15 Must-Do Activities in Helsinki: My Top Picks After 6 Visits!

Helsinki has a unique buzz that sets it apart from other Nordic capitals like Copenhagen, Stockholm, and Oslo. The capital of Finland offers a mix of modern architecture, clean air, and local food that make it a livable and safe destination. During my six visits, I’ve noticed that while tourists are fewer compared to other cities in Northern Europe, the city center remains vibrant. It’s a place where you can enjoy walking by iconic spots like the Cathedral or riding the SkyWheel for a breathtaking view of the city. The experience here is much more than just sightseeing—it’s about the welcoming vibe that the city offers, whether you’re exploring on your own or with company.

Helsinki’s charm also lies in its balance between history and modern life. Learning about the 16th century founding by the King of Sweden, the plague of 1710, and the time when Russia annexed the area adds depth to your guide-style visiting. The weather here can be perplexing, especially the dark winters, but that just adds to the happiest world rankings that I can truly understand after spending time in this compact city. Transportation is easy, and I loved exploring the outdoors and enjoying the water during both winter and summer days. Even if you’re just sipping coffee at a cafe or sitting in one of the many green spots, Helsinki has a way of making you feel like you’ve discovered a hidden destination in the heart of Scandinavia.

Take a Free Walking Tour

One of the best ways to explore Helsinki is by taking a free walking tour. I’ve joined several tours, including Green Cap Tours and Free Tour Helsinki with Red Umbrella Tours. These tours typically last 1.5-2 hours and offer a great introduction to the city. A local expert guides you through iconic spots like Senate Square, cathedrals, and the bustling Market Square, while sharing interesting stories, history, and culture. Walking around, I learned about the city’s founding in 1550 by Swedish King King Gustav I, and how it was once part of the Swedish empire before being conquered by the Russian empire in 1808. It remained under Russian rule until independence in 1917, blending modern charm with centuries of layered stories.

Even though there are paid options like a hop-on, hop-off bus tour, I always prefer the free tours because they offer a relaxed way to explore and allow you to meet a friendly guide who’s happy to answer all your questions. It’s also a great way to get oriented and discover hidden places you might not find on your own. I always book online in advance and make sure to leave a tip to thank the guide for the wonderful experience, especially when I’m just starting my visit.

Visit Suomenlinna

A must-visit in Helsinki is taking the ferry to Suomenlinna, a UNESCO World Heritage Site that holds a significant place in Finnish history. This historic fortress spreads across eight islands and was built during Swedish rule.

While some military areas are still in use, much of the site is now open to the public. I remember walking around the quiet paths in the snow, experiencing a true winter experience, and then returning in the warmer months to enjoy a relaxed picnic with friends. It’s a place where history and leisure come together in a truly remarkable spot.

How To Get To Suomenlinna

To get to Suomenlinna from Helsinki, I always head to Kauppatori and catch the ferry. The ride feels more like a mini-adventure than just travel.

You can easily buy a public transport ticket through the HSL app on iOS or Android, and the journey takes about 15 minutes, offering lovely views of Finland and its nearby islands. The ferry runs year-round, but the winter schedule is more limited, so I always check the times and dates in advance to plan smoothly.

Visit the Post Museum

One of the more unexpected spots I enjoyed in Helsinki was the Post Museum, which explores the history of postal service in Finland. I thought it would be boring, but it turned out to be surprisingly interesting. The exhibits take you through the history of the mail service, from ships and sleds in the 1600s to the modern-day system.

There are also relics, galleries, and even short films that show how delivery worked in a harsh environment and sparsely populated land. It’s a fun, educational, and accessible museum located at Alaverstaanraitti 5, and with an admission of 15 EUR, it’s a hidden gem worth the visit. The museum is open Monday-Friday from 11am-7pm and Saturday-Sunday from 11am-5pm.

Enjoy A Sauna Visit

In Finland, a sauna visit is more than just for relaxation; it’s almost a part of the country’s logic. In Helsinki, you can visit places like Löyly, which offers a Finnish experience with modern facilities. You can even swim in the Baltic Sea—I went in the summer, and the water was still freezing cold.

After a few rounds of hot and cold exposure (almost like that Katy Perry song), I highly recommend grabbing food at the restaurant there. For a more traditional experience, I also visited Kotiharjun sauna in Kallio, which is famous for its glowing SAUNA sign, making it feel like stepping into a long-standing tradition.

Visit Helsinki’s Many Parks

One of the best ways to experience Helsinki is by visiting its parks, especially during the summer evening light. I love spending time in places like Hesperianpuisto and Töölönlahdenpuisto, where the beautiful surroundings and paths make for a relaxing walk.

The combination of islands and greenery makes these parks feel calming and peaceful. Kaivopuisto, located near the water, is another park that is stunning year-round. While it’s less green in the winter, the sight of the park covered in snow is always worth the visit, reminding me of how great Helsinki is in every season.

Attend a Candlelight Concert

One of the most unique experiences in Helsinki is attending the Candlelight Concerts, a series of original music performances by local musicians in special venues around the city. The atmosphere is made even more magical with the space being illuminated by thousands of candles, creating a truly interesting and unforgettable experience.

I enjoyed listening to live classical music from famous artists like Vivaldi and Mozart, while also exploring other music genres such as jazz, soul, opera, contemporary, and even movie soundtracks, all performed by classical musicians and string quartets. The experience is enhanced by a multi-sensory experience, with ballet dancers and aerial performers adding creative elements. It’s always great to support local artists, and checking their website for upcoming events has become part of my travel routine.

Relax in Sinebrychoff Park

If you’re looking to slow down in Helsinki, Sinebrychoff Park is a great place to relax. This small park, dating back to the 18th century, was once a private garden owned by a Russian businessman before becoming a public park in the 1960s.

It’s now a popular spot for picnics, relaxing, and seasonal events. In the winter, people enjoy sledding, while in the summer, the park is full of locals enjoying the sunshine. I love grabbing a snack from the nearby cafes, lounging, and watching the day go by in a calm yet lively atmosphere.

Sample Helsinki’s Many Great Cafés

During my visits to Helsinki, I quickly discovered that its café scene is one of the city’s best-kept secrets. Even in the dark winters of December, January, and February, the Finns know how to make the most of their cozy indoor spaces while enjoying outdoor activities like winter walks. One of my favorite spots was RAMS Roasters, a charming café in the Finnish capital, where I had the best cup of coffee with Danny Maiorca.

The atmosphere there felt very much like the cozy, laid-back cafés of Copenhagen, with cinnamon buns and savory treats adding to the experience. If you want something with a unique view, Café Regatta is a must-visit. This classic spot has a beautiful waterfront view, and its cozy red hut with outdoor seating is perfect for a relaxing day in the summer. There, you can also grill sausages by the water while enjoying a cup of coffee or one of their delicious pastries. And for those looking for more great options, Levain offers solid choices that will make you feel right at home. Helsinki’s cafés truly offer a delightful blend of indoor comfort and outdoor charm, making it one of the most memorable parts of the city.

Check Out The City From Above At Ateljee Sky Bar

One of the best ways to explore Helsinki from above is to visit Ateljee Sky Bar, located on top of Hotel Torni. This spot offers a breathtaking view of Kallio and the city center, making it a must for anyone who wants to experience the city from a unique perspective.

The bar opens daily at noon, and while it can be a bit expensive, the drinks you purchase also act as an entry fee. It’s easy to find the place at Yrjönkatu 26, 00100, and despite some of my gripes about the limited high-up viewpoints in the city, I truly appreciate this one. Whether or not you’re staying at the hotel, this place is a fantastic choice to enjoy a drink and the view of Helsinki from a higher vantage point.

Explore the National Museum of Finland

If you’re a history buff, the National Museum of Finland is a must-see in Helsinki. The museum houses a large collection of Finnish artifacts that span from the Stone Age to the present. You’ll find fascinating items like jewelry, coins, tools, and weapons, each telling a part of Finland’s history.

Unlike some museums that can be disappointing or underfunded, this museum offers a comprehensive collection that provides a rich cultural history of Finland, perfect for those looking to learn about Finnish folk culture and the Finno-Ugric people. Along with its permanent collections, the museum regularly features rotating pop-up exhibits, workshops, and tours for a complete overview of Finland’s past. You can find it at Mannerheimintie 34, and it’s open daily from 11am-6pm, with extended hours until 8pm on Wednesdays. Admission is between 14-18 EUR, but it’s free every Friday from 4pm-6pm. The museum is closed on Mondays during the winter months.

Visit a cathedral

Visiting Helsinki wouldn’t be complete without exploring its grand cathedrals. The Helsinki Cathedral, located in Senate Square in the city center, is a Finnish Evangelical Lutheran church known for its stunning green dome and granite staircase. Built between 1830 and 1852 as a tribute to Tsar Nicholas I of Russia, this church has become a symbol of the city. Its Neoclassical design and the statues of the Twelve Apostles make it stand out, while the humble Lutheran design inside offers a peaceful, memorable experience.

Not far from there is the Uspenski Cathedral, located near the south harbor. This ornate, red brick cathedral is the largest orthodox church in Western Europe, and its lavish interior is absolutely stunning. For something different, check out the Temppeliaukion Church in the Töölö neighborhood. This round church, built into rough stone walls with a shiny copper dome, offers excellent acoustics and serves as both a working church and a concert venue, giving you a unique way to enjoy Helsinki’s spiritual and architectural heritage.

Hang out in a library

If you’re a book lover, Helsinki is a dream come true. The city and the whole country have over 700 libraries, and with 5.5 million people, around 65% of Finnish people use a public library at least once per week. As a tourist, you’ll quickly notice how incredible these spaces are.

One must-visit is the National Library of Finland, located just across the street from Helsinki Cathedral, known for its beautiful, symmetrical Neoclassical architecture and iconic rotunda. Another top spot is the Helsinki Central Library Oodi, which opened in late 2018. This famous, new library is a design-forward space, located next to the Helsinki Music Centre and Kiasma Museum of Contemporary Art. It offers sleek design, two cafes, an outdoor terrace, and even flexible spaces you can rent for activities like recording music or cooking a meal. Hanging out here is a unique way to experience Helsinki like a local.

Cozy up in a coffee shop

In Helsinki, there’s no better way to start your day than with a cup of light-roasted filter coffee at one of the city’s many coffee shops. The Finns are known for their love of coffee, and unlike many other countries, they don’t go for espressos or fancy lattes.

Instead, they enjoy several cups per day of filter coffee—in fact, Finnish people drink more coffee per capita than in any other country! Some of the best spots to try include Andante Speciality Coffee, Kaffa Roastery, Rams Roasters, and Robert’s Coffee, which is the most popular and wide-spread local coffee shop chain, even more so than Starbucks. A visit to these cozy spots is a must for any coffee lover in Helsinki.

Embrace Finnish sauna culture

When you visit Helsinki, one of the must-do experiences is embracing the authentic Finnish sauna culture. Having experienced it several times, I can say that the sauna is a deep-rooted part of Finnish life. Whether you’re staying in private hotel apartments or visiting public saunas like Löyly, you’re in for a unique experience. The Gulf of Finland and waterfront locations often add to the charm, especially if you have a chance to relax in the outdoor terrace with views of the Baltic Sea water.

Some of the best spots, like Allas Sea Pool, offer outdoor swimming pools with varying temperatures, so you can alternate between a cold plunge and a soothing sauna. For a more intimate experience, try the SkySauna, a tiny sauna pod located high above the city on the SkyWheel Ferris wheel. You can reserve a time slot for a SkySauna gondola car, where 1-4 people can enjoy the sauna for around €240 per hour. Or, if you’re looking to relax with friends, enjoy a hot tub for up to 10 people. Don’t forget the essential items—towel, shampoo, and a seat cover—all included in the €23 per person sauna experience, which usually lasts 2 hours. Whether it’s the soothing heat or the refreshing plunge, these sauna experiences are an essential part of Helsinki and a perfect way to unwind.
