How to ride public transportation in Helsinki

Helsinki runs on one of Europe’s tidier transit systems: a metro, trams, commuter trains, buses and a harbor ferry, all planned and ticketed by a single authority, HSL, and all covered by the same zone-based fare. Buy a ticket that matches the zones you’re crossing, tap in, and you’re covered across every mode for the length of the ticket.

The basics

The metro is the backbone for getting across the city fast: two lines, M1 and M2, sharing a central trunk and branching out to 30 stations — 19 in Helsinki, 11 in neighboring Espoo. It runs east–west only, so you can’t get lost.

Trams cover the compact downtown core in a dense, frequent network — the classic way to see the city center. Commuter trains, run by VR, fan out from the central railway station on lettered lines (including the airport’s I and P lines) to the wider region. Buses fill in everything else, from trunk routes to suburban feeders. And a small passenger ferry crosses the harbor to the sea fortress island of Suomenlinna, a UNESCO World Heritage Site — it’s run just like any other HSL service and a regular transit ticket covers it.

Fares are zone-based. The region is divided into lettered zones — A (central Helsinki), B and C (Espoo, Vantaa and the inner suburbs, including the airport), and D further out. You buy a ticket covering every zone you’ll pass through: an “AB” ticket for a trip within the city, an “ABC” ticket if you’re headed to or from the airport.

How to pay

You’ve got two main ways to pay, and they’re priced slightly differently:

1. Tap a contactless bank card or your phone (Apple Pay, Google Pay) directly on the reader. It’s the easiest option for visitors — no account or app needed — but it only buys the standard adult fare, at a slightly higher price than buying ahead.
2. Buy ahead in the HSL app, or load a physical HSL card from a service point or ticket machine. This is cheaper than tapping a bank card, and it’s the only way to get a child, student, senior or other discounted fare.

However you pay, show your ticket or card to the reader every time you board — on the bus, tram or train, or at the top of the escalators before the metro platform. On contactless fares, your bank card itself is your ticket; if a ticket inspector asks, you show the same card to their handheld device rather than handing over any paper.

Fares

A single ticket covers unlimited transfers for a set window of time, which gets longer the more zones it covers:

Children (7–17) and other discounted riders pay about half the app/card price. A one-day ticket — unlimited rides, no need to re-tap — costs €10.60 for zones AB, €12.80 for ABC, or €13.80 for ABCD, with cheaper child versions of each. If you’re visiting for a few days and also want museum perks, the Helsinki Card bundles unlimited HSL travel (zones AB or, for the wider-region version, ABC) with free entry to a long list of attractions.

Getting from the airport

Take the I or P train — it doesn’t matter which, since both run in a loop through the same stations. The airport has its own station right beneath the terminal.

• Time: about 30 minutes to the central railway station.
• Cost: an ABC-zone ticket — €4.50 in the HSL app or on an HSL card, €4.80 with a contactless tap.
• Buying a ticket: use the HSL app, or the ticket machine on the platform.
• Alternative: HSL trunk bus line 600 also runs between the airport and downtown, in about 40 minutes, for the same ABC fare.

Apps to download

• HSL app — the official app: buy any ticket, plan a route, see live departures, and get service-disruption alerts, all in one place.
• Google Maps — a solid backup for trip planning, with live HSL timetable data built in.

When it runs

The metro runs roughly from early morning until just after midnight most nights, with later service on Friday and Saturday:

Frequency ranges from every 2 minutes on the shared central section at rush hour to every 10–15 minutes on branches late at night or on Sundays.

There’s no true overnight metro, but night buses — numbered with an “N” suffix (like 21N or 61N) — take over after the regular network winds down, running mainly on Friday and Saturday nights between about 1:00 and 4:00am, when they’re often the only direct ride into the center.

Accessibility

Riders using a manual or electric wheelchair travel free and without a ticket on any HSL service — metro, tram, bus, commuter train or ferry, whether you live there or are just visiting. Mobility scooters used as a mobility aid get the same free, ticket-free ride, but only on the metro, commuter trains and the Suomenlinna ferry — they’re not allowed on buses or trams, which don’t have room for one alongside the wheelchair space. If you have a visual impairment, trams and commuter trains tend to be the easiest way to get around independently, since both have accessible-format timetables and announce stops as you go.

Etiquette & local quirks

• Tap in every time — even if you tapped for an earlier leg of the same journey, trams and buses expect a fresh tap on boarding.
• Day tickets bought at a sales point are now issued as QR codes rather than the old disposable cardboard cards — keep the code handy on your phone or a printout.
• Amex and Diners Club don’t work at HSL’s contactless readers — stick to Visa or Mastercard, or a phone wallet linked to one.
• The Suomenlinna ferry is a genuinely lovely short trip, not just a commute — a regular zone-A ticket covers it, so it’s an easy, cheap half-day detour.

Good to know

• Fare enforcement: inspectors do check tickets on board, and riding without a valid one carries a €100 penalty fare (raised from €80 in January 2024).
