Although the old city of Wiang Kao in Nan may not cover a large area, experiencing all its attractions can be quite challenging. For those who are visiting for the first time, spending too much time driving around might limit their opportunity to see more places. To cater to tourists interested in exploring the city of Nan, the Nan Municipality has provided a tram service that runs around the old town, complete with a tour guide who explains the sights along the route.
