267 km · 0 toll plazas · about 7 h 10 min on the road. Change the vehicle, fuel or mileage below and every number updates.
The road distance from Alleppey to Kodaikanal is 267 km via Kollam - Theni Highway — doable in a single day with a couple of breaks.
Our data shows no toll plazas on the fastest route, so the cost of the drive is essentially fuel. On a drive this long that is unusual: if you switch to a national highway or a new expressway you may meet plazas that aren't in the NHAI dataset yet, so keep a small buffer.
Kodaikanal is a hill destination: the last stretch climbs ghat roads, where mileage drops by roughly 15–25% and speeds fall sharply. Our fuel figures use flat-road mileage, so add a buffer.

None on the fastest route, according to NHAI's plaza list.
About 18 litres for a car doing 15 km/l (₹2,037 at Alleppey prices). A hatchback at 18 km/l needs ~15 L; an SUV at 11 km/l needs ~24 L.
Around ₹2,037 one way for a petrol sedan (fuel ₹2,037 + toll ₹0), or ₹4,073 for a same-day return. Split between four people that is ₹509 each, one way.
Plan on about 7 h 10 min including short breaks. Free-flowing traffic can do it in 5 h 6 min, but towns, trucks and plaza queues usually add time.
No toll plazas sit on the fastest route, so commercial vehicles pay no toll either.
Yes, plazas charge the same fee in both directions, so the Kodaikanal to Alleppey toll is the same ~₹0 for a car. Fuel cost differs only if you fill up at Kodaikanal's state price.
Fees are revised every 1 April and some plazas change mid-year, so treat results as a close estimate. Spotted a wrong fee or a missing plaza? Tell us — we fix reported errors within 72 hours and log them on our corrections page.
