It's very sunny, so go early to avoid the crowds and sun. The journey from Jinlong Bridge to the old wharf, involving 9 dams, is too long and unnecessary. The whole trip takes about 1.6 hours, and the dam rushing isn't as exciting as you might imagine. So, try a shorter 4-dam trip, which takes about an hour. There are also many round-trip options available, making it convenient for self-driving tours.
