Below, we'll go through each place in order, with photos, hours, and directions.

1. Cologne Cathedral

Cologne Cathedral at night in festive lighting

Cologne Cathedral is visible from anywhere in the city center. Its two towers rise nearly 160 meters, and until the late 19th century the church remained the tallest building in the world (as of 09/2026, official website).

Construction began back in the Middle Ages and was only completed several centuries later. The long interruptions left their mark on the building: the Gothic framework never fully acquired its lavish decoration. But the cathedral retained an authenticity that many later-completed churches lack.

Inside, the cathedral functions as a museum. You'll see medieval stained glass, sculptures on the columns, and the famous treasury with reliquaries. The Shrine of the Three Kings deserves special attention: pilgrims from all over Europe come here for it.

From July 1, 2026, a ticket is required to enter; free admission has been discontinued (verified 14.09.2026 on the ticketing site). Climbing the tower is paid separately, and it's more than 500 steps with no elevator. The line for the viewing platform is shorter in the morning.

How to get there: Dom/Hauptbahnhof station, exit toward the cathedral.
Tickets and hours: the cathedral is open daily from 6:00 to 20:00; tickets for the cathedral, the tower, and the treasury are purchased separately (as of 09/2026, official website).
Who it's for: those who want to see the city's main symbol and climb above the Rhine.
Not for: those who struggle with stairs and no elevator.
The catch: in high season, climbing the tower takes over an hour.

Tours of the cathedral and Old Town are easy to book in advance: Cologne tours on GetYourGuide.

2. Fragrance Museum

Illuminated facade of the Farina House in the evening in Cologne

The Fragrance Museum operates in the house of Johann Maria Farina, who was the first to blend floral scents and called the mixture "Cologne water." The Farina factory is considered the oldest perfume house in the world, and production still continues here today.

The workshops have been preserved in the house and turned into a museum. A guide in period costume leads the tour, showing you copper stills, antique bottles, and walking you through the entire process. At the end, you can smell the cologne and buy a bottle in the shop.

The original scent is citrusy, with bergamot and herbs. Farina himself said his water smelled like a spring morning in Italy after rain. This is where the word "eau de cologne" comes from, which the French translated as "Cologne water."

How to get there: metro to Neumarkt station or bus 132.
Cost: admission is paid, tours run on a schedule.
Who it's for: fans of perfume history and unusual museums.
The catch: on weekends, groups fill up quickly, so it's best to arrive at opening time.

3. Museum Ludwig

Aerial view of Museum Ludwig and Cologne Cathedral

Museum Ludwig holds one of the best collections of 20th-century art in Europe. Here you'll see avant-garde, pop art, expressionism, and surrealism, as well as one of the largest collections of Picasso in Germany (as of 09/2026, official website).

The gallery's foundation was laid by the Ludwig couple: in 1976, they donated around 350 works to the city and paid for a new building next to the cathedral (as of 09/2026, Museum Ludwig website). This gift is what led to a modern museum appearing in the center of Cologne.

The new building looks striking against the Gothic backdrop. Its windows offer an unexpected view of the cathedral, so photography is allowed here and even convenient. 20th-century art is presented without fuss, there are many rooms, and you won't feel tired after a couple of hours.

How to get there: trams 5, 16, 18 to Dom/Hauptbahnhof stop.
Cost: admission is paid, the museum is closed on Mondays.
Who it's for: those interested in modern art and Picasso.
The catch: complex exhibitions are hard to understand without an audio guide.

4. Chocolate Museum

Chocolate museum building with signage on the facade

The city's sweetest museum stands on an island in the Rhine, and its building resembles a huge ship. Inside, a real chocolate factory operates, visible through glass (as of 09/2026, official website).

You'll follow the entire journey of the cocoa bean, from plantations to the finished bar. Large machines mix, temper, and wrap the chocolate, with only souvenirs packed by hand. A separate exhibit is dedicated to vintage boxes and labels from chocolate brands.

Children love the chocolate fountain, about three meters tall, most of all. Wafers are dipped into it and handed out to visitors. At the museum, you can order your own custom bar made to your recipe, and the shop sells chocolate from well-known brands.

How to get there: buses 106, 132, and 133 to Schokoladenmuseum stop.
Cost: admission is paid, and with the KölnCard on GetYourGuide you get museums and transport on one card.
Who it's for: families with children and anyone with a sweet tooth.
The catch: during school holidays, a line forms at the ticket office, so it's best to buy tickets online.

5. Town Hall Square

Town Hall Square lies in the center of the Old Town, three hundred meters from the cathedral.

Underground, at a depth of about ten meters, there is an archaeological museum. It displays the remains of a Roman settlement and tells the story of how medieval Cologne lived. The exhibition takes you back several centuries.

City festivals and fairs take place on the square, and the town hall itself hosts receptions and balls. During the day it is noisy here, but everything is close to the cathedral.

How to get there: metro to Dom/Hauptbahnhof and Heumarkt stations or bus 132.
Cost: the square and viewing from outside are free, the museum in the basement is paid.

The catch: during the day the square is noisy and crowded.

6. Phantasialand Park

Mexico area with waterfall at Phantasialand

Phantasialand Park is located in Brühl, half an hour from Cologne. It is not just rides, but a themed town divided into zones representing different countries.

There are water slides, carousels for toddlers, and extreme swings with a loop. For those who get wet, there is a warm-air dryer. Chinese acrobats perform in the park, and "living" dolls and cartoon characters stroll along the paths.

In summer the park stays open longer, in winter it closes earlier, so check the opening hours before your trip.

Cost: admission is paid, the ticket covers most rides.
Who it's for: families with children and thrill-seekers.
The catch: on weekends the lines for popular rides are long.

7. St. Martin's Church

Church interior with a large candelabra and candles

Great St. Martin stands on the banks of the Rhine next to the cathedral. Of the city's twelve Romanesque churches, this one is considered the most beautiful, and Fischmarkt Square offers the best view of its four towers.

The church has survived destruction and rebuilding but has kept its Romanesque appearance. The altar was built in the shape of a clover leaf, the vault of the main hall has ten sides, and the tall windows are decorated with stained glass depicting saints.

Inside there is a fragment of an ancient Roman column, which locals consider a talisman for the city. Go in at a quiet time to see the frescoes without the crowds. Remember that this is an active church, so dress modestly.

How to get there: metro to Rathaus or Heumarkt stations, then walk toward the Rhine.
Cost: admission is free, but your appearance should be appropriate.

8. Church of the Holy Apostles

East facade of the Church of the Holy Apostles

The Church of the Holy Apostles stands on Neumarkt Square, in the very heart of the Old Town. It is the third-tallest Romanesque church in Cologne, with two towers on either side.

Inside you will find gray-blue frescoes of St. John, colorful stained glass, and a huge organ. The sculpture of the twelve apostles and the ancient baptismal font are considered the church's main treasures. The interior has been restored several times after wars, but the frescoes have survived almost untouched.

You step in from the noisy square and find yourself in silence. This is one of those churches where it is easy to take a break in the middle of a walk.

How to get there: trams 1, 7, 9, 11, and 14 to Neumarkt stop, buses 134 and 146.
Cost: admission is free, photography is allowed.

The catch: on Tuesdays the church is closed to tourists.

9. Ethnological Museum

Modern brick building of the Rautenstrauch-Joest Museum

The Rautenstrauch-Joest Ethnological Museum is one of the five largest in Germany. It explores how different peoples explain the world and why their customs are so different.

In the halls you will see old photographs, ritual objects, rare journals, and monographs. The exhibitions tackle difficult topics: life and death, rites, relations between men and women, and the mistakes of generations that people repeat for centuries.

A separate exhibition is dedicated to childhood, feelings, and the problems of a child. Temporary projects are also held here, so it is worth checking the museum's website before visiting.

How to get there: metro to Neumarkt station.
Cost: admission is paid, and there are noticeably fewer people in the morning.
Who it's for: those who enjoy unhurried, substantive exhibitions.
The catch: some texts are only in German, without translation.

10. Heinzelmännchen Fountain

Cologne Cathedral and Hohenzollern Bridge over the Rhine

Not far from the cathedral hides the city's most famous fountain. It is a monument to female curiosity: in the center stands a woman with a lantern, and next to her gnomes are scattered along the stairs.

The sculpture was created by the Renard father and son, based on a poem by a German poet. According to legend, a woman scattered peas for the gnomes to catch a glimpse of how they helped the city at night. The offended gnomes supposedly left Cologne forever.

Around the fountain there are bas-reliefs with other characters from the poem, greenery, and flower beds. Tourists spend a long time looking for this sculpture, so it is almost always surrounded by people.

How to get there: on foot from the cathedral, look for the street between the cathedral and the Rhine.
Cost: viewing from outside is free.
Who it's for: those who love urban legends and small sculptures.
The catch: the fountain is small, easy to walk past.

11. Cologne Zoo

Aerial view of Cologne with the Rhine River and the city

Cologne Zoo in the north of the city is considered one of the oldest in Germany. It occupies a large area next to the Botanical Garden, and it is home to elephants, camels, and baboons (as of 09/2026, official website).

Monkeys live in a purpose-built "Jungle House," and tropical plants are kept in rooms with a special climate. The aquarium with bright fish, mollusks, and reptiles is particularly impressive.

The grounds are clean and well maintained, and the animals are fed on a schedule. Tickets are cheaper to buy online in advance; in summer there is a line at the ticket office (checked on 14.09.2026 on the official website). From the cathedral and back you can take a special "Zoo Express."

How to get there: tram 18 or bus 140 to the Zoo/Flora stop.
Cost: admission is paid, and an online ticket also works as a transit pass for the zone (as of 09/2026, prices on the zoo's website).
Who it's for: families with children and animal lovers.
The catch: some enclosures are far from the entrance, so plan at least half a day.

Zoo tickets are convenient to buy in advance: tickets on Tiqets.

12. Cologne City Hall

Cologne City Hall with tower and arched facade

Cologne City Hall is considered the oldest in Germany. It stands in the historic center between the Old Market and Town Hall Square, just three hundred meters from the cathedral.

The building was constructed in several stages, and the process stretched across the 14th to 16th centuries. The combination of Gothic and Baroque gives the city hall a picturesque look. On the facade you'll find a wooden face named Platz-Jabbek: with every strike of the clock it opens its mouth and sticks out its tongue. The tower is decorated with figures of notable citizens.

The city hall at Rathausplatz is open for tours on weekdays; the rest of the time the building is occupied by the city administration.

How to get there: metro to Dom/Hauptbahnhof and Heumarkt stations, bus 132.

Snow-white walls, old stonework, and a picturesque pond create a harmonious ensemble, complemented by Gothic turrets. Two arched bridges connect the castle to a large, shady park.

Today, Weisshaus is privately owned, so you can't go inside. You can get there by taking the Stadtbahn toward Bonn and getting off at the Arnulfstraße stop.

The gate was built back in the early 13th century as a demonstration of the power of Cologne's fortifications. Later it housed a prison and a horse tram depot, and at the end of the 19th century a history museum opened here.

Napoleon and his wife entered the city through this gate. After the city wall was demolished, the authorities decided to preserve the gate, and at the end of the 19th century the architect Stübben carried out a reconstruction. Later it housed a natural history museum and a branch of the history museum.

The cable car takes you over the Rhine near the zoo, and from here you get the best view of the river, the Old Town, and Cologne Cathedral from above.

The cable car opened in the mid-20th century and became the first of its kind in Germany. It held the status of the only one in the country for several decades, until similar transport appeared in Koblenz.

The cable car runs from April to October, daily from morning to evening, with cabins traveling between Rheinpark and the zoo. This way you can combine both outings in one day and see the city from above.

The bridge opened in the early 20th century, and today it is one of the most popular photo spots. Thousands of couples have left padlocks on its railings, which is why the bridge is also called the lovers' bridge.

Access to the bridge is free, and it offers an excellent view of the cathedral and the river. Go at sunset, when the city is lit up.

The Roman Tower was built in the 2nd to 3rd centuries, when Cologne was considered a remote outpost of Rome. The walls are made of sandstone, limestone, and trachyte and are decorated with authentic mosaic masonry.

After the Romans left, the city was surrounded by a fortress wall, and the tower served at various times as the Monastery of St. Clare and as a residential building. It became a historical monument in the late 19th century, when it was restored and given neo-Gothic features.

⁉️🤔 Frequently asked questions

How many days do you need in Cologne?

Cologne's main sights can be covered on foot in one day. Half a day is enough for the cathedral, Rathausplatz, and the Old Town; save the other half for museums. If you want to add the zoo, the cable car, and Brühl, plan two days and take your time.

What can you see in Cologne for free?

Great St. Martin, the Church of the Holy Apostles, the Church of St. Pantaleon, Flora Botanical Garden, and the Roman Tower are open free of charge. Walking across the Hohenzollern Bridge is also free.

When is the best time to visit Cologne?

Plan your trip for May, June, or September. In summer the center is crowded with tourists, and in winter the cable car and some parks close. Carnival in February draws huge crowds, so book accommodation well in advance.

Where to go with kids?

Kids usually enjoy Cologne Zoo with its "Jungle House" and aquarium, as well as the Chocolate Museum with its fountain and waffles. For a full day, you can head to Phantasialand in Brühl. The cable car is also a hit with kids, but it only runs from April to October.

Is the KölnCard worth buying?

If you plan to visit two museums and use public transport, the KölnCard pays for itself. The card covers entry to Cologne museums and city transport. But if you're only walking around free sights, you don't need it. Compare prices in advance and decide based on your itinerary.

All thirty places are easy to view on a map. Mark the cathedral as the center, then move along the Rhine or along the ring of the former city wall. Book trains to Cologne in advance: train tickets to Cologne on Trip.com.

In short: what to book

Cologne is easy to explore on foot: the cathedral, Rathausplatz, and the Old Town are all close together. Plan paid attractions in advance so you don't waste time at the ticket office. Look for accommodation in the center, near Hauptbahnhof.

If you have one day: start with the cathedral, cross the Hohenzollern Bridge, and return to Rathausplatz.
If you have two days: add the Chocolate Museum, the zoo, and the cable car.
If you're traveling with kids: plan for the zoo and Phantasialand in Brühl.
