Explore Suomenlinna’s sea fortresses with an engaging self-guided audio tour. Discover Helsinki’s history at your own pace for an authentic experience.

If you’re planning a trip to Helsinki, the Suomenlinna sea fortress is a must-see. This UNESCO World Heritage Site spans six small islands and offers a fascinating glimpse into Finland’s military past. The self-guided audio tour by VoiceMap provides a flexible way to explore, allowing you to stroll at your own pace while soaking up stories about one of the world’s largest sea fortresses. Priced at just under $12, this tour packs in history, culture, and some surprising Finnish facts, making it perfect for history buffs and curious travelers alike.
What we particularly like about this experience is the combination of detailed narration and the freedom to explore. The tour is designed to be accessible anytime, anywhere, with offline maps and audio, which means you’re not tied to a schedule or a crowded group. However, one thing to consider is that this isn’t a guided group tour—so if you prefer a live guide explaining every nuance, you might find this format a little less engaging. Still, for those who enjoy independence, this is a solid way to uncover Suomenlinna’s secrets. This tour suits travelers interested in history, architecture, or simply those wanting an enriching, leisurely adventure on Helsinki’s scenic islands.

Suomenlinna isn’t just a fortress; it’s an entwined part of Helsinki’s scenery and history. Sprawling across six small islands, it looks as much like a living museum as a strategic military site. The tour begins at the main pier, providing directions that ensure you start on the right foot. From there, the narration kicks in with captivating stories about the fortress’s origins and its evolution over centuries.
What makes this tour appealing is the ability to explore at your own pace. You can linger at each stop or move swiftly, depending on your interests and energy levels. The tour duration is roughly 2 to 3 hours, which makes it ideal for a half-day outing—perfect for combining with Helsinki city sightseeing.
One of the first stops takes you to the Jetty Barracks, which once housed up to 250 soldiers during peacetime. The narrator explains how the barracks were designed for efficiency and defense, giving you a tangible sense of military life. Visitors have noted the historical detail here helps paint a vivid picture of life on the island, even if you’re not a military history buff.
Next, the tour guides you to the Suomenlinna Church, originally an Orthodox garrison church. Now an Evangelical-Lutheran church, it’s a striking example of how buildings evolve over time. The narration adds context about its dual religious history, making it more than just a photo spot.
Moving to the Great Courtyard, you’ll find the grave of Augustin Ehrensvärd, the fortress’s founder. The story of Ehrensvärd’s mission to strengthen Finland’s defenses during the 18th century is told with enthusiasm. Some reviews share that the narrator’s storytelling makes history come alive, especially when they relate Ehrensvärd’s strategic sense to today’s military engineering.
Further around the island, the tour covers the Mortuis Memorial Stone, a poignant marker, and the 1918 Prisoner-of-War Camp Memorial, which commemorates the nearly 8,000 prisoners held during WWI. The Military Museum of Mannerheim is also mentioned, giving a rounded view of Finland’s military past. One reviewer appreciated hearing about the Vesikko submarine, launched from Turku during WWII, which adds a naval dimension to the story.
The tour recounts a walk through King Adolf Frederick’s first steps through King’s Gate in 1752, and passes by Gyllenborg Bastion and Hårleman Bastion, key parts of the fortress’s outer defenses. These structures are well-preserved and tell of Finland’s defensive strategies.
This tour is delivered via a smartphone app, so you’ll need to bring your own device and headphones. It’s designed to be easy to follow, with clear directions and offline access—meaning no worries about Wi-Fi dead zones on the islands. Price-wise, at $11.99, it’s a cost-effective way to learn about Suomenlinna without the expense of guided tours or entrance fees.
While the tour doesn’t include access to attractions like museums or the submarine Vesikko itself, it provides plenty of background info that enhances any physical visit. It’s a self-guided experience, so you determine your pace, whether you want a quick overview or a detailed exploration.

Compared to typical guided tours, the self-guided format offers more freedom. The narration acts as your personal guide, providing detailed stories and facts that would otherwise require a guide’s presence. Guests have found the narration to be generally informative, although some mention that it could include more explanations of military terms for those unfamiliar with 19th-century fortifications. The tour is also accessible at any time of day, fitting well into various travel schedules.
One reviewer mentioned that an improvement would be more contextual military explanations—a valid point if you’re not familiar with military architecture. Plus, since this is a virtual tour, it lacks the personal touch of a live guide, which might make some parts feel a little static. However, for many, the ability to explore independently outweighs these minor drawbacks.
This experience is especially well-suited for history enthusiasts who enjoy self-paced exploration. It’s also ideal for those looking for a budget-friendly yet immersive way to understand Suomenlinna’s significance. Travelers who appreciate audio guides and flexibility will find it a great companion, especially if you want to avoid large group tours or rigid schedules.
If you’re visiting Helsinki and want a deep dive into the island’s military architecture and stories, this tour provides a solid foundation.

It offers authentic insights into Finland’s military history, paired with the flexibility of a self-guided experience. Whether you’re a history buff, a curious traveler, or someone who simply wants to learn more about Helsinki’s iconic fortress, this tour delivers a good balance of information and independence.
The narration is engaging, and the ability to listen offline makes it especially convenient for island exploring, where connectivity may be spotty. While it might lack a live guide’s charismatic storytelling, the depth of content and ease of use make it a worthwhile choice for most visitors.
This tour is especially recommended for travelers who value flexibility, affordability, and a touch of Finnish humor and culture. If you’re looking for a meaningful way to uncover the stories behind Suomenlinna’s impressive defenses—and enjoy doing so on your own terms—this self-guided audio tour is a smart, enjoyable way to do just that.
