to go to Gangotri during his old age, a stream of the Ganges appeared opposite Yamunotri for him.
The temple and the place opens every year on the auspicious day of the Akshaya Tritya, which generally falls during the last week of April, or the first week of May. The temple always closes on the sacred day of Diwali in mid-October - first week of November, with a brief ceremony. The temple staff return to their villages and for the rest of the time the valley is gripped in no-man silence and covered with a white sheet of snow. With the melting of the snow next summer, the temple re-opens to the blissful happiness of thousands of visitors again.
The daughter of the Sun god, Surya and consciousness, Sangya the birth place of the Yamuna is the Champasar Glacier (4,421 m) just below the Banderpoonch Mountain. The mountain adjacent to the river source is dedicated to her father, and is called Kalind Parvat, Kalind being another name of Surya. Yamuna is known for her frivolousness, a trait that she developed because, according to a common story, Yamuna's mother could never make eye contact with her dazzling husband.
In summer the maximun temp is 18 degrees and the minimum is 10 degrees celsius. The days are pleasantly cool but the nights are cold.
