This isn't Northern Europe, it's the Rongcheng Swan National Nature Reserve in Shandong.

There are several places to see swans in Rongcheng, but this place has a pristine environment. The sunrise in the morning, accompanied by the arrival of the swans, is simply a blockbuster life experience. (See the video on the homepage) Navigate to Honghu Photography Base, and it is recommended to arrive before 5:30 am in winter. Facing east, as the sun peeks over the horizon, swans arrive one after another—two, three, a group... In less than half an hour, thousands of swans gather on the ice. Note: Sunrise in winter is approximately between 5:40 and 6:00 am. Remember to check the time before you go.
