South of Sachsenhausen, past the stadium and the allotment gardens, the city runs out of things to say. The oak and beech close over the road. The temperature drops two degrees. The noise stops. What begins there is 4,800 hectares of urban forest, one of the largest in Europe, and most of the people who visit Frankfurt never reach it.
The Stadtwald does not advertise itself. No famous view, no single landmark, no reason to appear on the itinerary. What it has is forest: old, mixed, dense, crossed by hundreds of kilometres of paths and tracks and the particular quality of quiet that cities spend considerable effort trying to manufacture elsewhere. Frankfurters know about it. On Sunday mornings the paths fill with runners, cyclists, families with dogs, older people walking at their own pace. The city has been managing this forest since the 14th century. It is, in the most literal sense, a public possession of long standing.
What the forest contains
In October the beech trees turn a colour that sits somewhere between copper and deep gold, and the light through the canopy on a clear morning has the quality of something that cannot be adequately photographed. You need to be standing in it. The photograph on this page was taken in late October, on a path that leads southwest from the Waldlust tram stop through the old oak sections of the forest. This is the route to take if you are coming for the first time.
The Goetheturm stands in the northern part of the forest: a 43-metre timber observation tower that was burned down by arsonists in 2017 and subsequently rebuilt to the original design. From the top on a clear day the skyline is visible to the north and the forest extends south toward the horizon, and the two things together produce one of those images of Frankfurt that makes the city's particular strangeness visible. Financial centre and forest city, twenty minutes apart by tram.
Take the U3 to Waldlust or Hainer Weg, both at the forest edge. By bike, the Main riverbank cycle path runs south from the city and connects directly. From the Römerberg by bike is about 25 minutes, mostly along the river with very little traffic.
On keeping things
Maya Göpel has written at length about how societies demonstrate their actual priorities not through what they say they value but through what they preserve across generations, what they protect from development, what they fund without requiring it to justify itself economically. The Stadtwald is not a park that was created as an amenity. It is a forest that was kept. Frankfurt decided, repeatedly, over seven centuries, to keep it. That decision absorbed pressure in every decade when the land could have been used for something else. The difference between a city that keeps its forest and one that does not is not just ecological. It is a statement about what a city thinks it is for.
What to do
Walk the loop from Waldlust station southwest through the old oaks, around the Stadtwaldweiher lake and back along the eastern path. About 6 kilometres, mostly flat, nothing difficult. The lake is open for swimming in summer. The forest café near the Goetheturm serves coffee and cake and not much else, which is all that is needed. In October, on this route, the colour is exceptional. Bring something to eat for after.
October for colour. April and May for bluebells and the particular green of early beech leaves. Summer weekends near the lake get busy; go a kilometre deeper and solitude is easy to find. Winter mornings with frost on the ground are underrated, particularly the hour after sunrise when the low light comes through bare branches.
