It is a conical peak at a height of 5855 feet above MSL and is the most sacred hill on the plateau. According to Hindu Legend Lord Rangaswamy used to live at Karamadai in Coimbatore district on the plains but quarrelled with his wife, came to live alone here. Two-foot prints on the rock not far from Arakadu village below the peak are stated to be the proof for this.

On the north west of Rangaswamy Peak is found the Rangaswamy Pillar, which is an extraordinary isolated rocky pillar rising in solitary grandeur to a height of some 400 feet and has sheer sides, which are quite unclimbable.
