In fact, koeien in de wei is such a well-known phenomenon in the Netherlands that it has become a tourist attraction. Farmers announce the date that their cows are set to be let out so that people can travel from far and wide to enjoy the spectacle. These events often take place over a weekend in April.
Visitors travel to farms across the country to witness koeien in de wei. According to CowSignals, 65 percent of Dutch cattle will graze during the summer. But it’s the way the animals behave when they are released from their shelters that has captured the public imagination, not to mention the attention of the media.
In April 2015, CowSignals posted a video on YouTube that captured koeien in de wei on one Netherlands farm. Before the herd is let loose, a crowd of visitors gather around to witness the event. And they are amazed by the animals’ response to the outdoors.
