This Raj jat yatra originates from the Nauti village 20 km of Karnaprayag tehsil of Indian state of Uttarakhand. The Kunwar of village Kansua inaugurates the ceremony. The legend is this that Nanda Devi, consort of Lord Shiva left her village and went to the nanda devi parbat. Therefore when the yatra starts, heavy rain occurs as if the devi is crying. This yatra covers many villages and in between the Devi meets her sister in the Bhagwati village.
This yatra is very tough on account the landscape it goes through. In between the yatra there comes a Lake Roopkund where lies the hundreds of skeletons. It is said that once the King took some dancers to this sacred place due to which heavy snow fell and people died and the dancers got transformed into stone which can be sen in Patarnachonia. The other myth is this that king Yasodhwal's wife was pregnant and while she was giving birth to her child, her placenta flowed down to Roopkund and this in turn caused the death of the people on that place. That is why the river Nandakini lost her significance and the Nandprayag is not considered sacred as the other Panch Prayags like Devprayag, Vishnuprayag, Karanprayag and Rudraprayag.
