Good place to visit if you have some spare time, but it is a bit artificial. Would suggest to visit some of the other wilderness areas rather.

Pigeon Nest Park is a partially artificial but well appointed area adjacent to the surrounding wetlands. It seems to serve well to corral humanity into a controlled area thereby preventing us from tramping all over the wetlands proper. A great idea! The park covers a large area and you can easily spend a day walking around it. Part of the tree covered area is filled with artificial birdsong and I'm not sure if it is to attract other birdlife, which it failed to do when we were there, or if it is supposed to add t the general ambience; either way, it's not as annoying as you think it might be! You do need to buy a ticket to get into the park but it's not expensive and you can stay all day you want. The #34 bus will take you from Qinghuangdao station and Yingbin Road out to Beidaihe and the Wetlands for a mere 2 yuan per person. It takes about half an hour.
