Public Transport: Excellent integrated system of U-Bahn (subway), S-Bahn (commuter rail), trams, and buses. Single tickets cost €2.90-€3.60; day passes (€9.50) and city cards offering unlimited transport plus museum discounts are excellent value. Pick up maps at Hauptbahnhof (main station).
Walking: Old Town is compact and pedestrian-friendly despite cobblestones. Most attractions within 20 minutes on foot. Comfortable shoes essential.
Cycling: Extensive bike lanes throughout the city. Rental shops offer daily rates (€10-15). Rhine cycling paths are flat and scenic.
Taxis: Available but expensive. Apps like MyTaxi offer ride-hailing at comparable rates to traditional taxis.
Trains: Regional trains connect to Bonn (25 min), Rhine Valley castles, and surrounding areas. Deutsche Bahn offers flexible passes for multi-day exploration.
