The Sanjiangkou Wetland is located in Ningjiang District, 40 kilometers away from downtown. It is accessible by ship from the Songyuan wharf. It covers an area of 30 million square meters. It got its name from the fact that the Nenjiang River, the West Songhua River and the East Songhua River converge right here. The water quality differences make the converged flow in two different colors, like the green dragon and the yellow dragon riding and rolling together to create a truly spectacular scene. Standing on the fairway, you will see the meandering Nenjiang River rolling from northwest, and the West Songhua River and the East Songhua River from southeast after merging.
