Before you drive from Chennai to Kodaikanal, get an e-pass for the vehicle on the state portal epass.tnega.org. The requirement came out of Madras High Court orders on crowding in the Nilgiris and Kodaikanal, and checks happen at the entry points to the hills. Without the pass, entry may be refused, so it is the one step that can wreck a trip if forgotten.
Beyond that, Kodaikanal is a long but manageable journey: there is no railway up the hill, so Chennai travellers ride a train to the plains below and finish by road. This guide covers both legs and the pass.
Getting there from Chennai
- Train: the nearest railway station is Kodai Road in Dindigul district, according to the Dindigul district administration. Dindigul and Kodai Road lie on the main line between Chennai and Madurai, so overnight trains from Chennai are the usual choice.
- Road from the station: the Indian Institute of Astrophysics, which runs the Kodaikanal Solar Observatory, puts Kodai Road about 80 km from the observatory and Madurai about 130 km, in its travel note. The observatory is 4 km from the town. Taxis and buses take about three hours from Madurai.
- Air: Madurai is the nearest airport.
- Driving all the way: a full day each way. Plan to tackle the ghat section in daylight; it is narrow, winding and often in mist.
The e-pass: what the courts ordered
The Madras High Court first directed in 2024 that vehicles entering the Nilgiris and Kodaikanal carry e-passes during the summer peak. On 13 March 2025 it went further and capped daily tourist vehicles for April to June: 4,000 a day on weekdays and 6,000 at weekends for Kodaikanal, and 6,000 and 8,000 for the Nilgiris. On 28 March 2025 the Supreme Court declined to interfere, LiveLaw reported. Government buses, government vehicles, trade vehicles and local residents were exempted from the caps, and electric vehicles get priority.
The Nilgiris district administration has said the e-pass system will continue there until the High Court orders otherwise. The numeric caps were set for the summer season. Rules have shifted with each hearing, so check the portal before travelling at any time of year.
How to apply
- Open epass.tnega.org and choose “Within India” (or “Outside India” for non-residents).
- Enter your mobile number and the captcha, then verify the OTP.
- Choose Kodaikanal as the destination and fill in your personal details, travel dates and vehicle details.
- Read the rules, confirm, and download the pass. It is generated immediately.
- Carry the pass with a valid ID for checks at the entry point.
The steps above follow ETV Bharat’s guide from April 2025, which advises applying at least 48 hours before travel during peak months. No fee was reported for the pass.
What to do once you are up
The town is at about 7,200 feet. The district page lists the lake, where you can row, ride horses or cycle along the shore, the Silver Water Falls and the forests around the town. The solar observatory, set up in 1899, has an astronomy museum.
For walkers, the government’s Trek Tamil Nadu programme lists four Dindigul trails in its July 2026 list. They include the easy 10 km walk from the Kodaikanal Observatory to Gundar Zero Point and the moderate 10 km Kodaikanal to Vellagavi route. All are booked online with forest department guides.
Weather and timing
- The northeast monsoon reached Tamil Nadu on 15 October 2026. Expect showers, mist and occasional landslips on the ghat road until December.
- April to June is the busiest season, when the vehicle caps have applied. Book stays early and apply for the pass well ahead.
- Carry warm clothing in any month; nights are cold.
If you are not driving
Travellers who come up by bus or a hired taxi should still ask about the e-pass. The High Court’s caps excluded government buses carrying tourists, which makes a state transport bus from Dindigul or Madurai the simplest way to avoid the paperwork. A taxi from Kodai Road or Madurai is a private vehicle and will need a pass, so confirm that the operator has applied for one in advance.
Inside the town, roads around the lake are congested at weekends. Many visitors park once and walk or cycle around the lake, which is about the most pleasant way to see it anyway.
