All buses pull into the west side of the city at the Zentraler Omnibusbahnof (ZOB). The Messe Nord S-Bahn station is a bit of a walk, so catch bus M49 from the Messedamm/ZOB bus stop directly to S/U-Bahn station Zoologischer Bahnhof. (Picture: © Von Fridolin freudenfett - Eigenes Werk, CC BY-SA 3.0)
