Helsinki West Terminal: Löyly and Jätkäsaari
Part of the full Helsinki Layover: Suomenlinna Fortress, HEL

Löyly’s timber sauna mound sits on the open shore about two kilometres south of Helsinki’s West Terminal, with Hyväntoivonpuisto’s mile of park path running the other way through Jätkäsaari, which makes this a waterfront afternoon rather than a run at the old town.
Löyly’s timber sauna mound on the Hernesaari shore
Avanto Architects finished it in 2016 on the rocky edge at Hernesaarenranta, and from outside it reads as a low hill of angled timber rather than a building: glulam slats laid at a triangular profile so the wall catches light differently through the day and screens the windows without blocking the sea. A public staircase climbs the side of it to a roof terrace, and that part costs nothing whether or not you go in.

Inside are three saunas, a genuine smoke sauna and two wood-heated ones, with a terrace and a ladder straight down into the Gulf of Finland that people use through the winter as well as the summer. A session is roughly 19 to 24 euros, and the smoke sauna wants a booking because it heats on a fixed schedule rather than on demand. If the timings do not work, a floating sauna on the harbour books in shorter slots and sits closer to the centre.
It is a walk of about two kilometres south along the water from the terminal, or a short bus ride, and the last stretch is open shoreline with nothing to shelter under.
Hyväntoivonpuisto, the park down the spine of Jätkäsaari
The park is the one continuous green line through a district otherwise made entirely of new apartment blocks, and it will be 88 metres wide and a little over a kilometre long when the last section is planted. It is also the main pedestrian and cycling route from Ruoholahti out to the sea, which means a red-surfaced path with no traffic lights on it.

The trees are young because all of this is recent: the city has said the park will read as a forest in about twenty years, which is an unusually honest thing for a parks department to publish. The other survivors of what was here before are the gantry cranes, left standing between the blocks after the container traffic moved out to Vuosaari in 2008 and the cargo quays were handed over to housing.
The Tallinn boats load from two separate halls
Tallink Silja and Eckerö Line both sail to Tallinn from this site, but not from the same building: West Terminal 1 and West Terminal 2, the latter opened in 2017, stand several hundred metres apart with separate check-in halls, and the name on the ticket is the one that matters. Viking Line’s Tallinn boats do not come here at all; they load at Katajanokka on the far side of the city centre.
The tram loop runs to the terminal door and reaches the middle of Helsinki in about ten minutes, which is the fastest link out of any of the city’s ferry berths. What the harbour has none of is a railway, so everything from here starts with that tram, and the quay between the two halls is open ground with the wind off the water and no left-luggage desk on the landside of either building.
Anyone hoping to swim indoors instead should know the plan is still a building site: the Bunkkeri warehouse that stood in the middle of Jätkäsaari has been demolished, and the swimming and sports centre replacing it, with a 50-metre pool and a water slide, is not expected to open until around the turn of 2029 and 2030.
No railway in the harbour, so it is a tram then a train
Getting to Helsinki Airport from the quay takes two legs and about an hour. The tram covers the three kilometres to Helsinki Central Railway Station in roughly ten minutes; from there the I train runs out through Tikkurila on the eastern side of the loop in about 27 minutes, and the P train takes the western side through Myyrmäki in about 32, with a departure roughly every ten minutes through the day.
One ABC-zone ticket, the fare band that reaches the airport, costs 4.80 euros in 2026 on a contactless card and covers the tram and the train together inside its 90-minute window, so buy it once at the terminal rather than twice. The airport platform is deep and the escalator climb long, so treat the honest figure as an hour from the quay to the departures hall.
This is the version of a Helsinki stop that suits arriving by sea and leaving by air, all of it on the western waterfront. With four hours or more, and especially if you came in the other direction, the main Helsinki guide crosses the harbour to the sea fortress instead, and that is a trip worth doing with the bag already left behind.
Frequently asked questions
What should I do during a layover near the West Terminal (Länsiterminaali) in Helsinki?
Löyly, a public sauna built as a timber mound on the Hernesaari shore, is the one thing out here worth planning around: three wood-heated saunas, a ladder into the open sea and a roof you can climb for nothing. Hyväntoivonpuisto, the park laid down the spine of Jätkäsaari, runs from the terminal back towards Ruoholahti on a red-surfaced path with no road crossings. The terminal building itself is where the Tallinn boats load, and the tram stop is at its door. Three hours covers the sauna and the walk; the smoke sauna needs booking ahead, the park does not.
Which Helsinki terminal do the Tallinn ferries leave from?
Two of the three operators use the West Terminal in Jätkäsaari and one does not, which is the mistake worth avoiding. Tallink Silja and Eckerö Line both sail to Tallinn from here, and there are two buildings on the site, West Terminal 1 and the newer West Terminal 2 of 2017, several hundred metres apart with different check-in halls. Viking Line's Tallinn service loads at Katajanokka on the other side of the city centre instead, about half an hour away by tram. Check the terminal name on the ticket rather than the port.
Can you actually use Löyly on a tight schedule?
Yes, but budget more than the session itself. The smoke sauna and the wood-burning sauna open at 4pm on Monday to Wednesday and at 1pm from Thursday onward, closing at 10pm most nights and 11pm on Friday and Saturday. A session runs around 19 to 24 euros, towels and seat covers are hired at the desk, and the smoke sauna has to be booked in advance because it is heated on a fixed schedule. Allow forty minutes on top of your time in the heat for cooling down, showering and drying, which is what catches people with a boat or a flight to make.
How do you get from the West Terminal to Helsinki Airport?
In two legs, because there is no rail line into the harbour. A tram from the terminal door reaches Helsinki Central Railway Station in about ten minutes over three kilometres, and from there the I train runs out to Helsinki Airport through Tikkurila in around 27 minutes and the P train the western way through Myyrmäki in about 32, roughly every ten minutes. One ABC-zone ticket at 4.80 euros in 2026 covers both legs inside its 90-minute validity. Counting the escalators up from the deep airport platform, allow an hour from the quay and leave about two and a half hours before departure.
