Coimbatore to Munnar is a comfortable one-day drive of 153 km.
You cross 1 toll plaza across Tamil Nadu, Kerala, but none of them publishes fees in the NHAI dataset (they are mostly state or municipal plazas). Based on typical highway fees we estimate about ₹80 for a car — treat it as a budget, not an exact figure.
Munnar 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.

1 on the fastest route: Chinnar 9/6 checkpost.
About 10 litres for a car doing 15 km/l (₹1,111 at Coimbatore prices). A hatchback at 18 km/l needs ~9 L; an SUV at 11 km/l needs ~14 L.
Around ₹1,191 one way for a petrol sedan (fuel ₹1,111 + toll ₹80), or ₹2,382 for a same-day return. Split between four people that is ₹298 each, one way.
Plan on about 4 h 25 min including short breaks. Free-flowing traffic can do it in 3 h 13 min, but towns, trucks and plaza queues usually add time.
One way with FASTag: bus/2-axle truck ₹260, 3-axle ₹305, 4–6 axle ₹415, 7+ axle ₹500 (includes estimates for plazas without published fees).
Yes, plazas charge the same fee in both directions, so the Munnar to Coimbatore toll is the same ~₹80 for a car. Fuel cost differs only if you fill up at Munnar'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.
