The Tiergarten might be Berlin’s most famous park, but the sprawling, 7,400-acre Grunewald wins the prize for the city’s most impressive forest. Fringed by the Havel River to the west, it contains a multitude of pleasant hiking and cycling paths, lakes and sand dunes, and a surprising number of cultural, historical, and architectural sights as well. Besides the Teufelsberg man-made hill and adjacent Teufelssee Lake, there are great forest views from the Grunewaldturm, which also has a beer garden. Jagdschloss Grunewald, a 16th-century hunting lodge, has a café and a collection of old masters paintings. Close to the S-Bahn you can see a touching memorial to the deportation of the city's Jews, who were sent from this station to death camps during World War II.
