Helsinki

Jump to what you need
📍Region
Helsinki is the capital of Finland and its largest city, in the Uusimaa region, on the country's south coast, looking out over the Gulf of Finland (the Baltic Sea). It is built on a peninsula and a string of islands, and its metropolitan area — which includes Espoo and Vantaa — is home to around 1.5 million people. It is the country's political, economic, university and cultural centre, famous for its design, its saunas, its neoclassical and modernist architecture, and its close relationship with the sea.
📌Getting there
Helsinki-Vantaa airport (HEL) is about 18 km north of the centre and is the great air hub of northern Europe, with Finnair as flag carrier. It connects to the centre in 30 minutes on the commuter train (rail lines I and P, HSL network) that reaches the central station. From Buenos Aires you fly with one or two European stopovers. Helsinki is also a huge Baltic ferry port: ships from Tallink Silja, Viking Line and Eckerö Line arrive from Tallinn (2 h), Stockholm (overnight) and the Åland Islands.
📌Getting around
Public transport is run by HSL (Helsingin seudun liikenne): metro, trams, buses, commuter trains and the ferry to Suomenlinna, all on the same zone-based ticket. You pay with a contactless bank card, with the HSL app or at machines. The centre is compact and very walkable, and the trams (such as the 2 and the 4) are a cheap and lovely way to get around it. The city is flat and very bike friendly (public scheme in summer).
📌Best time to go
Summer (June to August) is the best season: very long days — around the solstice it hardly gets dark —, terraces, markets, islands, ferries and swimming in the sea. June and July are the star months. May and early September are good and less crowded. Winter is cold, dark and short on daylight, but it has its magic: snow, Christmas markets, steaming saunas and, in some years, skating on the frozen sea. December draws people for Christmas.
📌Suggested days
With 2 or 3 days you get to know the city well: Senate Square and the cathedral, the market and the harbour, the island fortress of Suomenlinna, the church carved into the rock (Temppeliaukio), the design district and a museum or two. With 4 or 5 days you can add a trip to Porvoo, a day of saunas and beach, or a ferry getaway to Tallinn (Estonia), only 2 hours away.
📌Language and currency
The official languages are Finnish and Swedish (Helsinki is bilingual: Helsinki/Helsingfors), and English is spoken with great ease. The currency is the euro (€): Finland is the only Nordic country that uses it. It is a virtually cashless city: almost everything is paid by card or phone, even small amounts. Tap water is drinkable and of excellent quality.

🌤️ Weather in Helsinki
Loading weather…

Helsinki is a young, bright and surprisingly relaxed Nordic capital, wedged between the Baltic Sea and the forests of southern Finland. It does not have the monumental scale of other European capitals: its charm lies in the mix of Russian neoclassical architecture around Senate Square, Art Nouveau modernist buildings, Scandinavian design everywhere and an everyday relationship with water, islands and the sauna that defines the Finnish way of life.

It is the design city par excellence — it was World Design Capital in 2012 — with its Design District of shops, studios and museums, brands such as Marimekko and Iittala, and a food scene that champions the flavours of the northern forest and sea. But it is also a city of steaming public saunas by the water, of covered markets where you can try salmon and cinnamon buns, and of ferries that take you in fifteen minutes to an 18th-century fortress listed as a World Heritage Site.

Gateway to Finland and a bridge between Scandinavia, the Baltic and Russia, Helsinki combines Nordic efficiency with a quiet warmth. This guide covers the essentials of the Finnish capital with a practical, friendly eye: what to see, how to get around with the HSL card, what it costs, where to eat and how to enjoy it both under the midnight sun and in the depths of winter.

📖 History of Helsinki

Helsinki was founded in 1550 by king Gustav Vasa of Sweden, as a trading port meant to compete with Tallinn (Reval), on the other side of the gulf. For centuries it was a small and rather insignificant town in the shadow of Turku, the old capital. Everything changed when, after the Finnish War (1808-1809), the country passed from Swedish to Russian hands and became the Grand Duchy of Finland under the tsar. In 1812, Alexander I moved the capital from Turku to Helsinki, closer to Saint Petersburg, and ordered its centre rebuilt in an imposing neoclassical style — Senate Square — the work of the architect Carl Ludvig Engel. Since independence in 1917, Helsinki has been the capital of the Republic of Finland and the heart of a country that made design, education and technology its trademark. The full history is on our history page.

🗺️ What to see

1
Suomenlinna (the fortress on the sea, a Unesco World Heritage Site)
An 18th-century sea fortress spread over several islands, 15 minutes by ferry from the centre.
Suomenlinna ('the castle of Finland') is, for many people, the essential visit in Helsinki. It is an enormous 18th-century sea fortress built by the Swedes on a group of islands at the entrance to the harbour, listed as a Unesco World Heritage Site. Construction began in 1748 under the name Sveaborg to defend the region against Russia; in time it fell into Russian hands and then passed to independent Finland, which renamed it Suomenlinna in 1918. Today it is both an open-air museum and a living neighbourhood where some 800 people live. You walk among walls, tunnels, gun batteries, courtyards and dockyards, which include the Second World War submarine Vesikko, the church-lighthouse, the King's Gate (the monumental gate facing the sea) and several small museums. It is an ideal half-day plan: walking, having a picnic on the rocks facing the Baltic and feeling centuries of northern military history. Getting there: on the public HSL ferry from the Market Square (Kauppatori), a crossing of about 15 minutes included in the normal transport ticket. Best time: summer, with everything open and long days, though the ferry runs all year. Tips: wear comfortable shoes and bring a layer (it gets windy); download the map, because the islands are large. Entry to the fortress is free; you only pay for some museums.
ℹ️ Distance: Islands facing the centre; HSL ferry from the Market Square (Kauppatori), 15 min · Best time: Summer (everything open); the ferry runs all year · Entry: Walking the fortress is free; the ferry is included in the HSL AB ticket (3.30 € one way). Museums inside charge separately (source: suomenlinna.fi / hsl.fi, verified July 2026) · Duration: Half a day (3 to 5 hours)

Senate Square and Helsinki Cathedral
The white neoclassical ensemble that is the city's postcard, the work of Carl Ludvig Engel.
Senate Square (Senaatintori) is the monumental heart of Helsinki and its most recognisable image. It is a neoclassical ensemble raised in the first half of the 19th century, when Helsinki became capital of the Grand Duchy and the tsar ordered it given a centre worthy of a capital. The German architect Carl Ludvig Engel designed the ensemble taking inspiration from Saint Petersburg, with pastel-coloured buildings around the statue of tsar Alexander II. It is dominated by the Lutheran Helsinki Cathedral (Tuomiokirkko), dazzling white, with its great green dome and its flight of steps, completed in 1852. It is the symbol of the city and a symbolic lookout over the harbour. Around the square stand the Government Palace (the Senate), the main building of the University of Helsinki and Sederholm House, the oldest in the centre (1757). This is the place to start the visit, take the classic photo from the top of the steps and grasp at a glance the city's Russian, imperial past. In summer the square hosts events; in December, one of Helsinki's best loved Christmas markets. Getting there: right in the centre, a few minutes' walk from the Market Square and the station; trams 2 and 4. Best time: any day; especially lovely in good light. Tips: entry to the cathedral is free; climb the steps for the panorama. Combine it with the Market Square, the harbour and the Uspenski Orthodox cathedral, very close by.
ℹ️ Distance: Centre; trams 2 and 4, on foot from the station · Best time: Any day; Christmas market in December · Entry: Square and Lutheran cathedral: free entry (source: helsinginkirkot.fi, verified July 2026) · Duration: 1 hour
3
Temppeliaukio Church (the church in the rock)
A church carved into solid rock, with a copper dome and exceptional acoustics.
Temppeliaukio Church, known as 'the Rock Church', is one of the most original works in Helsinki and a very popular visit. Opened in 1969 and designed by the brothers Timo and Tuomo Suomalainen, it is literally excavated into a granite outcrop in the middle of the Töölö district: the walls are bare rock and the enormous copper dome, almost 24 metres across, lets in natural light through a ring of skylights. The result is a plain, bright and surprisingly warm space, with magnificent acoustics that make it one of the city's most valued concert halls: it is common to come across rehearsals or classical music recitals. It is a working Lutheran church, so it may close for services or events. It is a short but memorable stop, a perfect example of modern Finnish architecture integrating nature and design. Sitting inside for a while in silence, with the light falling on the rock, is an experience of its own. Getting there: in the Töölö district, a short walk from the centre; buses and tram nearby. Best time: any day; check the opening hours, as it closes for services and concerts. Tips: there is a modest entry fee; come outside group hours to enjoy the acoustics. Combine it with a walk through Töölö and along Mannerheimintie avenue.
ℹ️ Distance: Töölö district, 15 min on foot from the centre · Best time: Any day; check hours (closes for services/concerts) · Entry: Adults approx. 8 € (children free); may close for services and concerts (source: temppeliaukionkirkko.fi, verified July 2026) · Duration: 30 to 45 minutes

Market Square and covered market (Kauppatori and Vanha Kauppahalli)
The market by the harbour and the historic covered market, to try Finnish flavours.
The Market Square (Kauppatori), on the harbour square, is one of the liveliest spots in Helsinki. Out in the open, next to the sea and facing the Suomenlinna ferry, it brings together stalls of seasonal fruit and vegetables, crafts, and above all Finnish street food: freshly fried fish, salmon, herring, salmon soup (lohikeitto), buns and, in season, tasty reindeer meat. It is the ideal place to eat on the go while watching the boats, though the prices are tourist prices. A few steps away is the Vanha Kauppahalli covered market ('the old market hall'), from 1889, a gem of brick and timber where Finns do their gourmet shopping: smoked fish, cheeses, reindeer cured meats, breads, sweets and small cafés where you can sit down to try salmon soup or a coffee with a cardamom bun. It is warm, elegant and perfect for a cold or rainy day. Together, the open-air market and the covered one are the best introduction to northern flavours: Baltic fish, forest berries (bilberries, cloudberries), mushrooms and seasonal produce. Getting there: at the harbour, next to Senate Square; trams 2 and 4. Best time: in the morning, when it is busiest; summer for the open-air atmosphere. Tips: the covered market gives you better price and quality than the tourist stalls outside. Try the lohikeitto (salmon soup). The Hakaniemi market is also nearby.
ℹ️ Distance: Harbour / Senate Square (centre); trams 2 and 4 · Best time: Morning; summer for the open-air market · Entry: Free; you pay for what you eat (a street food dish approx. 10–18 €) (source: visithelsinki.fi, verified July 2026) · Duration: 1 to 2 hours
5
Design District and design museums
The district of shops, studios and museums that made Helsinki famous as a design capital.
Helsinki is one of the world's design capitals (officially so in 2012), and the Design District is the best way to feel it. It is an area of some 25 streets south of the centre (around the Punavuori and Kaartinkaupunki districts) packed with hundreds of design shops, boutiques, architects' studios, galleries, antique dealers, cafés and workshops. This is home to the brands that made Finnish style famous: Marimekko prints, Iittala glassware, Arabia ceramics and a host of independent designers. The district is rounded off by the Design Museum (Designmuseo), which runs through the history of Finnish design — from Alvar Aalto's glass to the everyday objects that conquered the world — and the nearby Museum of Finnish Architecture. It is a perfect route for anyone who enjoys thoughtful shops, object design and the mix of function and beauty that characterises Finland. Walking it also means discovering the everyday, creative Helsinki: speciality coffee shops, bookshops, fashionable restaurants and a very lively young scene, away from the monumental circuits. Getting there: south of the centre (Punavuori, Design District); on foot or by tram. Best time: daytime, with the shops open (note: many close on Sundays). Tips: ask for the Design District map at the tourist office; combine the shops with the Designmuseo. Many businesses close early and on Sundays.
ℹ️ Distance: Punavuori and Kaartinkaupunki districts, south of the centre · Best time: Weekdays (many shops close on Sundays) · Entry: Walking the district is free; Design Museum adults approx. 15 € (source: designmuseum.fi, verified July 2026) · Duration: Half a day
6
Public saunas by the sea (Löyly and Allas Sea Pool)
The Finnish experience par excellence: a sauna facing the Baltic and a dip in the sea.
In Finland the sauna is not a luxury: it is an essential part of life, almost a ritual, and in Helsinki you can experience it at several modern public saunas by the sea. The most famous is Löyly, a spectacular designer timber building on the Hernesaari shore, with wood-fired saunas, terraces over the Baltic and the chance to take a dip in the sea (freezing, even in winter) between sessions. It is so beautiful that it has become an architectural icon. Another central and very popular option is Allas Sea Pool, next to the harbour and the SkyWheel, with saunas and seawater pools (one heated and one at Baltic temperature) and views of the cathedral. For something more traditional and local there is the historic Kotiharjun public sauna, from 1928, the last wood-fired public sauna in Helsinki, which keeps the old atmosphere. Trying the sauna — heating up, going out to cool off in the air or the sea, and repeating — is the best way to understand Finnish culture, listed by Unesco as Intangible Cultural Heritage. It is a relaxing plan you can enjoy in any season, and it is especially magical in winter. Getting there: Löyly in Hernesaari (tram plus a walk, or bus); Allas next to the Market Square. Best time: all year; in winter the contrast with the frozen sea is the ultimate experience. Tips: book Löyly ahead in summer and at weekends; bring a swimsuit and towel (or rent one). Check whether sessions are mixed or separated.
ℹ️ Distance: Löyly in Hernesaari; Allas Sea Pool next to the Market Square (centre) · Best time: All year; winter for the sauna–frozen sea contrast · Entry: Löyly approx. 23 € (2 h of sauna); Allas Sea Pool approx. 16 € for adults (source: loylyhelsinki.fi / allasseapool.fi, verified July 2026) · Duration: 1.5 to 2.5 hours
7
Oodi, the central library, and the Parliament district
The most modern library in Europe, a symbol of egalitarian Finland, facing Parliament.
The Oodi Central Library, opened in 2018 opposite Parliament, is much more than a library: it is a symbol of the Finland that bets on education, equality and quality public spaces. The building, of curved timber, glass and steel, was voted the best public library in the world. Its top floor, the 'book cloud', is a bright, quiet space with panoramic views; but downstairs there are recording studios, 3D printers, sewing machines, work rooms and games rooms, all free for anyone to use. Oodi embodies the Finnish idea that knowledge and technology should be within everyone's reach, at no cost. Going in, even if you do not read a book, is an experience of how Finland understands public services and wellbeing. It sits in Helsinki's civic heart, facing the Parliament building (Eduskuntatalo), next to the music centre (Musiikkitalo), the Kiasma Museum of Contemporary Art and the National Museum of Finland, a good place to group several cultural visits. Getting there: next to the central station and Kansalaistori square; on foot. Best time: any day (it opens almost every day, with long hours). Tips: entry is free; go up to the third floor for the views. Combine it with Kiasma and the National Museum, very close by.
ℹ️ Distance: Centre, next to the central station and Parliament · Best time: Any day; long opening hours · Entry: Free (source: oodihelsinki.fi, verified July 2026) · Duration: 45 min to 1.5 hours

Seurasaari island park and open-air museum
A wooded island with historic houses from all over Finland, linked to the centre by a bridge.
Seurasaari is a green, wooded island a short distance from the centre, joined to the mainland by a wooden footbridge, combining nature and culture. It is home to the Seurasaari Open-Air Museum, founded in 1909, which brings together houses, farms, wooden churches, mills and barns moved from every region of Finland and rebuilt to show how people lived in the Finnish countryside between the 18th and 20th centuries. In summer there are guides in traditional dress who bring the old trades to life. Beyond the museum, the island is a huge park for walking among pines and birches, with trails along the sea, curious squirrels that come up to people and birds everywhere. It is the place where many Helsinki residents celebrate Midsummer (Juhannus) with bonfires by the water, one of the best loved moments of the Finnish summer. It is a calm and very photogenic plan, ideal for switching off from the city centre and breathing in the forest atmosphere that wraps around all of Finland, without leaving town. Getting there: on bus 24 from the centre to the Seurasaari bridge. Best time: summer (museum open and Juhannus bonfires); the island can be walked all year. Tips: walking the island is free; you only pay for the open-air museum. Bring something to snack on and enjoy the forest by the sea.
ℹ️ Distance: Northwest of the centre; bus 24 to the bridge · Best time: Summer (museum open, Juhannus bonfires) · Entry: The island is free; Open-Air Museum adults approx. 12 €, summer season (source: kansallismuseo.fi, verified July 2026) · Duration: 2 to 4 hours

📖 History of Helsinki

Origins, formation and what the sources say.

A port to compete with Tallinn (1550)

Helsinki was born of a political decision. In 1550, king Gustav Vasa of Sweden — the same dynasty that had won Sweden's independence from Denmark — founded a new port town at the mouth of the Vantaa river, on the south coast of what is now Finland, then part of the Swedish kingdom. His aim was clear: to create a trading centre that could compete with prosperous Reval (today's Tallinn, in Estonia), on the other side of the Gulf of Finland, dominated by the Hanseatic League. To populate it, the king ordered merchants from several Finnish towns to be moved there by force.

The gamble did not pay off. For more than two centuries, Helsingfors (the town's Swedish name) was a small, poor place, often struck by fires, famines and outbreaks of plague. Its original harbour was too shallow, so around 1640 the town moved to its present site, on the Vironniemi peninsula, better suited to the job. Even so, it remained a modest place, completely overshadowed by Turku (Åbo), the old capital and home to the country's only university, in the southwest.

Helsinki's fortunes began to change because of its strategic and military value. In the 18th century, the rivalry between Sweden and tsarist Russia turned the Gulf of Finland into a hot frontier, and that tension would give the little town its first great monument.

Sveaborg, the fortress on the sea (1748)

After wars lost against Russia, Sweden decided to armour its eastern border. In 1748 work began on a gigantic sea fortress on a group of islands at the entrance to Helsinki harbour: Sveaborg ('the Swedish fortress'), directed by the officer Augustin Ehrensvärd. It was one of the greatest works of military engineering of its time, funded in part by French subsidies, and came to be nicknamed 'the Gibraltar of the North'. Thousands of soldiers and workers settled in the area, and Helsinki grew for the first time in its shadow, turned into a military base.

The fortress, however, would meet a humiliating end. During the Finnish War (1808-1809), in which Russia invaded the country, Sveaborg surrendered to the Russians in 1808 with barely a fight, after a siege and in circumstances historians still argue about. With its fall, all of Finland passed into the tsar's hands.

The Russians renamed the fortress Viapori and kept it as a naval base for more than a century. Only with Finnish independence in 1917 did it pass to the new country, which gave it its present name in 1918, Suomenlinna ('the castle of Finland'). Today, listed as a Unesco World Heritage Site, it is one of the city's great attractions and living evidence of the centuries when Helsinki was, above all, a stronghold fought over by empires.

The imperial capital: Engel and the white city (1812)

The Finnish War changed everything. In 1809, Sweden ceded Finland to Russia, and the country became the Grand Duchy of Finland, an autonomous state under the sovereignty of the tsar, who also held the title of Grand Duke. It was a surprisingly broad autonomy: Finland kept its laws, its Lutheran religion and an administration of its own. And in 1812, tsar Alexander I took a historic decision: to move the capital from Turku to Helsinki.

The reasons were strategic. Turku was too close to Sweden and too far from Saint Petersburg, the Russian capital; Helsinki, by contrast, was a step away from the imperial metropolis and under the protection of the Sveaborg fortress. But little Helsinki, which had also been devastated by a great fire in 1808, did not look like a capital. The tsar commissioned its reconstruction from scratch on a monumental plan.

The German architect Carl Ludvig Engel designed the new centre in an imposing neoclassical (Empire) style inspired by Saint Petersburg, organised around Senate Square (Senaatintori): the white Lutheran cathedral, the Senate palace and the main university building, the university having moved from Turku to Helsinki in 1828. So was born the 'white city of the north', a planned, elegant capital and a symbol of Finland's new status. Over the 19th century, Helsinki grew fast, became the country's political and cultural centre and was the stage on which Finnish nationalism germinated, with figures such as Elias Lönnrot, compiler of the epic poem Kalevala, and the poet Runeberg.

Independence and civil war (1917-1918)

The 20th century began in tension. In the late 19th and early 20th centuries, Russia tried to cut back Finnish autonomy in a process of 'Russification' that stirred strong national and cultural resistance: this was the golden age of Finnish national romanticism, with the composer Jean Sibelius, the architect Eliel Saarinen and the painter Akseli Gallen-Kallela, and with landmarks such as Helsinki Central Station, a masterpiece of Nordic Art Nouveau.

The Russian Revolution of 1917 opened the door. On 6 December 1917, the Finnish Parliament declared Finland's independence, which Bolshevik Russia recognised shortly afterwards. But the young republic was born in blood: at the start of 1918 a brutal civil war broke out between the 'Reds' (socialist workers, backed by Soviet Russia) and the 'Whites' (the conservative government and the propertied classes, with German help). Helsinki, taken at first by the Reds, was retaken by German troops in April 1918 after hard fighting. The war, short but appalling, left tens of thousands dead — many in prison camps — and a deep wound in Finnish society.

Finland finally consolidated itself as a republic in 1919. Helsinki, the capital, faced the following decades as the centre of a small, independent country determined to build its own identity between the Scandinavian world and the ever-present shadow of its enormous neighbour to the east.

The wars against the USSR and the 1952 Games

The Second World War tested Finland as few things ever have. In 1939, Stalin's Soviet Union, after demanding territory and bases, invaded the country: this was the Winter War (1939-1940), in which a hugely outnumbered Finnish army held out heroically in the snow and checked the Soviets, though Finland ended up ceding Karelia. Helsinki suffered air raids, especially the major attacks of February 1944, though an effective anti-aircraft defence and the use of decoy fires saved the city from the kind of destruction other European capitals suffered.

In the so-called Continuation War (1941-1944), Finland fought the USSR again, this time as a co-belligerent of Nazi Germany, in an attempt to recover the lost territories. With the war ended by an armistice in 1944, Finland achieved something exceptional: it kept its independence and its democracy, unlike the countries of the East that fell under Soviet control, though at the cost of further territorial concessions, heavy war reparations and a cautious foreign policy towards Moscow throughout the Cold War (so-called 'Finlandisation').

The recovery had one bright symbol: in 1952, Helsinki hosted the summer Olympic Games, an enormous success that showed the world a modern, orderly, reborn city. The Olympic Stadium, with its slender tower, is still an emblem. In the decades that followed, Finland transformed itself from a poor agrarian country into one of the most prosperous, best educated and most equal societies in the world.

From the Helsinki Accords to design and technology (20th-21st centuries)

At the height of the Cold War, Helsinki earned a place in world diplomatic history. In 1975 it hosted the Conference on Security and Cooperation in Europe, which culminated in the signing of the Helsinki Final Act, an agreement between the Western and Soviet blocs on borders, security and human rights that marked a milestone in East-West détente. Finland, a neutral country between the two blocs, found in that bridging role an important part of its international identity.

In the last decades of the 20th century and the first of the 21st, Finland and its capital made an extraordinary leap. The country became a world reference in education (its school system is admired across the planet), social welfare and technological innovation: the company Nokia, based in the Helsinki area, came to dominate global mobile telephony, and later a powerful video games scene flourished (Rovio, with Angry Birds; Supercell). Helsinki was named World Design Capital in 2012, cementing the fame of Finnish design — Alvar Aalto, Marimekko, Iittala — as one of its great trademarks.

Today Helsinki is a prosperous, green Nordic capital committed to sustainability, with new waterfront districts, an intense cultural life and an everyday relationship with the islands, the forest and the sauna. In 2023, after the Russian invasion of Ukraine, Finland broke with decades of military neutrality and joined NATO, a historic turn that placed Helsinki once again at the centre of European geopolitics. The little town Gustav Vasa founded to compete with Tallinn is today one of the capitals with the best quality of life in the world.

❓ Frequently asked questions

How many days should I spend in Helsinki?+
With 2 or 3 full days you see the essentials: Senate Square and the cathedral, the Market Square and the harbour, the island fortress of Suomenlinna, the Temppeliaukio rock church, the Design District and a sauna by the sea. With 4 or 5 days you can add a trip to Porvoo, a day of islands and saunas, or a ferry getaway to Tallinn (Estonia), only 2 hours away.
How do you pay for public transport in Helsinki?+
With the HSL network (metro, trams, buses, commuter trains and the ferry to Suomenlinna), all on the same zone-based ticket. The easiest way is to tap a contactless bank card on the readers, or use the HSL app. A single ticket for zone AB costs 3.30 € and is valid for 90 minutes; if you travel a lot, the day ticket from 9 € for 1 day is worth it, verified July 2026. The airport is in zone C (ABC ticket).
Is Suomenlinna worth visiting?+
Very much so. It is an 18th-century sea fortress listed as a World Heritage Site, spread over several islands only 15 minutes by ferry from the centre. Walking its walls, tunnels and batteries facing the Baltic is one of the best experiences in Helsinki, and the ferry is included in the normal HSL ticket (3.30 €). Entry to the fortress is free; you only pay for some of the museums inside. Set aside half a day.
When is the best time to visit Helsinki?+
Summer (June to August) is the star season: very long days, with light almost until midnight, terraces, islands, ferries and swimming in the sea; June and July are ideal. May and September are good alternatives with fewer people. Winter is cold and very dark (few hours of daylight), but it has Christmas magic, saunas and snow; bring very warm clothing and non-slip shoes.
Is Helsinki very expensive?+
It is expensive, in line with the Nordic capitals, especially for accommodation, restaurants and alcohol, though slightly less so than Oslo or Stockholm. To keep costs down: make the most of the midday menu (lounas), much cheaper than dinner; eat at the covered markets; tap water is drinkable and excellent; many museums are free for under-18s and several sites (Senate Square, the cathedral, Oodi, Seurasaari) charge no entry.
Do I need to book the sauna or the ferry to Tallinn?+
The Suomenlinna ferry needs no booking (it goes with the HSL ticket). Design saunas such as Löyly are worth booking online in summer and at weekends, because they fill up. The ferry to Tallinn is worth booking ahead for a better price, especially if you want to go and come back in the same day; it is a very popular and highly recommended excursion.
