Things to do
Cologne stands on the Rhine, and two landmarks define its skyline: the Gothic cathedral beside the main station and the river promenade with its bridges. The centre is compact, the old town and Belgian Quarter can be walked, and trams reach the outer districts.
Cologne Cathedral
Climb the spiral staircase of the cathedral's south tower to the viewing platform, where the Rhine and the whole centre open below. See the interior and the stained glass downstairs, and allow about an hour for the ascent.
Museum Ludwig
Museum Ludwig beside the cathedral holds pop art, surrealism and Russian avant-garde work. Afterwards walk along the Rhine to the Hohenzollernbrücke. Two floors of the collection take about two hours, and there is a café inside.
Kölsch in a brewery
Order a Kölsch in one of the historic breweries of the old town, such as Früh am Dom or Brauhaus Sion. Waiters carry small glasses and mark each one on your coaster.
Where to stay
Altstadt
The old town works for a first visit: cathedral, promenade and breweries are close. It is busy with tourists, and evenings get loud around the Alter Markt. You can spend a whole day here without leaving the quarter.
Belgian Quarter
The Belgian Quarter draws people for cafés, small shops and quiet streets. The centre is about twenty minutes on foot, and evenings here are calmer. There are more cafés here and fewer tourists than by the cathedral.
Deutz
Deutz sits on the right bank and gives a view back to the cathedral and the old town. It suits trade-fair visitors at Koelnmesse, though there is little life in the evening.
Getting to and around Cologne
Cologne/Bonn Airport lies fifteen kilometres south-east of the centre; S-Bahn lines S13 and S19 reach the Hauptbahnhof in about fifteen minutes. Trams and the U-Bahn run through the city, and the centre is walkable. The Hohenzollernbrücke links the cathedral with Deutz and is the easy way across the Rhine. From the station it is a short walk across the square to the cathedral.
Three days in Cologne
Cathedral and old town
Start at Cologne Cathedral with the climb up the tower, then walk into the old town to the Alter Markt. In the afternoon go down to the Rhine promenade and cross the Hohenzollernbrücke.
Museums and chocolate
See Museum Ludwig and the Römisch-Germanisches Museum in the morning, then ride to the Schokoladenmuseum. Come back along the promenade and end the day in a brewery. From the museums follow the promenade to the bridge and back to the centre.
Belgian Quarter and Brühl
Walk through the Belgian Quarter over breakfast and look into the market. Then take the train to Brühl for the Augustusburg palace, a UNESCO site. The palace and park take half a day, and trains back run often.
