Suomenlinna, located just off the coast of Helsinki, is a well-known destination, at least by name. However, right next to it lies the lesser-known Vallisaari, an equally fascinating and historically rich island, making it a great day-trip destination in the Helsinki archipelago.
Vallisaari was used for military purposes for a long time and was only opened to the public in 2016. As a result, it has remained largely untouched, boasting lush greenery and a more natural atmosphere compared to its more popular neighbor. Facilities are still somewhat limited, but visitors can find a few cafés and restaurants on the island.
How to get to Vallisaari – Vallisaari ferry
The easiest way to reach Vallisaari is by ferry from Helsinki’s Market Square (Kauppatori), much like traveling to Suomenlinna. However, HSL tickets are not valid for ferries to Vallisaari, so a separate ticket must be purchased. The ferry service is operated by FRS Finland, and tickets can be bought in advance online (e.g., at vallisaari.fi) or at the Market Square ticket booth (round trip: 10,90 €/adult). The ferry ride takes about 20 minutes and offers stunning views of the archipelago. Alternatively, visitors can also arrive by private boat, with a guest marina located at Torpedolahti Bay.
Vallisaari is open to the public only during the summer season, from May to the end of September. During summer, ferries run regularly, making the island easily accessible, but in winter, it is closed to visitors. It is advisable to check the ferry schedules in advance.
One important detail to note is that the return ferry departs from a different location than the arrival point. Ferries from Market Square dock at the Luotsipiha pier in the northern part of the island, while return ferries leave from the Torpedolahti pier, situated between Vallisaari and Kuninkaansaari.
Arriving in a natural paradise
The moment you step onto Vallisaari, you’ll notice a distinct atmosphere—nature here is wilder and more diverse than on many other Helsinki islands. Vallisaari is particularly known for its rich biodiversity, home to rare plants, butterflies, and even bats. The island has remained largely in its natural state, offering a striking contrast to city life.
Even at the ferry dock, you can feel the tranquility of the island. Vallisaari is not a place for rushing; instead, it invites you on an exploration where you can peacefully enjoy the beauty of your surroundings.
Two scenic routes: Aleksanterin kierros & Kuninkaansaaren kierros -Trails
Visitors can only explore Vallisaari along marked trails. The two main trails, Aleksanterin kierros -Trail and Kuninkaansaaren kierros -Trail, are well-marked and easy to follow, leading to all the island’s major sights. Movement outside these designated routes is prohibited due to safety concerns, including unstable structures and remnants of a 1937 explosion, which may have left unexploded ordnance in the terrain. The southern part of Vallisaari is entirely off-limits, with clear signage indicating restricted areas.
Aleksanterin kierros -Trail
Aleksanteri Trail is a 3-kilometer circular route passing through Vallisaari’s most significant sights. The path is easy to walk, though there are some elevation changes, making it suitable for all ages. Key highlights along the trail include:
- Aleksanterin patteri (Aleksanteri Battery) – One of the most impressive historical sites on the island, this massive fortress highlights Vallisaari’s military past. The observation deck offers breathtaking views of the sea, and it’s a great spot to watch cruise ships pass through Kustaanmiekka Strait.
- Pohjolan Gibraltar (Gibraltar of the North) – Another viewpoint with stunning scenery overlooking Kustaanmiekka Strait and Suomenlinna.
- Torpedolahti Bay – An idyllic spot to take a break and admire the landscape. This area has the most services, including several cafés and restaurants, making it a great place to relax and wait for the return ferry. Torpedolahti also has Vallisaari’s guest marina and serves as the gateway to the neighboring Kuninkaansaari.
- Linden Alley – A beautiful, tree-lined path leading towards Aleksanterin patteri.
- Meadows and Ponds – Vallisaari is particularly green, with several meadows and ponds adding to its lush scenery. The largest pond, Vallisaari Pond, is located along the trail. Although it may look inviting on a hot summer day, swimming is prohibited.
Kuninkaansaaren kierros -Trail
Kuninkaansaaren kierros -Trail is slightly shorter (about 2.5 kilometers) but more challenging due to rougher terrain. It starts from Torpedolahti and takes you through one of the quietest and most serene parts of islands. Previously closed to the public, Kuninkaansaari is now an excellent addition to a visit, offering breathtaking landscapes and old military structures.
The most striking feature of Kuninkaansaari is the fortress that extends almost across the entire island. Visitors can explore much of the fortress, and from the side facing Torpedolahti, there are spectacular sea views.
More structures can be found on the hilltop, accessible via a path along the island’s eastern edge, passing by an old bunker sauna and a former transformer station before reaching the summit.
History comes to life on Vallisaari
Vallisaari’s military past is still evident throughout the island. Its old buildings and fortifications tell a story of history and are fascinating to explore. Although some areas are restricted, there is plenty to see for an entire day. The Aleksanteri Battery and Kuninkaansaari Fortress are must-see highlights, complemented by the stunning views found throughout the islands.
Vallisaari is a true gem of the Helsinki archipelago, combining untouched nature, historical fortifications, and a peaceful ambiance. Whether you’re looking to immerse yourself in history, explore the natural landscape, or simply enjoy a relaxing summer day, Vallisaari is an excellent choice for a day trip.
