Current Advisories
Exercise caution at waterfalls during rain
Water levels at Agaya Gangai, Masila and other falls can rise suddenly during and after rainfall. Do not enter the water when it is muddy or fast-flowing.
Drive carefully on the 70 hairpin bends
The ghat road up to Kolli Hills has 70 sharp hairpin bends. Drive slow, honk at blind curves, and avoid the climb after dark or in heavy fog.
About Kolli Hills
Kolli Hills (Kolli Malai) is a small, unspoiled mountain range rising from the plains of Namakkal district in Tamil Nadu. At around 1,000–1,300 metres, it stays pleasantly cool through the year and is known for its dense forests, medicinal herbs, jackfruit, pineapple and hill coffee.
Less commercial than many South Indian hill stations, it rewards travellers who enjoy nature, gentle treks, waterfalls and a slower pace.
