Cologne offers excellent transportation, making it easy and efficient to explore the city. The well-connected public transit system includes trams, buses, and trains, with the central station (Köln Hauptbahnhof) just steps from the famous cathedral. You can also enjoy walking or biking through the compact city center. Cologne is generally very safe, even at night, though it’s wise to stay alert in crowded areas. Keep valuables secure, especially during festivals, and always carry a copy of your ID or passport.
