When we first did this trip, we walked out of Chennai airport, took the metro to Koyambedu and hopped on the first bus to Pondy. Easy. Try the same today and you might end up at the wrong bus stand, 30 km from where your bus actually leaves. Since 2024, Chennai has split its long-distance buses between two terminals – and that changes everything about getting from Chennai to Pondicherry.
This guide covers every option in 2026 – bus, train, cab and self-drive – with the right bus stand for each route, real fares and travel times, and the fastest way to get there straight from the airport. Pondicherry (officially Puducherry) is about 150 km from Chennai, so whichever option you pick, you’ll be there in three to four hours.
First, decide which road you want to take.
Chennai to Pondicherry Distance: ECR vs the Highway
There are two road routes between the cities, and they feel completely different.
East Coast Road (ECR) – about 150 km
The ECR hugs the Bay of Bengal past Kovalam, Mahabalipuram, Kalpakkam and Marakkanam. Expect fishing villages, casuarina groves, salt pans and glimpses of sea – the reason most travellers pick this route. It’s a two-to-four-lane road with lots of small towns, so the drive takes about 3–3.5 hours. Plan a stop at Mahabalipuram (about 55 km from Chennai) for the Shore Temple and Arjuna’s Penance.
GST Road / NH 32 via Tindivanam – about 160 km
The inland route runs down the Grand Southern Trunk (GST) Road through Tambaram and Chengalpattu to Tindivanam, then turns east to Pondicherry. It used to be called NH 45, and you’ll still see that name on older blogs. It’s about 10 km longer but mostly a wide divided highway with tolls, so it’s often just as fast – especially when ECR traffic builds up on weekends.
Which should you choose?
- Pick ECR if the journey is part of the trip, or you want to stop at Mahabalipuram.
- Pick the highway if you’re in a hurry, travelling at night, or leaving from south Chennai, Tambaram or the airport.
Whatever you choose, the route also decides which bus stand you need – so read the next section before heading out.
Chennai to Pondicherry Bus: Which Bus Stand, Fares and Timings
Buses are still the cheapest and most flexible way to make this trip. They run all day and through much of the night, roughly every 15–30 minutes. The catch is knowing where to board.
Two bus stands, two routes
- Kilambakkam (Kalaignar Centenary Bus Terminus, KCBT) – since early 2024, government buses to the south that run via Chengalpattu and Tindivanam leave from here, including Pondicherry buses on the highway route. It sits on GST Road near Vandalur, about 30 km south of the city centre.
- Koyambedu (CMBT) – buses running via ECR still leave from Koyambedu, and they also pick up along the ECR at stops such as Thiruvanmiyur and Sholinganallur.
During festival seasons like Pongal, the government sometimes moves departures to temporary stands, so check the TNSTC or SETC website, or ask at the enquiry counter, before you travel.
Types of buses and 2026 fares
Prices vary by operator and season, but expect roughly:
- Ordinary and deluxe (non-AC) government buses – about ₹150–200.
- AC government buses (SETC/PRTC) – about ₹250–450.
- Private AC seater and Volvo buses – about ₹300–600, bookable on redBus and AbhiBus.
The journey takes 3–4 hours, depending on Chennai traffic. Government buses arrive at the Pondicherry New Bus Stand on Maraimalai Adigal Salai, about 2 km from White Town – an auto ride of roughly ₹80–150.
Our experience
We took an AC bus down on a hot afternoon and a non-AC deluxe bus back. Both took about four hours. The deluxe bus was fine, apart from its quirky windows, which slid down from the top-fully open or fully shut, nothing in between. Pick AC between March and June; the deluxe is perfectly comfortable the rest of the year.
Buses suit most travellers. But if you’d rather not deal with bus stands at all, there’s a train.
Chennai to Pondicherry by Train
Only one train runs daily on this route, but it’s cheap and reliable:
- 16115 Chennai Egmore–Puducherry Express – departs Chennai Egmore at 6:10 pm, arrives Puducherry at about 10:15 pm. It runs daily and takes about four hours.
- Class: Second sitting (2S) only. Fares are well under ₹150 – the cheapest way to make the trip.
- Return: The matching 16116 runs from Puducherry back to Chennai Egmore in the morning.
A few weekly express trains also connect Puducherry with other cities, but for Chennai, the 16115 is your option.
Is the train worth it? It takes as long as the bus, leaves at only one time and gets in late at night. Take it if you’re already near Egmore, prefer trains to buses, or want the absolute lowest fare. Book on IRCTC a few days ahead for weekend travel; the 2S coaches fill up.
Arriving late? Puducherry railway station is on the southern edge of town, about 1–2 km from White Town. Autos wait outside, but pre-book your hotel and agree on the fare before you get in.
Want the most comfortable option instead? Book a cab.
Going by Cab or Self-Drive
Outstation cab
For groups of three or four, or anyone carrying heavy luggage, a cab is the easiest way to reach Pondy. Expect around ₹2,500–3,500 one way in 2026 for a hatchback or sedan, including taxes; check whether tolls and parking are included before you confirm. Uber, Ola and outstation cab services like Savaari all run this route. The drive takes about 2.5–3.5 hours, depending on traffic and route.
Tell the driver which route you want. Most will default to the highway; if you want ECR and a stop at Mahabalipuram, agree on it (and any extra waiting charge) at the time of booking.
Self-drive
Self-drive rentals from Zoomcar and local rental companies are another option, especially for an ECR road trip. Pondicherry is a separate union territory, and commercial vehicles registered outside Puducherry may pay a small entry tax at the border – check with your rental company. Fuel is usually a little cheaper in Pondicherry than in Tamil Nadu – fill up there for the drive back.
Chennai Airport to Pondicherry
Landing at Chennai airport? Don’t head into the city – both main options start south of it.
Option 1: Airport → Kilambakkam bus (cheapest)
MTC bus MAA1 runs from the airport to Kilambakkam bus terminus roughly every 15 minutes and takes about an hour. From Kilambakkam, board a Pondicherry bus on the highway route. Total time: about 4.5–5 hours; total cost: a few hundred rupees.
Option 2: Airport → Koyambedu by metro (for ECR buses)
Take the Chennai Metro Blue Line from the airport station to Alandur, change to the Green Line and ride to CMBT (Koyambedu); the station opens right onto the bus terminus. The fare is around ₹40–50 in 2026. Chennai Metro is clean, cool and rarely packed – much calmer than Delhi or Mumbai at rush hour. From CMBT, board an ECR bus to Pondicherry.
Option 3: Airport → Pondicherry by cab (fastest)
A direct cab from the airport takes about 3 hours and costs roughly the same ₹2,500-3,500. If you land late at night, this is the safest choice.

Do’s

- Book private buses and the train in advance for Friday evenings and long weekends.
- Stop at Mahabalipuram if you’re on ECR – it adds only an hour or two.
Don’ts
- Don’t go to Koyambedu expecting every Pondicherry bus – the highway services moved to Kilambakkam.
- Don’t accept an auto in Pondicherry without agreeing on the fare first.
- Don’t drive the ECR at night unless you know it – the road is unlit in stretches and busy with two-wheelers.
