It is amazing that the long coast line of China does not have much to offer when it comes to natural beauty. There is a bit around Hainan, and a few small corners on the way. The rest is pretty unattractive, man-made and mostly covered with trash. I am currently close the Yellow Sea, and as the name already indicates, it is not a blue ocean. The color comes from the load of silt coming from the rivers. But that is not what is disturbing. The coast line is a completely artificial one, with fish farming behind the land reclamation areas - biologically degraded, polluted and overused. China has the policy, to develop first and clean up later. But what has been done here to the coastal ecology is irreversible. I am sure, you don't want to go there without professional purpose, but still you can download the route I took by clicking here (GPX-format).
