Chennai's road trips fall into three groups. South along the coast, the East Coast Road leads to Mahabalipuram, Pondicherry and eventually the old Danish town of Tranquebar. Inland, the temple towns of Kanchipuram, Tiruvannamalai and, further south, Thanjavur and Kumbakonam make rewarding drives. To the west, the Eastern Ghats rise at Yelagiri, and the long highways lead to Kodaikanal and Ooty.
Tamil Nadu's roads are generally good, but summer heat and the north-east monsoon (October to December) need planning.
Quick answer
The best road trips from Chennai are Mahabalipuram (about 55 km), Kanchipuram (about 75 km), Pulicat (about 60 km), Pondicherry (about 150 km on the East Coast Road), Yelagiri (about 230 km), Tiruvannamalai (about 190 km), Tranquebar (about 280 km), Thanjavur (about 350 km), Chettinad (about 400 km), and Kodaikanal or Ooty (530 to 560 km). November to February is best; avoid the heavy north-east monsoon and summer heat.
Key takeaways

- Yelagiri is the nearest hill station, about four to five hours away.

Planning a long weekend
With three days, pair Mahabalipuram with Pondicherry, or Kanchipuram with Tiruvannamalai. With four or five days, continue down the coast from Pondicherry to Chidambaram and Tranquebar, then inland to Thanjavur, returning via Tiruchirappalli. For the hills, Yelagiri is a weekend trip; Kodaikanal needs at least four days by road.
Tips for driving out of Chennai
- Leave early to beat traffic on the ECR, GST Road and the Bengaluru highway.
- Carry water and plan midday breaks from April to June, when heat is intense.
- Check cyclone and rain warnings from October to December.
- Temple towns have dress codes and footwear rules; keep a change of clothes in the car.
Food on the road
Chennai's highways are lined with vegetarian hotels serving idli, pongal and filter coffee for breakfast and banana-leaf meals at lunch. Karaikudi and the Chettinad villages are famous for their spiced meat and vegetable dishes, Pondicherry for its cafés and Creole cooking, and the ECR for fresh seafood at simple shacks near the fishing villages.
Coming back
- Return traffic on the ECR and GST Road is heavy on Sunday evenings; start back after lunch or on Monday morning.
- Keep the FASTag topped up for the ECR and national highway tolls.
When to go
November to February is best, with mild temperatures; November can still be wet. March to June is hot and humid. The north-east monsoon (October to December) brings Chennai's heaviest rain, with flooding and cyclones in some years.
Safety
- Mountain roads close or slow down after heavy rain, snow or landslides; check road status and weather updates each morning and avoid driving after dark.
