Siddhavata at Ujjain is well known for its sanctity as Akshayavata of Prayag, Vamshivata of Vrindawan and Panchavata of Nasik. Post funeral rites are performed here at the Siddhavata ghat of holy Shipra. Skanda-purana has referred to this place as preta-shilla-tirth. According to some opinion Parvati performed her penances here. This has also been a place of worship for the followers of Nath sect.
Shipra abounds in tortoises at Siddhavata. Old coins of Ujjain are found to bear the imprintof tortoises along the river. This is also indicative of the fact that the tortoises must have flourished here even in the ancient period. It is said that Banyan tree was once sought to be vanished by cutting it off and covering it with iron sheets but its offshoots pierced through the iron sheets and this tree regained its foliation.
