The Shiva temple of Umananda is situated atop the Bhasmachala Hill or the Hill of ashes on the picturesque Peacock island in the midst of river Brahmaputra. This hillock- island is also known as Bhasmachal. Legend has it that Lord Shiva burnt Kamdev (God of Love) into ashes with his wrathful eyes on this hill, when he and his wife Rati tried to disturb Lord Shiva in his deep meditation.

The Umananda temple built in the 17th century by an Ahom king, has some fine rock cut figures. It was renewed later in the 20th century following its destruction during an earthquake. Umananda temple can be reached by crossing the river via country boats plying from Kachari Ghat in Guwahati. Regular ferry services are available from 7am to 5pm. Large number of devotees are attracted towards the temple premises especially on the occasion of the annual Shivaratri festival.
