Until far into the 20th century, Ottensen was an area covered by cobblestone alleys and dominated by small artisanal enterprises in inner courtyards, workers' pubs, and inner-city industries. Now, however, it has become one of Hamburg's liveliest and most popular trend areas. Buildings are still closer together than elsewhere in the city. To the south, the Elbe attracts visitors, and the harbour is not far away. Despite the hustle and bustle, Altona and Ottensen have remained livable and friendly - even and especially for families. And many an old inner courtyard workshop has been resettled by young upcycling designers who bring ideas and products for sustainable living. On this walk you will discover everything that will make your green heart pound - organic coffee at Torrefaktum Kaffeerösterei, organic herbal teas and natural cosmetics at Grün & Schön, upcycled furniture made out of old drawers at Entwurf Direkt Store. The green meadows at Altonaer Balkon or Volkspark Altona offer the perfect place to relax after your tour.
