Helsinki public transport: tickets, passes and apps

Decide by how many times you will board, not by how far you go. Helsinki's system is zone and time based: one ticket covers trams, metro, buses, the Suomenlinna ferry and commuter trains inside the zones you paid for, for a set window.

Two rides a day: buy single AB tickets in the HSL app. Three or more rides a day, or any day where you want to hop on and off without counting: a day ticket pays for itself. Stays of two to seven days are cheaper per day on a multi-day ticket than on separate day tickets.

If your trip is mostly walking with one or two rides, singles win. If you plan Suomenlinna, a museum and dinner across town in one day, the day ticket wins.

The HSL app is the default for visitors: buy with a card, keep the ticket on your phone, and show or scan it when you board. Buy before you get on. Trams and the metro have no on-board sales, and inspectors fine passengers without a valid ticket.

Ticket machines at metro and train stations and some tram stops take bank cards. R-kioski shops sell tickets over the counter. A physical travel card is worth it only for longer stays or if you want to top up in cash.

Contactless payment with a bank card or phone is being introduced on HSL services, so check the app or hsl.fi for whether it works on your route before you rely on it. If it is live, tapping in and out is the simplest option for a single ride.

HSL is split into zones A, B, C and D. Central Helsinki is A, Espoo and most inner suburbs are B, and Vantaa with Helsinki-Vantaa airport is C. Buy the zones you actually travel through: AB covers the city, ABC adds the airport, ABCD reaches further out.

A common mistake is buying AB and riding to the airport, which sits in C. Buy ABC for any airport trip. Zone boundaries are not obvious on the map, so check your route in the app before buying.

Tickets are time based, not journey based: inside the validity window you can change between trams, buses, metro, trains and the Suomenlinna ferry as often as you like, as long as you stay inside your zones.

The commuter train is the default: P and I trains run between Helsinki-Vantaa and Helsinki Central in about 30 minutes, roughly every 10–20 minutes through the day. Buy an ABC ticket before boarding; the station is under the terminal.

The Finnair city bus and other airport buses run to the centre and take a similar time, useful if you have heavy bags or arrive when trains are thin. Taxis cost far more and are worth it only late at night or with a group.

If you are staying near the airport, note that the airport is in zone C, so an AB city ticket will not cover the last leg.

Validate or activate your ticket at the start of each journey; a multi-day ticket starts at first use, so do not activate it the night before if you only need it from the morning.

The Suomenlinna ferry is part of HSL, so a valid AB ticket covers it. That alone can justify a day ticket on a sightseeing day.

Peak hours are roughly 07:00–09:00 and 15:00–18:00 on weekdays. Trams and the metro are frequent all day, and the network is small enough to walk between many stops.

For a short visit, pair a day ticket with walking: central Helsinki is compact, and the tram is often faster than waiting for a specific bus.
