Navigating Helsinki is remarkably easy and efficient, thanks to a world-class public transport system managed by HSL (Helsingin seudun liikenne). The network is fully integrated, meaning a single ticket allows you to switch seamlessly between trams, buses, the metro, commuter trains, and even the municipal ferry. For most tourists, this system is the most convenient and affordable way to explore the city and its surrounding regions.
The most iconic mode of transport in the city center is the tram. Easily customizable with their green and yellow livery, the trams weave through the main streets and pass many major attractions, making them perfect for sightseeing. Routes 2 and 3 are particularly popular among visitors for a self-guided tour of the downtown area. For longer distances, the Helsinki Metro—the northernmost metro system in the world—offers a fast connection between the city center, the eastern suburbs, and the neighboring city of Espoo. The metro trains are distinctive for their bright orange color, and the network is simple to navigate as it consists of a single line that branches into two at the eastern end.
Buses complement the rail network, covering areas that trams and the metro do not reach. They are clean, punctual, and run frequently. Additionally, the commuter train network is vital for reaching destinations further afield, including the direct connection to the airport via the Ring Rail Line. A unique feature of the local transport system is the municipal ferry to the Suomenlinna sea fortress. Departing from the Market Square, this ferry accepts standard public transport tickets, offering a scenic mini-cruise at no extra cost.
The payment system is based on geographical zones (A, B, C, and D). Most tourist attractions and hotels are located within zones A and B, so an AB ticket is usually sufficient for daily exploration. However, if you are traveling to or from the airport, you will need an ABC ticket. Fares are reasonable, with a single ticket costing a few euros and remaining valid for 80 to 110 minutes depending on the zones purchased. Unlimited transfers are allowed within this time window.
For the best experience, tourists are highly advised to download the HSL app. It is the easiest way to purchase single tickets or day passes directly on your phone. Alternatively, you can buy physical tickets from blue ticket machines at stations, or from R-kioski convenience stores found throughout the city. Please note that you cannot buy tickets from drivers on trams, trains, or the metro, and cash is generally not accepted on board buses. If you use a physical travel card or a single paper ticket, you must validate it by tapping it against the card reader upon boarding or entering the platform area.
The transport system operates on an "open" basis, meaning there are no turnstiles at most metro or train stations. However, ticket inspectors patrol frequently, and traveling without a valid ticket results in a hefty penalty fare. In terms of operating hours, the metro and trams typically run from early morning until around midnight or 1:00 AM. On weekends, night buses extend the service, ensuring you can return to your accommodation safely after a night out.
If you prefer active mobility, Helsinki offers an excellent alternative in the form of city bikes. During the warmer months (typically April to October), bright yellow bikes are available at stations across the city for a very low fee. They are extremely popular with locals and visitors alike for short trips. Electric scooters are also widely available for rent via various apps. While taxis are reliable and safe, they can be quite expensive compared to public transport; it is recommended to use ride-hailing apps or official taxi stands rather than hailing them from the street.
