It is said that the hill got its name after a wild elephant, Kari attacked and killed four girls taking bath. To bring them back to life Sage Kutsamuni undertook a rigorous penance and requested the Lord to save His devotees. Another legend has it that during the building of the bridge to Lanka to bring back Sita, Sugreeva brought this hillock, also called ‘Neelachala’ from Tirumala (Thirupathi). On his way several Vishnubhakhtas (disciples of Lord Vishnu) pleaded with him to leave it here and so the hill remained here.
