These are very different cities in Northern Thailand. Some of the contrasts can be seen here.
We stayed just inside the old city, separated by a moat and renovated ruins of the walls.
Wat Phrathat Doi Suthep
This famous temple resides in the foothills overlooking Chiang Mai about a 40 minute drive in share taxi. Normally, I avoid photos of visitors to temples. Rather than try to get pristine photographs of the main chedi in Doi Suthep, I entertained myself trying to get photos of selfies and group photos. I especially like the monk.
Not so densely packed with famous temples, but its smaller size made it easy to navigate.
