Daitya Sudan Temple is located near the Lonar crater – the world’s only salt water lake in basaltic rock, believed to have been caused by a meteorite hitting Earth around 52, 000 years ago.  It is surrounded by forests with a large variety of birds, particularly peacocks, owls, red-wattled Lapwings and ducks.  A number of temples surround the lake, most of which stand in ruins today. 

According to local belief, Lonar derives its name from the mythical demon Lonasura (also called Lavansura).  This demon used to harass and trouble the local people so much that Lord Vishnu descended to earth to vanquish him.  The crater, and the lake that now fills it, was formed when Lonasura was pushed back into the netherworld with tremendous force by Vishnu!
