It is said to be one of the toughest pilgrimage due to some reason. There is also a vast change in altitude while travelling from one place to another. It starts from 1050 mts and reaches to the highest of 5000 mts in Roopkand. Also at the beginning of the pilgrimage it rains quite heavily, which the people consider to be the result of their Goddess Nanda Devi’s crying as she has to leave her maternal home to go to the paternal house. The passing of the Roopkand is also another challenge as it is called the mysterious Lake. Usually people do not inhabit near it still there are skulls and skeletons found near the lake which is supposedly of centuries back. However, these obstacles doesn’t stop the numerous of believers to take the pilgrimage and show their devotion to their Goddess. It also brings together all the tribes of the northern part of India specially those of Gharwal and Kumaon region. All the people gather at the Nauti village on the morning to start the Nanda Devi Rat Jat Yatra with great reverence in their hearts and faith is what keeps them going on for the whole 19 days of it.
