Did you know that a tiny bit of the Camino de Santiago exists between two Madrid metro stations?
Following the train tracks (and veering off them every now and again) reveals the industrial past of the Jarama Valley: current and disused railway infrastructure, an old fly-tipping zone (with a warning sign in pesetas!), bunkers and abandoned agricultural buildings. Dipping into Arganda, you can also visit a tiny barrio of only casas bajas with traditional door curtains and, of course, lots of storks.
