This was an easy day in terms of driving, The road from Chiang Rai to Chiang Mai was easy and should not take longer than 3h. I still got up early, mainly to see the White Temple in the morning since I was passing by anyway.
You can compare the photos but I think the best time to visit is in the afternoon before sunset, light is better in my opinion and there are less people but your preference might vary.
The rest of the road was pretty uneventful, aside from me filling up my memory cards after not being able to offload my photos to my Surface for the past days.
Once I got to Chiang Mai, I met up with an old friend and we spent the afternoon and evening catching up and having beers.
