Cologne

The best time to visit Cologne is during the shoulder seasons, specifically from April to May and September to October. The weather is pleasant, crowds are smaller than in summer, and you can enjoy events like the Cologne Spring Festival or the Rhine in Flames fireworks display.

Top attractions in Cologne include the Cologne Cathedral (Kölner Dom), the Roman-Germanic Museum, the Chocolate Museum, the Great St. Martin Church, and the colorful houses along the Rhine River. Don't miss a stroll through the Old Town (Altstadt) and a visit to the Hohenzollern Bridge.

Cologne is known for its friendly and open culture. Be aware that 'Kölsch' beer is a local specialty and is served in small glasses, and waiters will keep bringing you a new one until you put a coaster on top of your glass. Also, 'Kölle Alaaf!' is the traditional carnival greeting, used during the Karneval season.

Cologne has an excellent public transportation system, including trams (Straßenbahn), buses, and S-Bahn trains. The city center is also very walkable. Consider purchasing a day ticket or a multi-day travel pass for convenient and cost-effective travel.

You should definitely try 'Halve Hahn' (rye bread with cheese), 'Rheinischer Sauerbraten' (marinated roast beef), and 'Himmel un Ääd' (black pudding with mashed potatoes and applesauce). Enjoy these dishes at a traditional 'Brauhaus' (brewery) while sipping on Kölsch beer.
