Nanda Devi (Hindi: नन्दा देवी ) is the highest mountain in Uttarakhand, the second highest mountain in India and the highest entirely within the country (Kangchenjunga being on the border of India and Nepal); owing to this geography it was considered the highest known mountain in the world until computations on Dhaulagiri by western surveyors in 1808. It was also the highest mountain in India before Sikkim joined the Republic of India. It is part of the Garhwal Himalayas, and is located in the state of Uttarakhand, between the Rishiganga valley on the west and the Goriganga valley on the east. Its name means Bliss-Giving Goddess. The peak is regarded as the patron-goddess of the Uttarakhand Himalaya.
