Explore Helsinki's archipelago with a flexible hop-on hop-off boat cruise to Suomenlinna and Lonna—affordable, scenic, and perfect for a relaxed day out.
If you’re planning a trip to Helsinki and looking for an easy, budget-friendly way to soak up the city’s maritime charm, the Suomenlinna and Lonna hop-on hop-off cruise might just be your best bet. Priced at only $10 per person, this experience offers a relaxing way to explore Helsinki’s famed archipelago from the water, with the flexibility to choose your stops and return times.
What we love about this cruise is how it combines spectacular views with the freedom to customize your day. The chance to hop off at Suomenlinna, a UNESCO World Heritage Site, or visit the tiny Lonna island with its well-regarded restaurants, makes it a practical yet scenic outing. However, keep in mind that the cruise primarily focuses on transportation and sightseeing, so if you’re after a guided tour or in-depth history, you’ll need to plan additional activities.
This experience is perfect for travelers who appreciate value for money, want a relaxed pace, and are keen to experience Helsinki’s stunning maritime scenery without breaking the bank. It suits both solo explorers and families, especially those who enjoy spontaneous island visits.
When you think about Helsinki’s maritime side, images of calm waters, islands dotted with colorful wooden houses, and historic forts probably come to mind. This cruise offers an ideal way to see all of that from a relaxed vantage point. Starting at the bustling Market Square, you’ll board a boat operated by FRS Finland, whose friendly crew and captain provide a smooth and informative ride.
The journey out of Helsinki’s harbor is a treat in itself. We loved the way the boat glided through the water, offering unobstructed views of the city skyline and the surrounding islands. The calm seas and open decks make for a perfect photo opportunity, whether you’re snapping pictures of the Helsinki Cathedral or capturing the distant silhouette of Suomenlinna’s fortress walls.

Most travelers choose to hop off at Suomenlinna, and with good reason. This massive sea fortress is one of Helsinki’s top attractions—and for good reason. As one reviewer noted, Suomenlinna is “large enough to spend hours walking and exploring,” with historic walls, tunnels, and museums to discover. The island’s well-preserved architecture creates an authentic maritime ambiance.
If you’re into history, you’ll love wandering through the fortress, imagining what life was like when it served as a defensive stronghold. It’s also a lively place with cafes, shops, and parks. The flexible schedule means you can stay as long as you like—some visitors report arriving early and staying until late afternoon, making the most of their visit.
Lonna often gets overshadowed by Suomenlinna but offers its own unique appeal. It’s a tiny island with a couple of notable restaurants, making it ideal for a quick stop for coffee, lunch, or a snack. One reviewer mentioned that Lonna “isn’t really interesting,” but this depends on what you’re after. If you’re keen on a peaceful spot with good food and views, Lonna fits the bill.
You’ll find that the boat’s schedule allows you to hop off here, enjoy a meal, and be back on the boat at your convenience. It’s a great way to break up the day and experience some local culinary flavors.
The cruise is primarily a transportation service, but it doubles as a sightseeing platform. The boats are well-maintained, and the crew is friendly and informative. The average departure every 30 minutes makes it easy to plan your day without feeling rushed or waiting too long.
One of the best aspects is the “return at your leisure” policy—meaning you can get off at Suomenlinna or Lonna and catch the next boat back when you’re ready. You’ll want to check the schedule, especially if you plan to stay late or hop between islands multiple times.
The price point—only $10—is remarkably reasonable, especially considering the views and the convenience. Keep in mind that food and drinks are not included, so bring snacks or plan to dine on the islands. The boat trip itself doesn’t include guided commentary, but the crew is happy to answer questions and point out interesting sights.
From reviews, it’s clear that many travelers find this cruise to be excellent value. One reviewer called it a “very good idea for a whole day of island visits,” praising the ability to spend multiple hours on Suomenlinna. They also noted that the day was “well-filled,” thanks to the flexible schedule.
Another interesting insight is that, despite the straightforward nature of the cruise, the stunning views make it memorable. The sight of Helsinki’s skyline against the backdrop of the archipelago is something you won’t want to miss.
A downside for some is Lonna’s limited attractions, but if your main goal is Suomenlinna, this isn’t a big concern. The cruise’s primary appeal is the scenic, no-hassle transportation that allows you to explore at your own pace.

The Helsinki Suomenlinna and Lonna hop-on hop-off cruise provides an affordable, flexible, and scenic way to experience the city’s beautiful islands. It’s perfect if you’re after breathtaking views, spontaneous island visits, and a relaxed pace—all on a budget. Whether you’re solo, a couple, or with family, the ease of hopping on and off makes it an excellent addition to your Helsinki itinerary.
While the trip isn’t a guided tour and food isn’t included, the value for money and the stunning scenery more than compensate. It’s especially suited for travelers who love outdoor adventures, photo opportunities, and spontaneous exploration. If you’re looking for a simple, enjoyable way to see Helsinki from the water without overcomplicating things, this cruise is a solid choice.
