The southern section of Nanjing, where we stayed, has a series of neat canals that all converge upon a crowded pedestrian street. Each night we took a walk through the brightly lit streets. Once we splurged and took a boat tour of the canals.
The boat tour was about an hour long, and it took us through a number of lighted scenes on the side of the river. It felt a lot like the drive through the Minnesota Zoo or Lake Phalen during Christmas, but with a Chinese theme of course. We started at dusk, and ended in full night.
The only issues we had with the boat tour was that it was a covered boat with windows, which made it actually hot inside the boat. Also the way the seats were arranged made it difficult to see well comfortably.
