Cologne is one of our favourite German cities. With its magnificent architecture and relaxed vibe, it is one of the best places to visit in Germany. You can easily spend days there and always find new things to do and see. If you only have one day there, then let us show you the five best things to do in Cologne in one day. We have also included another ten alternative ideas for your one day in Cologne.
Understanding Cologne
Cologne was heavily bombed during World War II. With the British Air Force dropping more than 35,000 tons of bombs on Cologne Germany in 262 separate air raids, the city was devastated. 95% of the population was either evacuated or killed, and much of the architecture was destroyed.
At the end of the war when Germany was carved up between the Allies, Cologne benefitted from its proximity to both Düsseldorf and Bonn. The city underwent a huge regeneration, with many of the destroyed Romanesque churches being carefully reconstructed. Today, it is the fourth-largest city in Germany and home to one of Europe’s oldest and largest universities.

City of Contrasts
The destruction of the city has resulted in a mishmash of architecture that is a contrasting mix of old and new.
The most notable landmark is the Dom (cathedral) – the largest gothic church in Northern Europe. Other Cologne sights include the Rathaus (town hall) and the medieval city gates. For us, the imposing Hohenzollernbrücke over the Rhein was one of the best things to see in Cologne!

Although the contrasting architecture is not to everyone’s taste, the city itself has a wonderful vibe that is also made up of contrasts. We found Cologne to be relaxed but lively, peaceful but buzzing, all at the same time. Scroll down to find out how you can spend a perfect day on your Cologne trip.

Start Your Day with a Breakfast at the Fischmarkt and Marvel at Gross St.Martin
The perfect day in Cologne starts with a good coffee. To make your breakfast more memorable, we recommend a coffee at the Fischmarkt (fish market), next to the Rhein River. Whilst there is no longer an actual fish market on the site, it is now an Instagram-worthy and relaxed square. It features colourful buildings, a cute fountain and the impressive Gross St.Martin (Church of Great St. Martin) as a backdrop. Chose one of the many available restaurants and cafes and enjoy your breakfast outside when the weather is good.

Great St. Martin
After your breakfast, you can head directly to the Church of Great St.Martin and marvel at its amazing architecture. This Romanesque Catholic Church was founded in the year 960 on what was then an island in the Rhine River. Especially impressive is its majestic tower! The church was almost completely destroyed in the World War II and was again completely restored in 1985. These days it’s a must-see on every Cologne walking tour.

Visit the Kölner Dom (Cologne Cathedral)
The Cologne Cathedral (officially called “Hohe Domkirche Sankt Petrus”) is definitely THE highlight of every Köln sightseeing trip. The cathedral was declared a UNESCO World Heritage Site in 1996. This Gothic architecture in the heart of Cologne Old Town is the most visited monument in whole Germany. More than 20’000 people visit it daily and regardless how pushed you are for time, it is most important of all the things to do in Cologne Germany

The Cologne Cathedral
Worth the View
To see Cologne Cathedral from the inside is great, but the best thing is definitely to climb the 533 steps and enjoy the amazing view over Cologne. The south tower of the cathedral is approximately 100m high. It might not be an easy climb, but anyone who’s fit enough and loves good views should definitely do it! You can check the official webpage of the Cologne Cathedral for current opening hours and entrance fees.

We loved the great vistas from the south tower!

From here you can see the Great St.Martin church
The best place to catch a photo of the Cologne Cathedral is the huge square on the south side of it. There you can also find the “Früh am Dom”, which brings us to the next activity of our Cologne travel guide.

Have a Kölsch at the Früh Brauhaus
Climbing the tower of the Cologne Cathedral makes you quite hungry and thirsty. This is why your next stops should be to visit another of the highlights of Cologne: The Brauhaus (brewery) Früh am Dom. Früh is a traditional brewery in Cologne and has been around more than 100 years. They produce a special beer, only brewed in Cologne, called Kölsch.

The entrance to the Früh Brauhaus
Kölsch
Kölsch is a light ale with a lovely golden colour and normally comes in cylindrical 0.2l glasses. This seems to be a rather small glass. Be warned though: The waiter will just bring you a new glass as soon as you finished your old one. The traditional way to show that you had enough Kölsch is by putting a beer mat on top of the glass. If you really like German beer, then you should definitely have a look at this awesome Cologne Pub Crawl.

Delicious food and a cold Kölsch, the perfect reward after climbing the tower of the Cologne Cathedral
Of course, you can also get some delicious traditional German food in the Brauhaus Früh am Dom.
Put a Love Lock on the Hohenzollern Bridge
This one is for all the hopeless romantics out there. The Hohenzollern Bridge is probably one of the most famous places in Germany where couples place their love locks. In 2013, a German newspaper took the task of counting all the love locks on this Cologne bridge. In about 30 hours, they counted a total of about 150’000 love locks on the bridge! They also estimated that there are about 10 more locks added every hour. Now I leave it to you to work out how many there might be right at this moment.
No Danger
The “Deutsche Bahn” (German railways) wanted to get rid of all those locks first, but after deciding that they don’t cause any danger to the stability of the bridge, they then decided to leave them where they are.
We loved this fish love lock!

Look at this cute turtle!

Their love for each other must be huge!
The tradition is to engrave the names of the couple, friends or family who visit Cologne on the lovelock, hang it on the Hohenzollern Bridge and then throw the key into the Rhein River.

End Your Day with a View from the Triangle Building at Sunset
Every perfect day should end with a sunset! And if you want to experience the best sunset views in Cologne, then you have to go to the viewing platform of the Cologne Triangle building, on the east side of the Hohenzollern Bridge.

Not the worst view from the Triangle Tower
Taking the lift, you’ll reach the 29th floor of the Cologne Triangle without any effort and in only a few seconds. From a hight of 103 meters, you can enjoy a 360 degree view over the great city of Cologne. You can find here the current opening hours and entrance fees.
