A temple dedicated to Goddess Ganga is located near a sacred stone where King Bhagiratha worshipped Lord Shiva. According to Hindu culture, Goddess Ganga took the form of a river to absolve the sins of King Bhagiratha's predecessors, following his severe penance of several centuries. Bhagiratha Shila is a sacred slab where king Bhagiratha meditated. Ganga is believed to have touched earth at this spot. According to another legend, Pandavas performed the great ‘Deva Yagna‘ here to atone the deaths of their kinsmen in the epic battle of Mahabharata. Hindus believe that performing the ancestral rites on the banks of Bhagirathi frees the spirit of the ancestor from the cycle of rebirth and a holy dip in its waters cleanses sins committed in the present also past births.

The Gangotri temple opens on the auspicious day of Akshaya Tritiya which falls in the month of May and closes on Yama Dwitiya or Bhai Dooj which falls in the month of November. The Gangotri temple remains closed for the rest of six months. The Goddess shifts to the village Mukhba during the winter months. In the month of May, Ganga Dussehra is celebrated with great fanfare as the day of the birth of Ganga.
