You can find many charming and interesting places close to Hamburg to pass a few relaxing days before or after the conference.
In just one hour and forty minutes the Intercity Express (ICE) takes you from Hamburg to Berlin, capital of Germany, historical and ever-changing city which is well worth a visit. For further information see http://www.visitberlin.de/en
You can reach Bremen in less than an hour by car or train. Bremen’s historical city center boasts a wealth of attractions: from its listed town hall to its medieval ‘Schnoor’ quarter, the city continues to attract thousands of visitors each year.
The Brick Gothic architecture of Lübeck was declared a World Cultural Heritage Site in 1987 by the UNESCO. The water-enclosed Old Town with its roughly 1,800 listed buildings, historical alleyways and criss-crossed lanes is not, however, just pretty to the eye, but is also the hub of an extremely lively, major city with around 214,000 inhabitants.
The small Hanseatic ‘Saltcity’ Lüneburg can be reached within 20 minutes by train. The historic town center is surrounded by the beautiful landscapes of the Lüneburg Heath and the ‘Elbtalaue’ (Elbe river floodplain).
On the coast of the North Sea or the Baltic Sea you can relax at the beach in places like St. Peter-Ording (North Sea) and the Timmendorfer Strand (Baltic Sea). Or maybe you prefer a trip to one of the famous islands Sylt and Helgoland. You can reach both very easily from Hamburg, Sylt by train (you can even take your car on the train) and Helgoland by boat directly from the ‘Landungsbrücken’ (jetties).
