Duisburg

The best time to visit Duisburg is during the spring (April-May) and summer (June-August) months. The weather is pleasant, allowing for outdoor activities and exploration of the city's parks and attractions. The Christmas market in December is also a popular time to visit.

Key attractions in Duisburg include the Landschaftspark Duisburg-Nord (an industrial heritage park), the Duisburg Zoo, the Küppersmühle Museum (contemporary art), and the Innenhafen (inner harbor) area with its modern architecture and waterfront restaurants.

Duisburg, like other parts of Germany, values punctuality and politeness. It's customary to greet people with a 'Guten Tag' (Good day) or 'Hallo' (Hello). Tipping is common in restaurants (around 10%), and it's considered polite to use 'Bitte' (Please) and 'Danke' (Thank you).

Duisburg has a well-developed public transportation system, including trams, buses, and the U-Bahn (subway). These are efficient ways to get around the city. Walking and cycling are also popular, especially in the city center and along the river. The Duisburg Hauptbahnhof (main train station) provides excellent connections to other German cities and international destinations.

Duisburg offers a diverse culinary scene. You can find traditional German cuisine like sausages, schnitzel, and hearty stews. The city also has a variety of international restaurants, including Turkish, Italian, and Asian options. The Innenhafen area is particularly known for its restaurants and bars with waterfront views.
