Frankfurt Central Station is only a few hundred metres away from Messe Frankfurt. With the underground line 4 (U-Bahn, in the direction of Bockenheimer Warte), it is one stop until Festhalle/Messe, where you will find the entrance to the exhibition: LEA – Ludwig Erhard Anlage. In addition, you can switch to a tram or taxi once you arrive at the Central Station. If you prefer to walk, this should take around 10 minutes.
