One of the 108 Siddha Peeths, this Devi Temple is 21 kms from Tanakpur, Tunyas is 17 kms and from there 3 km trek leads to Purnagiri Temple. Tanakpur is linked by direct bus service with Lucknow, Delhi, Agra, Dehradun, Kanpur and other Districts.
According to an ancient legend, Daksha Prajapati organised a sacrificial ceremony, for which he invited everybody except Lord Shiva. Parvati on discovering that it was her father’s trick to humiliate her husband immolated herself in the sacrificial fire. While her husband carried her body, the places where the parts of her body fell were recognized as Shakti Peeth. The Shakti Peeth holds the prime position among Malikagiri, Kalikagiri, and Himlagiri Peeths.
During Navratras, in the Chaitra month of the Indian calendar, devotees in large number come here to have their wishes fulfilled. After worshipping Mata Purnagiri, people also pay their tributes to her loyal devotee Bada Sidth Nath at Brahmadev and Mahendra Nagar in Nepal.
