The road distance from Chennai to Munnar is 617 km via NH544 — a long day that needs an early start.
You cross 6 toll plazas across Tamil Nadu, Kerala. For a car the published fees add up to ₹275 one way, about ₹0.45 per km, cheaper than most highway corridors. 1 plaza on this route does not publish fees in the NHAI dataset; budget about ₹80 extra to be safe.
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.
