Amsterdam has a sprinkling of these mini-farms, complete with goats, usually a pig and some oversized rabbits. The nicest location - with a traditional farmhouse - is at the far side of Westerpark.
Out in the Amsterdamse Bos (woods) is the goat farm - a staple Sunday excursion for Amsterdam families with smaller children. You can buy little bottles of milk to feed the kids, and then eat goat's milk ice-cream (all organic of course).
