A walk through the Driehoek, heading for the large De Zeearend observation hut. From there, you have a clear view of the Oostvaardersplassen. The Driehoek is a former willow copse with grazers. The willows are dying off due to old age and disease and grazing. This means more light reaches the soil, and new bushes start growing. This is clearly evident during the walk. If you look closely, you will see different birds. And you might even encounter a herd of grazers to admire from a distance.
