I caught the Hochbahn out from the station to the Landungsbrücken and from there went on a very pleasant ferry ride (ignoring the Hail storm partway through) along the Elbe to Finkenwerde and then onto Blankenese.
I caught the S-Bahn back into Hamburg and then went for a wander through the Elbe tunnel to the opposite bank of the river before it was time to head back to the Hauptbahnhof, pick up my luggage and head for the airport and the flight home.
