Umamaheshwaram (Telugu: ఉమామహేశ్వరము, also known as Maheshwaram and Umamaheshrum) is a temple dedicated to the Hindu god Shiva in Andhra Pradesh, India. It is in the picturesque Nallamala forest range around 100 kilometers away from Hyderabad on the Hyderabad-Srisailam highway.
Umamaheshwaram is the northern gateway of Srisailam — one of the jyotirlingas. It is mentioned in many Vedas that visit to a Srisailam without Umamaheswaram is incomplete. It is atop the hill properly covered by huge trees. Hill ranges shields the temple and 500 metres of stretch to PapaNasanam. Through the day hardly any sunlight falls on this stretch, thus maintaining the temperature below normal year round. It is popularly known as Poor Man’s Ooti.(wiki)
