Frequently Asked Questions
The Kolli Hills, also known as Kolli Malai, are a mountain range located in the Namakkal district of Tamil Nadu in southern India. Often described as an 'Emerald Fortress,' this region rises sharply from the surrounding plains as a massive, flat-topped wall of rock. It is celebrated for its ancient geology and a mystical atmosphere that shifts from the heat of the plains to a cool, misty climate as you ascend the rugged terrain.
To reach the top of the Kolli Hills, travelers must navigate a legendary road featuring seventy hairpin bends. This challenging climb takes visitors from the hot Namakkal plains into a hidden world with a completely different air and environment. The name Kolli Malai historically refers to the mountain's hostile nature, a nod to the rugged terrain and sheer beauty that could be difficult for unsuspecting outsiders to navigate in the past.
The Kolli Hills are known as the 'Black Pepper Capital' of the region due to their unique and thriving agriculture. In this area, black pepper vines grow in a distinct way, literally wrapping around trees as if they are hugging them. This incredible intersection of tribal culture and specialized farming makes the hills a significant agricultural hub in southern India, offering a glimpse into some of the most unique plant cultivation in the state of Tamil Nadu.
