Day 1 — Cologne: Rheinauhafen + Chocolate Museum
🍫 Cologne Chocolate Museum — a bright start for kids: a mini factory, a warm chocolate fountain, interactive stations, and a view of the Rhine. After the museum, take a walk along the Rheinauhafen waterfront among the “crane houses,” with big steps by the water, scooters/balance bikes, and ice cream. The after-travel formula: 1 big впечатление + free outdoor play.
