In this guide
💡 The Short Version: Our judgement, not a ranking: pick Tallinn for one or two days on foot in a walled medieval Old Town, on a €2 one-hour ticket, with no tourist tax. Pick Helsinki for the sea, public saunas and art museums, and for a day on the island fortress of Suomenlinna, which costs an €3.50 ferry ticket. Both use the euro. You can do both: the ferry is two hours on Tallink’s MyStar or Megastar, with up to six departures a day, and the Helsinki Christmas market and Tallinn’s overlap from 27 November to 22 December 2026. Or book a tour: a guided Tallinn day tour with the ferryad or a Helsinki day trip with the ferry and a guided tourad puts the crossing and the guide in one booking (GetYourGuide).
⚠️ Take a passport or an EU identity card for the ferry. Eckerö Line says a driving licence is not accepted for the crossing, and children need their own document. Tallink’s gate closes 20 minutes before departure. In winter, check the Monday: Helsinki’s Ateneum and Uspenski Cathedral are shut, and so are Tallinn’s Kumu and, from October to April, Seaplane Harbour, the Kadriorg Art Museum and Kiek in de Kök.

On the prices in the table, Tallinn’s transport and big museums cost less. The Tallinn Card at €45 a day is cheaper than the Helsinki CITY card at €62, but both are built for days of paid museums, and neither pays on a day of walking.
Which city for whom
Each pick below is our judgement, built on the figures in the table.
First-timers: Tallinn for a day or two, Helsinki for three
Tallinn fits a short first visit. The Old Town on the UNESCO World Heritage List is a walk, the Town Hall and square, Toompea and the town wall sit within it, and Tallinn in 1 or 2 days fits a weekend. Helsinki spreads along a harbour: Senate Square and the cathedral, the Old Market Hall, Oodi and Suomenlinna are a tram or a ferry apart, and Helsinki in 1 or 2 days is a plan for the layover or the weekend.

Saunas and the sea: Helsinki
Helsinki has the public saunas at a range of prices: Löyly on the sea front at €29 for two hours, Allas Sea Pool beside Market Square from €19, Kotiharju in Kallio at €16, which Helsinki’s page calls the city’s last public wood-burning sauna, and the volunteer-run Sompasauna, free and open 24 hours. Tallinn’s sauna is more of a private booking: Põhjala’s taproom rents one for up to eight people at €80 for the first hour, and Iglupark in Noblessner has private saunas from 11:00 to 23:00 for at least two hours.
Art and museums: Helsinki for the collections, Tallinn for the price
Helsinki’s art museums are the heavier set: the Ateneum at €23 and Kiasma at €23, with Amos Rex, the Sinebrychoff Art Museum and others on the Helsinki Card. The National Museum is closed from 2024 to 2027. Tallinn has Kumu at €16, open to 20:00 on Thursdays, and the Kadriorg Art Museum at €15, open to 20:00 on Wednesdays. Both cities are shut on a Monday for the main art museum, so put a Monday on the free sights: Oodi, the City Museum and the Sibelius Monument in Helsinki, and the Toompea viewpoints, Alexander Nevsky Cathedral and Kadriorg Park in Tallinn.
A tight budget: Tallinn, on the prices here
A day of Tallinn transport is €5.50 against €10.60 in Helsinki, and the airport tram is €2 against €4.80 for the Helsinki train. Tallinn charges no tourist tax. The costs that stay are the museums: Seaplane Harbour is €22 and the TV Tower €18 online, so the Tallinn Card pays only if you spend the days in them. Helsinki’s free things are real, but Uspenski Cathedral charges €5 and the Rock Church €8.
Both cities: a night each, or a day across
The crossing is two hours on Tallink’s MyStar or Megastar, with up to six departures a day, from West Terminal 2 in Helsinki (trams 7 and 9) to Terminal D in Tallinn. Viking Line’s Viking XPRS takes about 2.5 hours from Katajanokka to Terminal A, and Eckerö Line’s MS Finlandia runs three departures a day from West Terminal 2. Finland and Estonia share a time zone, and both use the euro. Either terminal in Tallinn is about 15 minutes’ walk from the Old Town. For a day trip, Tallinn from Helsinki and Helsinki from Tallinn compare the operators and give a route for the day.

Helsinki or Tallinn for Christmas
Tallinn’s market on Town Hall Square opens on 20 November 2026 at 18:00 and runs to 6 January 2027, daily 10:00 to 20:00, with hot drinks until 22:00 and until 23:00 on Fridays and Saturdays. It is free to enter, the reusable cups and plates carry a €2 deposit, and it is open on 31 December. Helsinki’s market on Senate Square runs from 27 November to 22 December 2026, 11:00 to 19:00 on Monday to Thursday and Sunday and 11:00 to 20:00 on Friday and Saturday. Our judgement: Tallinn for a trip that runs past Christmas or into the new year, Helsinki for a date in the first three weeks of December, with Lux Helsinki following from 30 December to 6 January 2027. Both cities have short days: 5 h 53 min of daylight in Helsinki on 15 December and 6 h 03 min in Tallinn on 21 December 2026. On 24 December Helsinki runs a Sunday transport timetable, and Kumu and Kiek in de Kök in Tallinn are shut. The Christmas market cities compared sets both against the other markets.
Day trips and where to stay
The day trips differ. From Helsinki, Porvoo is about 50 minutes by bus, and Nuuksio National Park is an HSL train and a connecting bus. From Tallinn, Haapsalu is a direct coach of 1 hour 35 minutes to 1 hour 50 minutes, and the Viru Bog in Lahemaa is under 70 minutes by direct bus. The full lists are day trips from Helsinki and day trips from Tallinn.
For a first visit, stay in Helsinki around the Central Station or the Esplanade, or in Jätkäsaari or Katajanokka, beside the ferry terminals (where to stay in Helsinki), and in Tallinn in the Old Town, the city centre or Kalamaja (where to stay in Tallinn). For what to book in each, see Helsinki and Tallinn; for the museum cities side by side, see museum city breaks; for the weather month by month, see where to go each month. For Tallinn against Riga, see Tallinn vs Riga.
