Hadsund Dyrehave is a small "dyrehave" (Danish equivalent of the British deer gardens, the word literally meaning "deer garden") in the middle of the small town Hadsund.
The main area (pictured here) is a huge walkthrough exhibit (though smaller than in many deer gardens where the deer live in semi-liberty) for a big group of sika deer and a few fallow deer. There's also a medium-sized petting exhibit for African pygmy goats.
It's technically a zoological institution, though I didn't think it deserved a folder of its own, having only two exhibits and three species.
