A great diversion for those traveling with kids is Monkey Mountain, or Affenberg Zoo (Affenberg Landskron). 

Located just a few minutes' drive outside Villach, this fun family attraction can be enjoyed as part of an informative guided tour, led by experts, on the care of these fascinating creatures. 

All told, the zoo is home to some 164 Japanese macaques, each of them free to roam around their huge, tree-lined enclosures, and to interact with visitors. In addition to seeing these gentle animals up close, you'll also see them raising their babies, as well as swimming and diving (weather permitting).
