Gomukh is a beautiful place which marks the end of the Gangotri Glacier. It is located in the Uttarkashi District of Uttarakhand. This place is situated near the Shivling Peak, which is well known for its challenging climbing trails. River Bhagirathi, an important tributary of River Ganga, originates at Gomukh. The place is situated near the Tapovan meadow and enchants visitors with its natural glory.

Hindu mythology considers River Bhagirathi as the mother-stream of River Ganga, while the merger of both the rivers Alakananda and Bhagirathi at Devprayag gives rise to the fullness and exuberance of the waters of Ganga.

Gomukh Mythology 

According to legends Kind Bhagiratha did severe penance, pleased Lord Shiva and asked for the holy river Ganga to come to earth in order to cleanse the ashes of his ancestors. Goddess Ganga agreed and came to the earth in the form of Gangotri glaciers and travelled all the way to Haridwar and granted salvation to King Bhagiratha’s ancestors. Since it was Bagiratha who brought Ganga to the earth, the river is called Bhagirathi. People trek up to the spot for the holy dip.

The Gangotri glacier is one of the biggest glaciers of the Himalayan regions and the starting point of the glacier resembles a cow’s mouth, this place hence came to be known as Gomukh or Gaumukh.
