Thinking of going to Nan in the morning. Those who have driven there before, what route would you recommend? I would say the quickest rather than most scenic. Thanks in advance.

The "southern" route is fastest, via Lampang and Phrae. It is not the shortest route, but the roads are good all the way (except for some possible road works between Phrae and Nan).

 

Can I mention Nan Noble House Garden Resort as a place to stay. I declare my interest, which is that a friend owns it, but it is a very nice place to stay.

Agreed, southern route. After Lampang, on the highway towards Den Chai, take the left turn 1023 via Long to Phrae, light traffic and good road, better than continuing down the 11.

It was quicker for me going via Phayao.

Quick and very scenic go to Phayao and turn east on the 1021 before the lake.  Then take a right heading southward on the 1251 (you might have to ask to find that turn) and then a right on the 1091 all the way to Nan.  Yes, you will need to invest in a good road map of one sort or another.

I, too, say the Lampang/Phrae road. Fast, smooth, not so much traffic  Rt.11 into Rt.101 right into the middle of Nan.  Took about 4 hours.
