Just to report back, I went at 6am and there were monks passing by. The were usually alone or two at a time. There are people giving alms to the monks and the monks will give blessings in return. It is not exactly a ceremony with lots of people in attendance, merely an authentic local custom. On the way to Doi Suthep after that, we saw lots of monks and alms giving near to Chiang Mai University.

To see the actual monument is free. But for the other I don’t know. I suggest you do a google search. 😊
