The Stockholm–Helsinki ferry

The overnight boat between Helsinki and Stockholm is the best way to travel between the two cities, and one of the few journeys left where the transport is the trip. You leave one capital at five in the afternoon, sail out through the Helsinki archipelago in the evening light, eat, sleep, wake up to the Stockholm archipelago, and walk off in the other capital at ten the next morning. A flight takes an hour and saves you nothing once you count the airports and a hotel night.

Two companies run it, one ship per company each night in each direction.

Silja or Viking

All times are local, and Stockholm is one hour behind Helsinki, which is why the westbound trip looks shorter on paper than it is. Tallink puts the crossing at about 17 hours. The Silja times are from Tallink's October 2026 sailings; Viking's are from its timetable valid from 1 October 2026 (until 30 September, Viking leaves Stockholm at 16:30).

The honest difference between them is smaller than the loyalty suggests. The Silja ships have the famous indoor promenade — a street of shops and restaurants running down the middle of the ship, with cabins whose windows look onto it. The Viking ships are more conventional inside, and the timetables are within half an hour of each other. The practical difference is where each one lands you in Stockholm, which is below. If the ship itself is the point, Silja.

Getting to the Helsinki terminals

• Olympia terminal (Silja). In the South Harbour, a short walk south of the Market Square. Trams 2 and 3 stop at the terminal. Check-in is open 14:45–16:15 every day and is cashless.
• Katajanokka terminal (Viking). On the Katajanokka peninsula east of the Market Square. Tram 5 goes to the terminal from the railway station; tram 4 stops at Vyökatu, 400 m away.

Both are within walking distance of the centre. Neither is the West Harbour, which is where the Tallinn boats go from — see the Helsinki–Tallinn ferry if you are doing both.

Arriving in Stockholm

The two terminals put you in quite different places. Stadsgården (Viking) is on the Södermalm quayside; you walk off the ship and along the water to Slussen and the old town, Gamla stan, in well under half an hour, and the view of the city from that walk is the best introduction to it. Värtahamnen (Silja) is in the north-east of the city among the port buildings; the nearest metro station is Gärdet, on the red line, a walk away, and from there it is a few stops into the centre. Neither is difficult, but with heavy bags and a hotel in Södermalm or Gamla stan, Viking saves you a journey.

Four in the morning in Åland

Both ships stop in Mariehamn, in the Åland Islands, in the middle of the night. Westbound, Viking arrives at 04:25 and leaves at 04:30; eastbound it calls at 22:55. Tallink's stop is at the same kind of hour. You will not see anything, but you may feel the engines change and hear the announcement. People do get off here: Åland is an autonomous Finnish region with its own flag and stamps, and if you want to break the journey it is the one stop on the way.

Which cabin

Book one. The boat is not built for sitting up all night, and the point of the trip is waking up rested in another capital.

Both companies sell cabins in a long ladder of classes. On Silja they run from C-Economy Inside and B-Standard Inside through A-Standard Sea view, Promenade cabins, Deluxe and Commodore to suites. On Viking's Gabriella, from Economy and Inside Standard through Seaside Standard and Seaside Premium to a suite in the bow. What actually matters:

• Inside or outside. An inside cabin has no window and is completely dark, which some people sleep better in and others find oppressive. It is the cheap way to do the trip and perfectly comfortable for one night.
• A window over the sea is worth paying for once, for the archipelago at 8 in the morning when you come into Stockholm or Helsinki. The last two hours of the crossing thread between thousands of islands and are the best part of the voyage.
• Silja's promenade cabins look inward onto the shopping street, not out to sea. Charming or strange depending on the person; not a sea view.
• Breakfast is included with Viking's Suite and Seaside Premium cabins on night sailings. Otherwise, the buffet breakfast is a separate purchase, and it is the one meal we would buy on board.

One Viking rule people trip over: you may not drink your own alcohol, or alcohol from the ship's shop, in the cabin. Viking's fine is €120.

A day in Stockholm without a hotel

Tallink sells a two-night round trip: out from Helsinki at 16:45, a day in Stockholm, and back the same evening, keeping the same cabin both nights. Tallink gives the time ashore as 6 hours 30 minutes. It is a real option for seeing Stockholm's old town and a museum, and a classic Finnish long weekend. It is not enough time to do more than the centre.

The Turku alternative

The shorter crossing to Stockholm leaves from Turku, on the south-west coast, with three departures a day between the two companies. Viking runs two of them, on Viking Glory and Viking Grace:

Tallink's Baltic Princess also sails from Turku at 19:30, stopping at Långnäs at 00:40, and leaves Stockholm at 07:00 for Turku at 18:30. The morning sailing is the one to take if you want the archipelago in daylight — the whole Turku archipelago, Åland and the Stockholm skerries in one day, at sea level.

If you are driving, the road to Turku is the E18: the Helsinki to Turku road page has the conditions and cameras along it today, and the Turku harbour camera is on our cameras page.

A few practical notes

• ID. Sweden and Finland are both in Schengen, but carry a passport or national ID card; the ferry companies check.
• January. Both Viking ships take turns out of service for maintenance in January 2027, and Gabriella moves to the Turku route for some weeks after that. Check the date before booking a winter trip.
• Christmas. The Christmas Eve sailings leave earlier, at 14:00 on Viking.
• Time. Put your watch back an hour going west and forward going east.
• Light. The sail-out through the Helsinki archipelago is the best hour of the trip, and whether you see it depends on the month. In mid-October the sun still sets in Helsinki after six in the evening; from November, when the clocks have gone back, it sets before the ships leave, and you sail out in the dark. The Helsinki daylight page has today's sunset.
