Bus Tours in Helsinki: What to Know
Helsinki’s compact center means a bus tour here is really two separate things: one loop around the city sights, and a set of coaches heading out to nearby towns for the day.
The hop-on-hop-off loop
Stromma runs Helsinki’s sightseeing bus, a hop-on-hop-off route departing from Senate Square that operates May through September. A day ticket costs EUR 36 and lets you get on and off as many times as you like along the route, which is the standard way to cover the city’s spread-out landmarks without walking between all of them in one sitting. Search current Stromma hop-on-hop-off availability on GetYourGuide or check myhelsinki.fi for the season’s operating dates before you plan a day around it, since the route only runs in summer.
Coach to Porvoo instead of a city loop
If a “bus tour” for you means a day trip rather than a city loop, OnniBus runs frequent express coaches from the Kamppi bus terminal to Porvoo, Finland’s second-oldest town, in about 50 minutes each way for roughly EUR 5 to EUR 10 one way. Porvoo’s red-ochre riverside storehouses and cobblestone lanes make for an easy half-day out and back. Book Porvoo day-trip tickets and check schedules at onnibus.com . One thing a coach will not do is get you to Tallinn: that crossing is a ferry over the Gulf of Finland, not a bus route, so do not book a coach ticket expecting it to reach Estonia.
Local buses fill in where trams don’t go
For getting around the city day to day, trams 2, 3, and 4 cover most of the central sights, but buses handle a couple of routes trams don’t reach. Bus 24 is how you get to Seurasaari Open-Air Museum, since the island connects to the mainland by a pedestrian footbridge rather than a ferry. Bus 245A, picked up after the commuter train to Espoo, is the connection to Nuuksio National Park’s trailheads. Both run on a standard HSL zone ticket (AB for the city, ABC if your trip crosses into Espoo), bought through the HSL app before boarding. hsl.fi has the current route maps and zone boundaries.
A winter note for anyone waiting at a stop
Between late autumn and early spring, granite curbs and bus-stop platforms glaze over with black ice (pääkallokeli) that is nearly invisible until you’re standing on it. Wear boots with deep tread, or pick up a pair of slip-on studded grips (liukuesteet) from any pharmacy, when you’re waiting for a coach or stepping down from one onto an icy curb.
