The three week long Nandadevi Rajjaat is one of the world famous festival of Uttarakhand. People from entire Garhwal-Kumaon as well as other parts of India and the world participate in Nandadevi Rajjaat Yatra.
Goddess Nanda Devi is worshipped at dozens of places in Kumaon, but the region around Mt. Nanda Devi and its sanctuary, which falls in the districts of Pithoragarh, Almora and Chamoli, is the prime area related to Nanda Devi. In Chamoli Nanda Devi Rajjaat is organized once in 12 years.
The jaat starts from Nauti village near Karnprayag and goes upto the heights of Roopkund and Haemkund with a four horned sheep. After the havan-yagna is over, the sheep is freed with decorated ornaments, food and clothings and the other offerings are dischared.
People also celebrate the annual Nanda jaat. Though in the Johar region there is no tradition of Nanda Rajjaat but the worship, dance and the ritual of collecting Brahmkamals (it is called Kaul Kamphu) is part of Nanda festivals. It is one of the festival in which people covers such a long walking distance because of this it comes under a unique record.
