The 1200 acre Frankfurt City Forest (Frankfurter Stadtwald) forest is the largest inner-city forest in Germany. Dating back to the 13th century, the Forest covers the southern areas of Schwanheim, Niederrad, Sachsenhausen and Oberrad, as well the northern parts of the Stadtteil Flughafen district. Four nature trails and sport paths cross the Forest. There 1600 seating benches, 25 rest huts, 6 playgrounds, and 9 ponds. The forest is 7 km south of the city.
There are many running opportunities along the 400+ km network of trails, including 157 km of signposted cycling and hiking tracks. Runners World has a suggestion of the following route: Distance: 2 to 20 km. The circuit starts at the Oberschweinstiege, where there is also a car park. From there to Darmstädter Landstraße, over the pedestrian bridge, at a central intersection on the Hainer Weg northward. Via the Babenhauser Landstraße, to the Goetheturm, then on the Kesselbruchschneise as well as the Schillerschneise back. For other routes, best to get a map from the Visitor Center (very little is available online!).
There two main attractions are the Stadtwaldhaus / State Forest House visitors centre in the middle of the forest, and the Goethe Turm / Goethe Tower – a great lookout over the forest and Frankfurt.
