Day 1 — Altstadt: Town Hall, Burgplatz and the Rhine promenade
🚶 Start at the Town Hall Square (Marktplatz) and Burgplatz by the Schlossturm: stone, water, and history come together in a single frame here. Head down to the Rheinuferpromenade—a wide riverside promenade with a river breeze, street musicians, and endless views of the bridges. In Altstadt’s narrow lanes, drop into classic breweries (Altbier is from here) and browse the windows of artisan shops. Finish with sunset by the water: the Rhine is especially meditative at this hour.
