Altona station is the useful rail starting point; Rathaus Altona is the nearby bus-stop name listed by tourism. From the station, use the town-hall/Elbe direction and public crossings to reach the upper park. Include that approach again when allowing time for your train home.
Arrival update, checked 15 October 2026: Elbchaussee roadworks are expected to continue in the eastern section until December 2026. A full vehicle closure between Hohenzollernring and Elbchaussee 20 is scheduled from 09:00 on 19 October to 17:00 on 21 October. Work from number 20 towards Kaistraße/Palmaille is planned for November, with exact dates to follow. Weather can change the schedule. These are road notices; they do not announce a closure of Altonaer Balkon. Check hvv and the signs for your actual approach, particularly if arriving from the west or extending the walk.
