Go for a walk in the City Forest (Stadtwald) in the south of Frankfurt. With about 48 square kilometres, it is regarded as the largest inner-city forest in Germany. Six playgrounds and nine ponds make the forest a popular tourist attraction. The forest can be reached via tram line 14 direction Neu-Isenburg/Stadtgrenze from Frankfurt South Station (Frankfurt Süd). Trams 12, 19, 20 and 21 also connect the Stadtwald with central Frankfurt.
