Kolli Hills Road (also known as Kollimalai Ghat Road) is an extremely dangerous mountain road with a length of 46.7 km located in Kolli Hills or Kolli Malai, a small mountain range located in central Tamil Nadu in Namakkal district on the east coast of South India. The road includes 70 continuous hairpin bends.
The road starts in Kalappanaickenpatti. 70 continuous hairpin bends take you to Kolli Malai or ‘the mountains of death’. Riding through these hairpin bends is an exhilarating experience. Up to around the 25th hairpin bend, the road is great. After that the road is quite bad - pot holes and patches. Some of the hairpin bends are very narrow and do not have space for two vehicles to take the turn. The views of the plains below are beautiful and the dense green tropical forests surrounding the hairpin bends adds to the charm. The road is a ghat road: the name of the access routes into the mountainous Western and Eastern Ghats mountain ranges of the Indian Subcontinent. These roads are remarkable feats of engineering and most date back to British times. Ghat roads were built to connect to the famous Hill Stations of the Indian Subcontinent.
This road is very exciting and sometimes very exposed and unsecured driveway in innumerable twists and turns. The roads are pretty decent except for some slightly bad stretches hitting the hairpin bends. The 70 hairpin bends, which are spread across a little more than fifteen kilometres are nearly continuous and it is indeed a pleasure to drive on these winding roads.
