332 km · 0 toll plazas · about 8 h 30 min on the road. Change the vehicle, fuel or mileage below and every number updates.
The road distance from Trivandrum to Kodaikanal is 332 km — 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.

Petrol is cheapest in Tamil Nadu (₹108.78/L) and dearest in Kerala (₹114.57/L). Filling the ~22 litres you need in Tamil Nadu saves about ₹128 versus buying it all in Kerala.
For the same sedan, fuel for one way costs ₹2,537 on petrol, ₹1,808 on diesel and about ₹949 on electric (public fast charging at ₹20/kWh; home charging is far cheaper). An EV with ~350 km real range needs about 1 charging stop on the way.
Nothing on the fastest route — our data shows no toll plazas between Trivandrum and Kodaikanal. Keep a small buffer in case your route uses a newer highway.
None on the fastest route, according to NHAI's plaza list.
About 22 litres for a car doing 15 km/l (₹2,537 at Trivandrum prices). A hatchback at 18 km/l needs ~18 L; an SUV at 11 km/l needs ~30 L.
Around ₹2,537 one way for a petrol sedan (fuel ₹2,537 + toll ₹0), or ₹5,074 for a same-day return. Split between four people that is ₹634 each, one way.
Plan on about 8 h 30 min including short breaks. Free-flowing traffic can do it in 6 h 8 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 Trivandrum 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.
