Driving tips to Munnar from Bangalore via Dindigul: 500 km

Bangalore –> 40km –> Hosur –> 50km –> Krishnagiri –> 110km –> Salem –> 93km –> Karur –> 74km –> Dindigul –> 58km –> Periyakulam –> 16km –> Theni –> 16km –> Bodinayakanur –> 50km –> Munnar

This is one of the longish, but a popular road option to drive from Bangalore to Munnar.

Of the 510km total distance from Bangalore to Munnar, you'll be on the NH7 well over 350km.

What this means is though its a longish route, you could cover the distances quite fast compared to the other other two road options (see Bangalore to Munnar via Erode and Bangalore to Munnar via Chamarajanagar), thanks to the 4 lane highway.

From Dindigul, take the right diversion to NH45 towards Theni. This too is an excellent highway compared to NH7. At Theni, take the diversion for NH49. The last 60km after Bodinayakanur, the road winds through the plantations and ghat sections, and slower too.

Alternatively after Karur you can leave exit NH7 at Aravakurichi and head for Dharapuram. From Dharapuram head to Udumalpet and then to Munnar via Marayoor.

The Aravakurichi to Udumalpet route, though 2 lane is reasonably good to drive.
