Gangotri, the source of the river Ganga and seat of the goddess Ganga, is one of the four sites in the Char Dham pilgrimage circuit. The river is called Bhagirathi at the source and acquires the name Ganga from Devprayag onwards where it meets the Alaknanda. The origin of the holy river is at Gaumukh, set in the Gangotri Glacier, and is a 19 km trek from Gangotri. Gangotri can be reached in one day's travel from Rishikesh, Haridwar or Dehradun, or in two days from Yamunotri, the first site in the Char Dham circuit. More popular and important than its sister site to the east, Gangotri is also accessible directly by car and bus, meaning that it sees many more pilgrims than Yamunotri.

This small town is centered around a temple of the goddess Ganga, which was built by the Gorkha General, Amar Singh Thapa in the early 18th century [1]. The temple is closed on Diwali day every year and is reopened in May. During this time, the idol of the goddess is kept at Mukhba village, near Harsil.

Ritual duties are supervised by the Semwal family of pujaris. The aarti ceremony at the Gangotri is especially impressive, as is the temple, a stately affair that sits on the banks of the rushing Ganga. Adventurous pilgrims can make an overnight 18 km trek to Gaumukh, the actual current source of the river Ganga.
