Cologne 6 Days: Built Around Day Trips

Six days is enough to base in Cologne and take five real day trips without repeating a train route. Day 1 sets up the city; Days 2 through 6 send you to Bruhl, Bonn, Dusseldorf, Aachen, and the Ruhr, each reachable on a single regional train. Have a seventh day? The 7 day version adds the Romantic Rhine. Tighter on time? See the 5 day , 4 day , and 3 day versions, or the day trip guide for the full comparison.
Book these before you go:
- Cologne hotel near the Hauptbahnhof, book early if any night falls near Karneval or a football weekend: check rates on Booking.com
- Aachen’s throne room guided tour, the only English slot runs once daily and fills on weekends: search Aachen day trips on GetYourGuide
- Phantasialand tickets if you extend the Bruhl day for kids, gate price runs well above presale: search Phantasialand tickets on GetYourGuide

Day 1: Land in Cologne and Set Up Your Base
Fly into Cologne Bonn Airport and take the S19 to Koln Hauptbahnhof, 15 minutes and EUR 3.50. Check into a hotel within walking distance of the station, since every day trip this week starts and ends on the same platform. Walk out the north exit and the Dom’s west facade is directly in front of you, free to enter, though the 533-step south tower climb (EUR 8 adult, EUR 4 reduced) is a genuine grind with no elevator.
Spend the afternoon in the Altstadt and the Rhine promenade, then close the day with a proper Kolsch session at Fruh am Dom or Paffgen. The beer comes in tiny 0.2 liter Stange glasses, a Kobes keeps replacing your empty one until you lay a coaster flat on top. A single KVB ticket runs EUR 3.50, a day ticket EUR 8.40 solo or EUR 16.80 for up to five.
Day 2: Bruhl, the Closest UNESCO Palace
Bruhl is 15 to 20 minutes out by S-Bahn or regional train, and it is the easiest genuine UNESCO win near Cologne, one most first-timers skip because Bonn and Aachen get the attention. Augustusburg and Falkenlust palaces form a joint World Heritage site; entry is guided-tour-only with tours running continuously, no reservation needed, but the interiors close on Mondays. If you are traveling with kids, Phantasialand sits next door and is a full day on its own, do not combine the palace and the theme park in one visit. Back in Cologne by early evening, eat in the Sudstadt for something quieter than the Altstadt crowds.
Day 3: Bonn and Beethoven, Home by Dinner
Bonn is the closest and most overrated of the five, a genuine half-day rather than a full one. Beethoven-Haus , the composer’s birthplace, runs EUR 10 adult and EUR 6 reduced, closed Tuesdays, and the regional train takes 20 to 26 minutes. The Museumsmeile and the old federal government quarter sit a bus or tram ride from the Hauptbahnhof, not a walkable extension of a compact old town, so budget transit time. If a delay eats into your week, this is the day trip to cut first.
Day 4: Dusseldorf and the Altbier Rivalry
Dusseldorf runs every 15 to 20 minutes by ICE or RE, fastest at 21 minutes, and it is the better rival-city day trip. Order an Altbier here, never a Kolsch, the decades-old rivalry is only half a joke and locals notice. The Altstadt bills itself as the longest bar in the world, more marketing than fact but not by much, and MedienHafen, the harbor redevelopment with Frank Gehry’s twisted facades, is a 15 to 20 minute walk or tram ride from the Hauptbahnhof. This earns a full day on its own merits.
Day 5: Aachen and Charlemagne’s Throne
Aachen is the marquee day trip of the week. The ICE run takes 33 to 36 minutes; the regional RE1 or RE9 alternative runs 60 to 70 minutes but is covered if you are holding a Deutschland-Ticket. The cathedral , one of the first 12 UNESCO World Heritage sites listed in 1978, is free to enter, but Charlemagne’s marble throne and the imperial chapel are guided-tour-only, EUR 7 adult and EUR 5 reduced, and the English tour runs just once daily at 2pm. Slots fill on weekends. Check bahn.de before you travel this stretch, Deutsche Bahn periodically reroutes the Koln-Aachen line for track work.
Day 6: The Ruhr, Zollverein’s Industrial UNESCO Site
Essen’s Zeche Zollverein , a former coal mine and coking plant turned UNESCO industrial heritage site, sits roughly 55 minutes to an hour out by RE, then a short tram or bus, since the site is not walkable from Essen Hbf. Grounds are free to wander; the Ruhr Museum runs EUR 10 adult and EUR 7 reduced, with a combined ticket covering special exhibitions at EUR 15 adult and EUR 11 reduced. This is a different region entirely, the Ruhr’s industrial heartland rather than the Rhineland. Give it the whole day rather than bolting it onto anything else.
Do You Need 6 Days for Cologne’s Day Trips?
Six days covers five of the six worthwhile day trips, everything except the Romantic Rhine, which genuinely needs its own long day and is better added as a seventh if you have it. Each of the five gets its own day here, with none of them warranting an overnight.
Which Day Trip Should You Cut First?
Cut Bonn first. It is the closest and easiest to reach, which is exactly why it is also the most replaceable: Beethoven-Haus is a half-day museum visit, not a full city, and it does not have Aachen’s UNESCO cathedral or Dusseldorf’s beer rivalry backing it up.
Buy each day’s ticket the night before on the DB Navigator app rather than at the station machine. It flags the cheapest fare tier automatically and saves you from queueing behind a tour group five minutes before your train.
