There are many ways to understand the Nordic countries.

You can study happiness rankings, tax levels, coffee consumption, minimalist furniture or the slightly suspicious enthusiasm for salty liquorice.

Or you can go underground.

Because Nordic metro systems do more than move people from A to B. Look closely and they tell you quite a lot about the cities above them.

Copenhagen is sleek, automated and quietly pleased with itself. Stockholm is dramatic and artistic. Oslo is practical but keeps trying to take you hiking. Helsinki is calm, efficient and wondering why everyone else is making such a fuss.

And Reykjavík?

Reykjavík has buses, volcanoes and weather. Apparently that is enough.

Which Nordic capitals actually have a metro?

The Nordic metro club is surprisingly exclusive.

Copenhagen has the Metro. Stockholm has the Tunnelbana. Oslo has the T-bane. Helsinki has the Metro.

Reykjavík has no metro, and neither do the Faroe Islands or Greenland. Given the population and geography in some of those places, building one would probably result in a very expensive tunnel used by twelve people and a sheep.

For visitors, though, the four Nordic metro systems that do exist are remarkably useful — and remarkably different.

Copenhagen Metro: the driverless Danish show-off

The Copenhagen Metro is exactly the sort of public transport system Copenhagen would design.

Clean. Automatic. Open 24 hours a day. Very little unnecessary drama.

It connects Copenhagen Airport with the city center and links hotels, neighbourhoods, conference areas and major attractions across the capital. If you are planning a trip through Denmark, it is one of the reasons Copenhagen is such an easy city to navigate without a car.

And people are using it. In 2025, the Copenhagen Metro carried 135 million passengers, while more than 99% of departures ran on time.

There is also the great democratic pleasure of standing at the front window of a driverless train and pretending to drive it.

Childish?

Absolutely.

Will we continue doing it?

Absolutely.

Stockholm Metro: public transport with a drama degree

Stockholm looked at the basic concept of a metro station and apparently thought:

“Useful. But does it have enough art?”

The answer was no.

Today, 94 of Stockholm Metro’s 100 stations contain some form of artistic design, and the network is often described as the world’s longest art exhibition. At some stations, the exposed rock walls turn platforms into giant painted caves. Others feel like archaeological sites, futuristic film sets or the result of giving an artist several thousand square meters and telling them to have fun.

That makes the Stockholm Tunnelbana unusual for visitors: taking the metro can genuinely become part of the sightseeing.

So while exploring Sweden, you may find yourself deliberately getting off at stations you do not need.

Not because you are lost.

Because this time, oddly enough, the metro station is the attraction.

Oslo T-bane: the metro that wants to go hiking

Oslo’s T-bane operates five lines across the Norwegian capital.

But Oslo has a problem.

It is Norwegian.

So even its metro struggles to remain entirely urban.

The network connects central Oslo with residential areas, business districts and neighbourhoods across the city, but it also stretches towards forests, hills and outdoor recreation. This is public transport that sometimes seems only one stop away from asking whether you remembered your hiking boots.

That relationship between city and nature is one of the reasons Oslo works so well as a gateway to Norway. You can be surrounded by offices, restaurants and contemporary architecture, then suddenly find yourself looking at trees and wondering whether everyone else on the train owns substantially better outdoor clothing than you do.

They probably do.

Helsinki Metro: no fuss, no chaos, just Finland

Helsinki Metro is the quiet one.

Of course it is.

It does not need to become an underground art museum. It does not need to show off about being driverless. It does not appear particularly interested in impressing you.

It simply works.

According to HSL’s latest annual figures, the Helsinki Metro carried around 238,000 passengers on an average weekday in October 2025, operating across two metro lines.

That feels extremely Finnish.

Efficient. Useful. No speech required.

And that understated approach fits Finland rather well. Helsinki’s public transport makes it relatively painless to combine neighbourhoods, restaurants, waterfront areas, meeting venues and the wider capital region.

It has solved the transport problem and would now quite like us to stop talking about it.

Reykjavík: “Metro? We have buses.”

And then there is Reykjavík.

No metro. No underground art gallery. No driverless trains.

Instead, the greater Reykjavík area uses the Strætó bus network, with many routes operating every 15 minutes during peak periods.

Which makes sense.

A metropolitan railway system becomes slightly harder to justify when your entire country has fewer people than many European cities.

Besides, when travelling around Iceland, the more pressing infrastructure questions usually involve mountains, lava fields, snow, fjords or whether the road ahead still technically exists.

Reykjavík seems perfectly comfortable with its decision.

But the real story? The Nordics are still digging

What makes Nordic metro systems especially interesting is that three of these capitals are not remotely finished.

Copenhagen’s future M5 is planned as a new nine-station metro line. The first six stations are scheduled to open in 2036, connecting Copenhagen Central Station with parts of Amager and Prags Boulevard. A second phase towards Refshaleøen and Lynetteholm is planned for later. As of September 2026, Metroselskabet is already tendering the construction contract for the first phase.

There is even the much bigger idea of an Øresund Metro between Copenhagen and Malmö. The proposal would cut the city-center journey to around 20 minutes and could bring around one million additional people within commuting distance across the Øresund region.

A metro between Denmark and Sweden?

That is either wildly ambitious or completely logical.

In the Nordics, it can easily be both.

Stockholm, meanwhile, is undertaking its largest metro expansion in 50 years: 18 new stations and 30 kilometers of new track, extending the network towards Barkarby, Arenastaden and Nacka, with a new underground line between Fridhemsplan and Älvsjö.

Oslo is building too. The Fornebu Line will add around 7.7 kilometers of tunnel and six new underground stations between Majorstuen and Fornebu. It is currently planned to open in 2029.

Helsinki, predictably, is taking the less theatrical route. HSL’s 2026–2027 plan has no changes planned to regular Metro service, although major infrastructure works will affect parts of the network during 2027.

Copenhagen builds a new line.

Stockholm builds 18 stations.

Oslo digs towards a new business district.

Helsinki checks that the bridge works properly.

Everyone stays in character.

So which Nordic metro is the best?

That depends entirely on what you want.

Copenhagen is the sleek one.

Stockholm is the spectacular one.

Oslo is the scenic one.

Helsinki is the sensible one.

Trying to pick a winner almost misses the point, because each system fits its city unusually well.

Copenhagen says: Relax. We automated it.

Stockholm says: Your commute needs more art.

Oslo says: This train may eventually lead to a forest.

Helsinki says: It works. Why are you making this emotional?

And Reykjavík says: We are standing on a volcanic island in the North Atlantic. Please be serious.

Why Nordic public transport matters for visitors

For travellers, good public transport is not simply convenient. It changes what is possible.

It allows you to stay in more interesting neighbourhoods, reach restaurants and attractions easily and spend less time sitting in traffic.

For meetings, incentives and corporate groups, it matters even more. Hotels, venues, airports and experiences become easier to combine, and not every movement requires another private coach waiting outside.

That is why transport is part of the planning when Best of Nordic creates corporate travel, incentives and tailor-made Nordic programs. The best itinerary is not simply a list of great places. It also needs to work.

Sometimes that means a private transfer.

Sometimes a boat.

Sometimes a scenic train.

And sometimes the smartest Nordic experience begins by walking downstairs and getting on the metro.

Preferably in the right direction.
