This temple is situated at a height of 2,600 metres (8,500 ft), right at the base of Pir Panjal Range in the Chamba Valley.
It is believed a huge rock in high Pir Panjals at Charola split vertically to reveal three Trishuls, which can still be seen there.
After this, the goddess found her next home at Lyundi, at the base of the Pir Panjals and finally settled in the village of Banni.
Pilgrims from all over the Bharmour region and other parts of Himachal find their way to the temple to pay obeisance to the goddess.
It is believed Goddess Kali grants all wishes and gives children to couples who don't have anyone, making the journey with total devotion and fervor.
Sometime around August, in the Bhadrapad month of the Hindu calendar, a fair is organized at the temple and it attracts devotees from all around.
In recent times, the pilgrimage to Banni Mata has become much easier with a road approaching Tundah, which leaves only 4 km to walk.
