One of the highlights of a visit to humble Chiang Rai is the new clocktower light show. Each evening from 7-9, on the hour (so at 7, 8 and 9pm) you get a song and a dance, accompanied by colored lights.
If you plan ahead, you can stroll down the market lane from the old clocktower to the new clocktower, and if the season is right, you can get a mango sticky rice to enjoy at the show.
