Mansa Devi Temple, Haridwar, Hindu temple on Bilwa Parvat, Haridwar, India.

Mansa Devi Temple is a Hindu temple on Bilwa Hill in the city of Haridwar in Uttarakhand state. The main shrine displays two separate figures of the goddess, one with eight arms and the second with three heads and five arms.

The sources describe Mansa Devi Temple as one of Haridwar's ancient temples, revered for centuries as a Siddh Peeth where devotees' wishes are fulfilled. It is counted among the Panch Tirth, the five pilgrimages of Haridwar, and stands on Bilwa Parvat in the Sivalik Hills. The temple is linked by the Mansa Devi Udankhatola ropeway, 540 metres long and rising 178 metres, which also serves the nearby Chandi Devi Temple.

Visitors follow the tradition of tying threads to tree branches within the temple complex to mark their wishes and return to untie them upon fulfillment.

The rope-way, called Mansa Devi Udankhatola, runs 540 metres (1,770 ft) from the lower station to the temple and climbs 178 metres (584 ft). The temple is open from 8 AM to 5 PM on ordinary days. Pilgrims can also walk up the hill by a stair path instead of riding.

Visitors tie threads to tree branches within the temple grounds to mark their wishes, returning to untie them once fulfilled. This practice has created a dense web of colored fabric threads in the trees over the years.
