Hi Guys

I plan to visit CM with friends later this year, and probably will drive by car from Ayutthaya.

Just wondering - what's the best/shortest/fastest way?

Ayuttaya- Ang Thong - Singburi - Uthai Thani - Nakon Sawan- Kamphaeng Phet - Tak - Lampang - Chiang Mai. This seems to be the fastest route and when I use it from CM - Bkk it usually takes around 7 hours.

Yup, agreed. Basically it's following Highway #1 all the way to Lampang, where you turn left on to Highway #11 to Chiang Mai.

Google Maps will show this as well if you plug in the departure and destination.

If you want to stop somewhere, Kamphaeng Phet is interesting.

Thanks guys - much appreciated!

Agree with the route, drove most of it twice last week. The stretch from the 'border' of Khampaeng Phet province to Tak city is a nightmare due to the road surface breaking up badly. This makes large trucks & VIP buses swerve all over the place & even Fortuners were driving inside the inner safety median!!! This happens again just after you enter Lampang province, but only for a few kms. Apart from that it is a breeze, visually scenic & the food court at the PTT garage just outside Khampaeng Phet is clean, the food tasty, the Amazon Coffee shop serves good hot & cold drinks and the toilets are clean. Enjoy the trip.
