Mana Pass is located within the Nanda Devi Biosphere Reserve, 24 km north of the town of Mana, India and 52 km north of the Hindu pilgrimage town of Badrinath in Uttarakhand. It is the source of the Saraswati River, the longest stem of one of the longest Ganges tributaries, the Alaknanda River. That river trickles through several scenic small ponds between the pass and Lake Deo Tal three km southwest of the pass. Mana pass is also the key col for climbing Chaukhamba peak.
