Yamunotri is a place where Yamuna river start to appear and it is defined as a Yamunotri.It is source of Yamuna River and considered as a seat of the Goddess Yamuna in Hinduism. Yamunotri is situated amidst the Garhwal Himalayas in the state of Uttarakhand and is blessed with natural beauty and charm. It is situated at an altitude of 3,293 metres (10,804 ft) in the Garhwal Himalayas. The actual source of Yamuna River is located on the Kalind Mountain at a height of 4,421 m above sea level, due to accessibility to the source it is extremely difficult so pilgrims therefore offer puja at the temple itself.
The temple devoted to Goddess Yamuna was constructed by Maharaja Pratap Shah of Tehri Garhwal. The shrine deity at the Yamunotri temple is made up of black marble. The Yamuna is considered to be one of the divine mother like the Ganges for the Hindus and has been held responsible for nurturing and developing the Indian civilization. There are two holy thermal springs close to the temple. In these two hot springs, one is considered as a Surya Kund which has boiling water properties where the Gauri Kund has lukewarm water suitable for bathing. Between these two Kund's, Surya Kund is the most important where there is Shila called Divya Shila, which is worshipped before puja is offered to the deity.
Every Year the temple opens on Akshaya Tritiya (in the month of May) and closes on Yama Dwitiya (the next day of Diwali in November). During this period, the pilgrims come here to take the blessing of Yamuna, who according to Hindu mythologies is the sister of God of Death Yama. The holy dip in this river secures a painless death to the devotee's.
