We stayed four nights at Hagerhof, as part of a broader two-week European vacation with our two sons (age 12 and 8). We also rented an apartment in Amsterdam and stayed at a hotel in Vienna. The Hagerhof was definitely the favorite! We loved visiting the animals throughout the day (visiting the cows during feeding at morning and evening, collecting eggs from the chicken coop, holding the guinea pigs and hanging out with the rabbits.) We also rode around on the 4-wheel bikes, and my kids jumped on the trampoline. It was a very peaceful place -- aside from the noises and smells you would expect from a farm -- roosters, tractors, whiffs of manure and barley.
This is a part of Germany that doesn't get a lot of American tourists. Most of the restaurant menus are not translated into English, so if you don't have someone in your group who knows some basic German, you might end up ordering organ meats! Everyone is friendly, helpful and kind.
We had planned to go back into Munich (from where we came by train and rented our car -- you must have a car out here!), but the boys had so much fun at the farm! We also went to Chiemsee -- about 15 minutes away -- and took the ferry to one of the islands to see Ludwig's palace, and rented a little boat. We loved this whole area!
