The Alaknanda River, which originates in the eastern slopes of glacier fields of Chaukhamba, is joined by the Saraswathi River near Mana (that originates on the south from the international border), and then flows in front of the Badrinath temple, one of the most revered Hindu shrines. It then meets the Dhauli Ganges River, whose origin is from the Niti Pass, after traveling a distance of from its source to form the Vishnu Prayag (). This stretch of the Alaknanda River is called the Vishnu Ganges. Legend narrates the worship offered by sage Narada to god Vishnu at this confluence. An octagonal shaped temple - located near the confluence - dated to 1889, is credited to Maharani of Indore - Ahalyabai. Though originally built to install a Shiva linga, it now houses a Vishnu image. A stairway from this temple leads to the Vishnu kund (kund means pool of water or lake) at the confluence, which is seen in a tranquil state.
