Getting from Chennai to Kolli Hills – Main Options

Train

Taking a train is a comfortable and economical way to travel part of the distance from Chennai to Kolli Hills. However, there is no direct train to Kolli Hills, so you will need to combine train travel with road transport.

• The nearest major railway station to Kolli Hills is Namakkal Railway Station, about 40 km away, connected by regular trains from Chennai Central and Chennai Egmore stations.

• Train journey from Chennai to Namakkal typically takes around 6 to 8 hours, depending on the train service chosen, with fares ranging from ₹150 to ₹600 for sleeper and AC classes.

• Trains are frequent but can be crowded during weekends and festival seasons; booking tickets in advance via IRCTC is recommended to secure preferred classes.

• From Namakkal station, you can hire a taxi or take a local bus to Kolli Hills, which takes about 1.5 to 2 hours on winding hill roads.

• Monsoon season may cause occasional delays on the rail route due to waterlogging or track maintenance, so check train running status before travel.

Bus

Buses offer a direct and affordable option to reach Kolli Hills from Chennai, though the journey is long and can be tiring. Both government and private buses operate on this route.

• State-run TNSTC buses and private operators run from Chennai’s Central Bus Stand (Puratchi Thalaivar Dr. M.G.R. Bus Terminus) to Namakkal or directly to Kolli Hills during peak tourist seasons.

• The bus journey covers approximately 350 km and takes around 8 to 10 hours, depending on traffic and road conditions, with fares ranging from ₹300 to ₹700.

• Volvo and deluxe buses provide more comfort and fewer stops, while ordinary buses are cheaper but more crowded and slower.

• Night buses are available, which can help save daytime hours, but road conditions on the hill section after Namakkal require careful driving.

• During monsoon, the hilly roads may be slippery, so bus services may be slower or temporarily suspended; check local updates before traveling.
