Cologne

Cologne's KVB network combines underground U-Bahn lines with above-ground tram lines — in the centre they run underground; further out they surface and run as street trams. The system is straightforward and covers all major sights. A 24-hour network ticket for the inner zone costs around €9 and covers unlimited travel — excellent value for a day of sightseeing. The KVB app handles route planning and ticket purchase.

Cologne has an extensive tram network that supplements the underground lines and serves many residential neighbourhoods. Trams run frequently (every 5–10 minutes on main routes) and are easy to use — the same tickets as the U-Bahn apply. For families based in Ehrenfeld or other outer areas, trams are usually the fastest connection to the centre.

The bus network fills in gaps not covered by rail and tram. For most tourist itineraries in Cologne, you will rarely need a bus — the U-Bahn and tram cover the main attractions efficiently. The same KVB ticket covers buses.

Taxis are metered and available at ranks near the Hauptbahnhof and throughout the centre. Uber also operates in Cologne. For families with luggage arriving late at night, taxis from the airport to the city centre cost roughly ~£25–£40. The S-Bahn is almost always faster and cheaper for the airport journey.

The historic core of Cologne is very walkable. The cathedral, the Altstadt, Museum Ludwig, the Roman-Germanic Museum and the Rhine promenade are all within a 10–15 minute walk of each other. I walked everywhere within the Altstadt on both my visits and found the distances comfortable even with teenagers who claim to be tired. The riverfront is flat and smooth — pushchair and wheelchair friendly.

Cologne is reasonably cycle-friendly with dedicated lanes along the Rhine and through many neighbourhoods. Nextbike cycle hire operates across the city with an app-based system. For families comfortable cycling in a city environment, it is a pleasant way to cover the Rhine promenade.

Two to three full days is the right amount for a thorough first visit. Day one: cathedral inside and out, plus the tower climb. Day two: Chocolate Museum, Museum Ludwig and the Rhine promenade. Day three (if you have it): Roman-Germanic Museum, Ehrenfeld exploration and a brewhouse lunch. Cologne is also excellent as a two-night long weekend from the UK.

Absolutely — and I say that as a parent who has had teenagers roll their eyes at many a cathedral. The Cologne Dom earns genuine awe from young people, partly because of its sheer scale and partly because the tower climb is a real physical challenge with a dramatic payoff. The historical facts — 632 years to build, briefly the tallest building in the world — give it context that makes it feel more than just another church. I would rate it among the five most teen-friendly UNESCO sites in Europe.

Kölsch is the pale lager unique to Cologne, served in narrow 200ml glasses. It is an alcoholic beer, and the legal drinking age in Germany is 16 for beer and wine. Children and younger teenagers should ask for alcohol-free alternatives, which all brewhouses carry, or the local apple juice. The brewhouse atmosphere is family-welcoming regardless of what is in the glass.

Cologne is mid-range by German standards — more affordable than Munich, roughly comparable to Hamburg. A family of four eating in a mid-range restaurant should expect to spend around £50–£70 for a meal. Museum entry is generally modest (the cathedral interior is free). I would budget around £100–£140 per day for a family of four covering accommodation, food and entrance fees at a comfortable mid-range level.

The S13 S-Bahn train from Cologne Bonn Airport to Köln Hauptbahnhof runs every 20 minutes and takes around 15–20 minutes. It is cheap (around €3 per person with a standard zone ticket), reliable and drops you right beside the cathedral. I always take the train rather than a taxi — there is no reason to pay for a cab.

Yes, with some planning. The Rhine promenade and the Rheinpark on the east bank are excellent for younger children with space to run. The Chocolate Museum is universally popular. The Cologne Zoo (one of Germany's oldest) is immediately adjacent to the cable car landing on the west bank and is a full day out for younger children. The centre is pushchair-friendly on the flat areas near the river, though the cobblestones in parts of the Altstadt require some care.

Cologne's Weihnachtsmarkt runs from late November through 23 December and is widely considered one of Germany's finest. Several separate markets operate across the city — the one around the cathedral, with the Dom lit up behind the stalls, is particularly atmospheric. Winter temperatures are cold (typically 2–7°C) but manageable with warm layers. A long weekend in early December, combining the market with the cathedral, is a genuinely special family trip.

The main gateway is Cologne Bonn Airport (CGN), around 15 km south-east of the city centre. Several airlines operate direct routes from the UK, including Ryanair and Eurowings from various London airports. Journey times from the UK are typically 1 hour 40 minutes to 2 hours. Fares from London start from around ~£60–£130 return booked in advance, though prices vary significantly by season and booking window. From the airport, the S13 S-Bahn line runs directly to Köln Hauptbahnhof in around 15–20 minutes; a single ticket costs around €3. The airport is compact and manageable for families.

An alternative is flying into Düsseldorf Airport (DUS), which has more frequent London connections. Cologne is 40–50 minutes from Düsseldorf by regional train (RE5 or ICE), making it a very practical alternative when fares are better.

The rail route from London via Eurostar is one I strongly recommend for families who enjoy the journey as part of the trip. Take the Eurostar from London St Pancras to Brussels Midi (~2 hours), then a high-speed Thalys or ICE service from Brussels to Cologne (~1 hour 50 minutes). Total journey time from central London to Köln Hauptbahnhof is around 4.5–5 hours including connection time — competitive with flying once airport time is factored in. Through fares can often be found around ~£90–£180 per person return booked well ahead. The arrival into Köln Hauptbahnhof — right beside the cathedral — is dramatic.

Cologne is approximately 600 km from London via the Channel Tunnel (Le Shuttle) and motorway, around 6–7 hours of driving. Driving makes sense if you are combining Cologne with other Rhine Valley destinations or the Eifel region. Parking in the city centre is expensive; use park-and-ride facilities on the outskirts and take the tram in.
