When planning a trip to Helsinki, Finland, most travelers focus on the city’s beautiful architecture, vibrant design districts, and bustling waterfront markets. While all of those attractions are certainly worth visiting, one of my favorite experiences during our time in Helsinki was spending a day exploring Suomenlinna.
Located just off the coast of Helsinki, Suomenlinna is a UNESCO World Heritage Site spread across several interconnected islands in the Baltic Sea. It is part historical fortress, part residential community, and part peaceful outdoor escape.
If you are planning a Helsinki itinerary and wondering whether Suomenlinna is worth visiting, the answer is absolutely yes. For me, it became one of the highlights of our entire Finland trip.

How to Get to Suomenlinna from Helsinki
One of the things I loved most about visiting Suomenlinna was how easy it was to reach from central Helsinki.
The public ferry departs from Helsinki’s Market Square, known locally as Kauppatori, and takes only about fifteen minutes to reach the island. Ferries run regularly throughout the day, making it one of the easiest day trips you can take in Finland.
The ferry ride itself is part of the experience. As the boat pulls away from Helsinki’s harbor, you are treated to beautiful views of the city’s waterfront, historic churches, and modern skyline. The urban landscape gradually fades into the distance while the scattered islands of the Finnish archipelago begin to appear around you.
Even before arriving at Suomenlinna, I found myself constantly reaching for my camera. The views across the water were stunning, and the journey provided a perfect introduction to Finland’s deep connection with the sea. For such a short ride, it felt surprisingly scenic.
First Impressions of Suomenlinna
The moment we stepped off the ferry, the atmosphere completely changed. Downtown Helsinki feels modern, energetic, and urban. Although it was a cold and gloomy day, Suomenlinna felt quiet, relaxed, and timeless.
Instead of busy streets and crowded attractions, we found winding pathways, historic stone buildings, grassy fields, and centuries-old fortifications overlooking the Baltic Sea. Some parts made it feel like we were in The Lord of the Rings movies.
Many famous attractions throughout Europe can feel crowded and commercialized, especially during peak travel season. Suomenlinna felt different. It was pretty cold when we went at the end of April, and, despite the gloomy weather, the island was full of people walking, enjoying picnics, or simply sitting on the shoreline taking in the ocean views. There was no rush and no pressure to move quickly from one attraction to the next. The island naturally encourages visitors to slow down and enjoy the surroundings.
The Fascinating History of Suomenlinna
Even if you are not typically interested in history, it is impossible not to appreciate the significance of Suomenlinna.
Construction of the fortress began in 1748 when Finland was still part of the Kingdom of Sweden. The fortress was designed to defend Sweden’s eastern territories against Russian expansion in the Baltic region. Over time, it became one of the largest sea fortresses in the world.
Throughout its history, Suomenlinna has been controlled by Sweden, Russia, and eventually Finland. Today, it remains one of the country’s most important historical landmarks and attracts visitors from around the globe.
What makes the experience particularly special is that the history is not confined to a museum building. It is integrated into the landscape itself. The massive stone walls, military structures, tunnels, cannons, and preserved buildings are all part of the environment. Rather than simply reading about history, visitors have the opportunity to walk through it and experience it firsthand.
Exploring the Fortress on Foot
The best way to experience Suomenlinna is simply by wandering and allowing yourself to explore.
We followed the King’s Gate route (you can talk with the tourism office when you are there for more information) and spent several hours walking around without a strict plan, and honestly, I think that is exactly how the island should be enjoyed. Walking paths connect the various sections of the fortress and lead visitors past historic buildings, old military installations, hidden courtyards, scenic viewpoints, and quiet waterfront areas.
One of my favorite moments was standing on top of the fortress walls overlooking the Baltic Sea. Seeing the massive stone defenses rise directly from the shoreline made it easy to understand why this location was strategically important for centuries.
As we explored, we encountered old gates, tunnels, and cannons that seemed almost frozen in time.
At several points during our visit, we found ourselves completely alone with only the sounds of the wind and waves nearby. For such a popular attraction, it was surprisingly easy to find peaceful corners away from the main tourist routes.
The Best Views in Suomenlinna
If you enjoy photography, Suomenlinna is a dream destination. Every turn seemed to reveal another postcard-worthy scene. The combination of rugged stone fortifications, bright green grass, colorful wooden buildings, and deep blue water creates some truly spectacular landscapes.
The coastal viewpoints were easily my favorite part of the island. Watching waves crash against the rocky shoreline while ferries and sailboats passed in the distance felt like the perfect Finnish coastal experience.
Unlike many popular tourist destinations where you constantly have to avoid crowds in your pictures, Suomenlinna offers plenty of open spaces and natural scenery that make photography much easier and more enjoyable. Whether you are using a professional camera or simply taking photos with your phone, you will have no shortage of beautiful subjects. Our photos are quite gloomy, but I imagine in the warmer months you get brighter and full-bloom photos!
A Living Community on a Historic Fortress Island
One thing many visitors do not realize is that people actually live on Suomenlinna. Approximately 800 residents call the islands home, adding a unique dimension to what is already one of Finland’s most fascinating historical sites.
As we explored beyond the busiest areas, it was interesting to see how daily life exists alongside centuries-old fortifications. Rather than feeling like a place preserved solely for tourists, Suomenlinna remains a living community where history and modern life intersect.
Where to Stay on Suomenlinna
If you’d like to experience the island after the day-trippers leave, consider spending a night on Suomenlinna. The island offers a handful of accommodations, including guesthouses and apartments, allowing visitors to enjoy the peaceful atmosphere, waterfront views, and historic surroundings long after the last ferry crowds have departed. Staying overnight provides a unique opportunity to experience a quieter side of one of Finland’s most iconic landmarks. While we stayed at the Hilton Helsinki Kalastajatorppa, here are two highly recommended places to stay right on Suomenlinna – which we’d do again if we had the time:
- Seaside Cottage in Suomenlinna Island (great reviews!)
- Hostel Suomenlinna
Lunch at Suomenlinna Brewery
After spending the morning exploring the island, we stopped at Suomenlinna Brewery for lunch. Someone suggested it to us and glad we did it.
Naturally, trying a local Finnish beer felt like an essential part of the experience. The brewery is housed inside one of the island’s historic buildings and offers a warm and welcoming atmosphere that perfectly complements the surrounding fortress environment.
For lunch, Vanessa ordered steak while I ordered yet another bowl of Finnish salmon soup. By this point in the trip, I had fully accepted that I was completely obsessed with Finnish salmon soup. And honestly, I have no regrets.
Once again, the salmon was incredibly fresh, the broth was rich and flavorful, and the dish perfectly showcased the quality of Finnish seafood. It was comforting, satisfying, and exactly what I wanted after several hours of walking around the island.
Paired with a locally brewed beer, it ended up being one of my favorite meals during our time in Helsinki. Sometimes the simplest meals become the most memorable travel experiences, and this was definitely one of them.
It’s important to note that this brewery was one of the only places to eat while on the island in April, I believe a couple others were open throughout the island. There is much more available in terms of cafes, food, and drinks in the warmer months.
Why Suomenlinna Was One of My Favorite Places in Finland
Looking back on our trip, what made Suomenlinna so special was not any single attraction. It was the overall experience.
The short ferry ride, the fascinating history, the beautiful scenery, the peaceful atmosphere, and the freedom to explore at our own pace all combined to create one of the most enjoyable days of our journey through Finland.
It is rare to find a destination that appeals equally to history lovers, photographers, nature enthusiasts, and casual travelers. Suomenlinna somehow manages to do exactly that.
Whether you are interested in military history, UNESCO World Heritage Sites, scenic walking trails, photography, or simply escaping the city for a few hours, you will find something to appreciate here.
The island offers a balance that many tourist attractions struggle to achieve. It is educational without feeling overwhelming, beautiful without feeling artificial, and popular without feeling overcrowded.
Tips for Visiting Suomenlinna
If you are planning your own visit, here are a few tips that can help make the most of your experience:
- Allow at least half a day to explore the island.
- Wear comfortable walking shoes since there is a lot of ground to cover.
- Make sure your phone is charged so you can take lots of photos (or bring a fancy camera!)
- During good weather if possible, as much of the experience takes place outdoors.
- Take time to wander beyond the main tourist paths to discover quieter areas.
- Consider stopping for lunch at one of the island’s restaurants or cafés, but check what is open when you get there.
- Do not rush. The charm of Suomenlinna comes from exploring slowly.
Final Thoughts on Visiting Suomenlinna

For me, it became one of the highlights of our entire Helsinki adventure. Between the centuries old fortress walls, stunning Baltic Sea views, quiet walking paths, fascinating history, and unforgettable salmon soup at Suomenlinna Brewery, it was the perfect way to spend a day.
Sometimes the best travel experiences are not the busiest attractions or the most famous landmarks. They are the places that allow you to slow down, explore freely, and genuinely connect with your surroundings. Suomenlinna was exactly that.
