The hill is sacred to the Irula, Bagada and the Kurumba tribes of the Nilgiris. The peak is dedicated to the deity Rangaswamy. Two shrines– one for Lord Ranga and the other for His consort are located here. According to Hindu legends, Lord Rangaswamy used to live at Karamadai (Coimbatore district) on the plains, but quaralled with his wife and came to live alone here. Two foot prints on the rock not far at Arakadu village below the peak are believed to be evidences for this.
