Known as Northern Germany’s center for business, tourism, and culture, Hamburg is filled with possibility. Explore the world’s largest model train exhibit at Miniatur Wunderland or hop on a boat tour in lively Hamburg Harbour. Head to Speicherstadt, a UNESCO World Heritage Site of warehouses built on oak poles from 1885 to 1927, and traverse the Alter Elbtunnel—a work of German engineering opened in 1911 which goes under the Elbe River. The city is known for its delicious fresh seafood, so stop by the Hamburg Fish Market for an unforgettable bite. Attend the blind awareness–raising exhibition Dialogue in the Dark, stroll through the beautiful botanical gardens in Planten un Blomen Park, and see an unforgettable revue at Schmidt's Tivoli. If you’re here with kids, check more than 1,800 animals at the Hagenbeck Zoo, visit Heide Park for thrilling roller coasters and other action-packed rides, or create your own chocolate bar at Chocoversum.
