Helsinki packs a surprising amount into a compact, walkable city centre of roughly 600,000 residents (1.5 million in the metro area). You can see the main sights in 2 full days, but 4 to 5 days lets you explore the islands, neighbourhoods, and sauna culture at a relaxed pace. The city’s design-forward sensibility, maritime setting, and unabashed embrace of sauna make it feel distinct from other Nordic capitals. Here are the best things to do in Helsinki, from the obvious landmarks to the local-only experiences. Check our Helsinki weather by month for more information.
Things to Do in Helsinki: Iconic Landmarks and Sights
Suomenlinna Sea Fortress
Suomenlinna is a UNESCO World Heritage sea fortress spread across six islands, built by Sweden in 1748 when Finland was part of the Swedish kingdom. The HSL ferry from Market Square (Kauppatori) takes 15 minutes and runs year-round; it’s included in the standard HSL day ticket, currently 9 euros for a 24-hour AB-zone pass. The fortress itself is free to explore, with museums (the Suomenlinna Museum, Military Museum, Ehrensvard Museum, and a submarine called Vesikko) charging separate entry of 5 to 12 euros each. Budget at least 3 to 4 hours, more if you plan to eat at one of the island’s restaurants or breweries. The King’s Gate drawbridge and the dry dock are the most photogenic spots. In summer, the island hosts open-air theatre, and the swimming beach is popular with locals. In winter, the windswept fortress takes on a stark Baltic beauty, but most museums close or reduce hours from October through April. The ferry runs approximately every 20 to 30 minutes in summer and every 40 to 60 minutes in winter. Check our best time to visit Helsinki for more information.
Helsinki Cathedral and Senate Square
The gleaming white neoclassical Helsinki Cathedral dominates Senate Square from the top of a broad staircase that has become the city’s default meeting point and photo backdrop. Designed by Carl Ludvig Engel and completed in 1852, it was originally built as a tribute to Tsar Nicholas I of Russia (Finland was a Grand Duchy of the Russian Empire from 1809 to 1917). The cathedral is free to enter, open daily from 9 AM to 6 PM, with shorter hours in winter, typically 10 AM to 4 PM. The interior is more austere than the dramatic exterior suggests: a deliberate Lutheran rejection of Catholic ornamentation. The crypt underneath hosts exhibitions and a cafe. Senate Square itself holds the Government Palace, the University of Helsinki’s main building, and the National Library, all by Engel. The Alexander II statue in the centre of the square was erected in 1894. Every morning at 10 AM, tour groups form here. Come before 9:30 AM for empty square photos. Check our Helsinki events and festivals calendar for more information.
Temppeliaukio Church (Rock Church)
The Temppeliaukio Church, universally known as the Rock Church, was excavated directly into solid granite in 1969. The design by brothers Timo and Tuomo Suomalainen features a copper dome 13 metres above the floor, supported by 180 window panes that let in natural light. The rough-hewn rock walls create exceptional acoustics, and the church doubles as a concert venue. Entry is 5 euros for adults, free for children under 18. Hours vary seasonally but are typically 10 AM to 5 PM daily, with reduced hours and closures during services and events. It’s in the Toolo neighbourhood, a 15-minute walk from the Central Railway Station or a short tram ride on lines 2 or 4. Arrive at opening time to avoid the tour groups that descend by 11 AM. This is one of the most visited attractions in Finland, receiving over 600,000 visitors annually. If a service or concert is underway, you’ll be asked to wait outside. Check our Helsinki neighborhoods guide for more information.
Loyly Public Sauna
Loyly is Helsinki’s most architecturally striking public sauna, a sculptural wood-clad complex on the Hernesaari waterfront designed by Avanto Architects. It opened in 2016 and quickly became a symbol of modern Helsinki. The sauna area includes two wood-heated saunas (one standard, one smoke sauna) and direct access to the Baltic Sea for cold plunges year-round: yes, Finns cut holes in the ice in winter. Entry is 19 euros for 2 hours and includes a towel and seat cover. The complex also has a popular restaurant and terrace, which you can access without paying the sauna entry fee. It’s a 30-minute walk from the city centre or a 10-minute bus ride on lines 14 or 17 from Kamppi. Reservations are not required for the sauna, but summer weekends can have a 30 to 45-minute wait. Go on a weekday morning for the quietest experience. Check our where to stay in Helsinki for more information.
Things to Do in Helsinki: Museums and Culture
Ateneum Art Museum
The Ateneum is the home of Finnish art, part of the Finnish National Gallery alongside Kiasma and the Sinebrychoff Art Museum. The collection spans from the 18th century to the 1950s, with the strongest concentration on the Finnish Golden Age from 1880 to 1910: works by Akseli Gallen-Kallela, Albert Edelfelt, Helene Schjerfbeck, and Hugo Simberg, whose ‘The Wounded Angel’ is the museum’s most famous single painting. Temporary exhibitions draw major international names. Entry is 20 euros for adults, free for under-18s. Open Tuesday and Friday 10 AM to 6 PM, Wednesday and Thursday 10 AM to 8 PM, Saturday and Sunday 10 AM to 5 PM. Closed Mondays. The museum is on the south side of the Central Railway Station square. Budget 1.5 to 2 hours. Check our Helsinki travel tips and FAQ for more information.
Kiasma Museum of Contemporary Art
Kiasma, designed by American architect Steven Holl and opened in 1998, is Helsinki’s contemporary art museum with a shifting exhibition programme of Finnish and international contemporary art across five floors of curvilinear spaces. Entry is 20 euros for adults, free for under-18s. Open Tuesday to Friday 10 AM to 6 PM, until 8:30 PM on Fridays, Saturday and Sunday 10 AM to 5 PM. Closed Mondays. It’s directly behind the Parliament House, a 5-minute walk from the Central Railway Station. The on-site cafe is good for a quick lunch. Kiasma also runs the Kiasma Theatre, which programmes experimental performance and film.
Seurasaari Open-Air Museum
Seurasaari is an island open-air museum 4 km northwest of the city centre, with 87 historic buildings relocated from across Finland to represent rural life from the 18th to 20th centuries. Buildings include farmhouses, manor houses, a church from 1686, and windmills. Guides in traditional dress demonstrate crafts. Entry is 12 euros for adults and the museum is open from late May through mid-September, typically 11 AM to 5 PM with extended hours in high summer. The island itself is a public park and free to walk around year-round; the buildings are only open and staffed during the summer season. The island is also home to a friendly population of semi-tame red squirrels. Bus 24 from the city centre (Erottaja or Kamppi) takes about 15 minutes. Midsummer Eve in late June is the biggest event here: traditional bonfires, folk dancing, and a wedding ceremony in the 1686 church.
Things to Do in Helsinki: Neighbourhoods and Streets
Design District and Punavuori
The Design District is a loosely defined area covering Punavuori, Kaartinkaupunki, and parts of Ullanlinna, with about 200 design shops, galleries, antique stores, fashion boutiques, and design-focused cafes. Walking the streets between Iso Roobertinkatu, Bulevardi, and the waterfront is the core experience. Key stops include the Design Museum at Korkeavuorenkatu 23 (15 euros entry), the Iittala and Arabia flagship stores, Marimekko’s headquarters and factory outlet on Kirvesmiehenkatu (20 minutes by tram from the centre), and the Artek store carrying Alvar Aalto’s furniture brand. Most shops open around 10 to 11 AM and close at 6 PM on weekdays, 4 to 5 PM on Saturdays, with many closed Sundays. The area is especially good for vintage Finnish design from the 1950s to 1970s: glassware, ceramics, and furniture. Budget 2 to 3 hours to browse properly.
Kallio Neighbourhood
Kallio, northeast of the city centre across the Pitkasilta (Long Bridge), is Helsinki’s former working-class district turned bohemian heartland. It’s the most densely populated neighbourhood in Finland and the centre of Helsinki’s bar, cafe, live music, and vintage shopping scenes. Key streets are Helsinginkatu, Fleminginkatu, and Vaasankatu. Hakaniemi Market Hall at the southern edge of Kallio (Hameentie 1, open Monday to Friday 8 AM to 6 PM, Saturday 8 AM to 4 PM) serves traditional Finnish foods on the ground floor and crafts upstairs. The Kallio Church, a granite art nouveau church from 1912, dominates the skyline. Bear Park (Karhupuisto) is the neighbourhood’s central green space and gathering spot. For the authentic Kallio experience, get a pulla (cardamom bun) and coffee at Kahvila Savy on Aleksis Kiven katu, browse the vintage shops on Vaasankatu, and end the day with a sauna at Kotiharjun or Arla.
Things to Do in Helsinki: Day Trips and Nature
Nuuksio National Park
Nuuksio National Park is 30 km northwest of Helsinki in Espoo, reachable in about 45 minutes by public transport: HSL bus 245 from Espoo Centre station, which is on the commuter train line from Helsinki Central. The park covers 45 square kilometres of pristine boreal forest, lakes, and granite outcrops. Trails range from easy 2 km loops to a 30 km multi-day route, all well-marked. The Finnish Nature Centre Haltia at the park entrance (open Tuesday to Sunday 10 AM to 5 PM, closed Mondays) provides maps, trail advice, and exhibitions on Finnish nature. In summer, you can swim in the lakes and pick wild berries: blueberries in July and August, lingonberries in September. In winter, there are marked cross-country ski trails and snowshoe routes. Entry is free; no admission fees. Bring water and food, as there’s only a cafe at Haltia. The park is busiest on summer weekends; go midweek for solitude.
Porvoo Day Trip
Porvoo is Finland’s second-oldest city, 50 km east of Helsinki, with a famously photogenic old town of cobblestone streets and red-ochre wooden warehouses along the Porvoonjoki River. Buses depart from Helsinki’s Kamppi terminal roughly every 30 minutes, taking 55 to 65 minutes. Onnibus or the regular coach service tickets start from 10 euros each way when booked online. The Porvoo Cathedral dates to the 15th century. The old town has about 200 wooden buildings, most serving as shops, galleries, and cafes. The red warehouses on the riverbank, originally built in the 18th century to store goods awaiting customs inspection, are the most photographed spot. Brunberg, Finland’s oldest confectionery founded in 1871, has a factory shop selling their famous chocolate kisses. Budget 4 to 5 hours for a relaxed half-day trip. Best in summer (May to September) when all shops and cafes are open; in winter, many businesses reduce hours or close entirely.
Things to Do in Helsinki: Food and Drink
Old Market Hall (Vanha Kauppahalli)
The Old Market Hall on the South Harbour at Etelaranta, next to Market Square, has been operating since 1889 and is Helsinki’s best single-stop food experience. Inside the brick building, about 25 stalls sell Finnish specialities: smoked salmon and reindeer from E. Eriksson, traditional salmon soup (lohikeitto) from Soup Kitchen at around 9.50 euros for a bowl with bread, Karelian pies from Leipomo Ronttonen, and Finnish cheeses. Open Monday to Saturday 8 AM to 6 PM, with some stalls closing earlier on Saturdays, around 4 PM. It’s more expensive than a supermarket but far cheaper and more interesting than a sit-down restaurant. Get there before noon for the fullest selection. The adjacent Market Square (Kauppatori) has outdoor stalls from roughly April to October selling produce, handicrafts, and street food: fried vendace (muikku) from the orange tents is the move, with a portion costing about 8 to 10 euros.
Finnish Sauna Experience
No visit to Helsinki is complete without a sauna. Finland has 3.3 million saunas for 5.5 million people, and the ritual is integral to Finnish life. Sauna protocol: shower first, enter the sauna at 80 to 100 degrees Celsius, sit on a towel or paper seat cover, throw water on the stones for loyly (steam) when you want more heat, stay as long as comfortable, typically 10 to 15 minutes per round, then cool down outside or with a cold plunge or shower. Repeat the cycle 2 to 3 times. Drink water or beer between rounds. Nudity in gender-segregated saunas is normal and expected; swimsuits are worn in mixed-gender public saunas. The main public saunas in Helsinki: Loyly at 19 euros (modern, waterfront), Allas Sea Pool at 14 euros (Market Square, with pools), Kotiharjun Sauna at 14 euros (traditional, Kallio, bring your own towel), and Sompasauna (free, self-service, community-run, waterfront in Kalasatama, the most authentic and raw option but with no staff or changing rooms).
