Tripadvisor says this is the top thing to do in Ganzhou, but I guess it's a matter of opiniin. Still, if you're visiting Ganzhou, be sure to go to the pontoon. I walked across the pontoon and took pictures along the way. At the other end was a small village, part of which I also explored. Back on the side where it starts is a refurbished section of the old (Song Dynasty) city wall, which is another must-see.

This is one of two pontoon bridges in Ganzhou. The two rivers Gong and Zhang come together in Ganzhou to form the Gan River. One pontoon bridge spans each of these two tributaries near the point where they meet. You can walk across the pontoon bridge, which is just long wooden planks fastened together, sitting atop about 60 floating wooden boats. Really interesting!
