The pictured area is the (by Danish standards) huge wetlands in Gudenådalen/Vorup Enge just south of Randers.
Randers Naturcenter is a nature center located in the town of Randers, Jutland. It's not really a zoo, but as a nature center it obviously has a major focus on animals and nature, and it has eight species of captive animals (mostly domestics). Beyond the animals, there are some herbal gardens, exhibition houses, classrooms, and a bird hide. The center is free to visit, but it's only open during school hours (except for the bird hide which is always open).
