Are there many people going to Pigeon Nest Park during the Dragon Boat Festival?

There will definitely be more, because the only places in the northeast where you can see the sea are Beidaihe and Dalian, so resources are scarce, and there are more people every year. I hope to help you. Welcome to click "Accept"

Of course more. At this time, it is not possible to go swimming in the sea, and people will naturally concentrate on the scenic spots. There isn't even a place to park on the side of the road.
