At over 640 hectares, Europe's largest city forest, beginning about 1km northeast of the Hauptbahnhof, is also known as Hanover's grüne Lunge (green lung). It is well frequented and loved by locals who picnic, play and cycle through the enchanting woods, luminous green in the summertime, where it's easy to imagine you're not in the middle of a city of half a million people.
Bus 100 going north to Emmichplatz stops at the entrance arch.
