Kolli Hills, also known as Kolli Malai, is a small mountain range in Central Tamil Nadu, India, that spans the Namakkal and Tiruchirapalli districts. The mountains reach a height of 1300 m and span an area of about 280 km. It is 43 kilometers from Namakkal and 120 kilometers from Trichy. Because of the Arapaleeswarar temple, the mountain is a major pilgrimage place, but the location is also popular with motorcyclists due to the high altitude motor-able terrain with 72 hairpin curves.
