Cologne Sightseeing: Dom, Museums, More
Sightseeing in Cologne
Cologne’s fourth-largest-city status shows in how much sits inside its compact center, from the cathedral to the museums to the riverfront that ties them together.
The Cologne Cathedral
Since 1 July 2026, sightseeing entry to Kölner Dom costs €12 for adults, €6 reduced, with worship, private prayer and under-14 visits kept free. The full breakdown is on koelner-dom.de . Climb the south tower for panoramic views at €8 / €4, or book a skip-the-line tower and treasury ticket (€12 / €6 combined) to avoid the queue.
Where the Roman collection went
The Roman-Germanic Museum’s Roncalliplatz building, right next to the Dom, has been closed for structural repairs since 2018 and isn’t due back before 2030. Its mosaics and artifacts showcasing Cologne’s Roman past are on display in the meantime at Belgisches Haus, Cäcilienstraße 46, near Neumarkt.
Hohenzollern Bridge and the Old Town
The Hohenzollernbrücke, covered in love locks, gives a free view of the cathedral and the Rhine. From there it’s a short walk into the Altstadt, with its narrow streets, historic buildings and traditional breweries.
The Chocolate Museum and Museum Ludwig
The Chocolate Museum covers the history of chocolate making with tastings included, at roughly €16.50 to €17.50 depending on the day. Museum Ludwig (€19.80 / €13.50 reduced) holds one of the largest Picasso collections outside Spain plus major Pop Art works.
Getting around
Cologne’s KVB trams, buses and U-Bahn cover the city for €3.50 a single fare or €8.40 a day; the compact center is also easily walkable. A 1-hour Rhine cruise from Frankenwerft offers a different view of the same skyline, at roughly €15 to €18.
Beyond the center
If you have an extra day, the Rheinboulevard in Deutz gives a free view back across the river at the cathedral, especially good in the hour before sunset. Cologne Zoo, at Riehler Straße 173, is open year-round and stays a solid pick if you want a break from museums and churches partway through your visit.
Tips for your visit
Buy the cathedral ticket online ahead of a busy weekend. Try Kölsch at a traditional Brauhaus, served in small 0.2-liter glasses called Stangen, and sample local dishes like Rheinischer Sauerbraten. Comfortable shoes matter more here than in most cities, since the Altstadt’s cobblestones and the distance between Roncalliplatz and the Belgisches Haus both add up over a day.
