Amsterdam's largest green areas are on the edge of town. The Amsterdamse Bos is easy to find, with boating lakes, an open-air theater and large playground. While nature lovers may enjoy a beautiful walk through the woods, plane spotters can watch low-flying aircraft coming from Schiphol. The Amsterdamse Bos is also where you'll find the Bos Museum, which has maps of the park, including walking routes and Geitenhouderij Ridammerhoeve, a goat farm with 120 goats and loads of adorable kids. It also sells bio-dynamic goat's milk, cheeses and ice-cream, and has a small recreation area and sandpit.
