It was far nicer during previous years, but is still worth the experience, particularly if you are looking for original and interesting souvenirs of Chiang Mai.
Now it is pretty busy from 3 to 6 pm - and uncomfortably so from 6 to 11 pm. Really difficult to take photographs here now.
Many stalls along the main road, and many of the side sois - mostly selling souvenirs and clothes, and offering food and massages. There are also street performers at regular intervals along Tha Pae Road.
Don't forget the Saturday Market at Wua Lai Road either.
