It is said that hotels in Beidaihe are quite expensive now, probably above 200 yuan. It will be cheaper to come to Qinhuangdao, but you can't play at night.
The scenic spots you can enjoy include Tiger Stone Park, Lianfeng Mountain Park, Pigeon Nest, Olympic Avenue Park (there is a musical fountain at 9 pm, which is very nice and you can watch water movies), and you can also go to the strange building if you are brave. It's good to keep you in a cage for the tigers to see, but if you are unlucky, the tigers won't like to see you and stay in their nests. ...
The night view of Beidaihe is beautiful, and all kinds of buildings are brightly lit, including European classical style, Chinese classical style and other different styles of buildings, which are pleasing to the eye.
That's about it.
I hope you have a good time!
