Helsinki: Suomenlinna and Lonna Hop-on Hop-off Cruise offers a picturesque way to explore some of the city’s most beloved islands. For just $10, this short yet flexible boat trip from Helsinki’s Market Square takes you to Suomenlinna, a UNESCO-listed fortress island, and Lonna, a tiny island known for its cafes and relaxed vibe. With a 4.6/5 rating from 44 reviews, this experience strikes a solid balance between affordability and authentic enjoyment. It’s ideal for travelers craving a quick maritime escape without the fuss of complicated logistics.
What I particularly like about this cruise is how it combines stunning views of Helsinki’s archipelago with the freedom to customize your day—you can hop off, wander at your own pace, then hop back on when it suits you. Plus, the round-trip option means you can simply relax and enjoy the scenery if you prefer a leisurely cruise. However, keep in mind that the island of Lonna isn’t quite as expansive or eventful as Suomenlinna, so if your main goal is to experience a large, walkable fortress, Suomenlinna is the highlight.
One small consideration is the limited schedule and the need to plan your return timing. While departures are frequent (about every 30 minutes), you’ll want to check the specific timing to ensure you get enough time on each island. Also, food and drinks are not included, so packing a snack or planning to visit the cafes on Lonna might enhance your visit.

Suomenlinna: The Fortress Island of Helsinki

Most travelers’ main reason for taking this cruise is visiting Suomenlinna, a sprawling fortress that’s more than just a historical site. It’s a lively community, with narrow streets, museums, cafes, and military ruins. While it’s possible to stay on the boat for the entire trip, most people find that hopping off here is well worth it.
According to reviews, Suomenlinna is large enough to spend multiple hours walking and exploring. You’ll love the way the island combines history with nature, with views of the sea on all sides and plenty of photo opportunities. One reviewer notes, “Suomenlinna is an island large enough for a full day, and the walkways are quite charming.” Plus, there’s enough to see and do that you won’t feel rushed.
The island’s UNESCO World Heritage status hints at its significance, and it’s a great place to learn about Helsinki’s past. You might find guided tours or simply wander on your own, enjoying the fresh sea air. For those who want to make the most of their time, arriving early and planning your return accordingly helps maximize your visit.
Lonna: A Cozy Island for Relaxation and Refreshments

Lonna is a much smaller island, famous for its casual cafes and relaxed atmosphere. It’s an excellent stop for a quick break, perhaps with a coffee on the deck or at one of the island’s eateries. The reviews suggest that while Lonna isn’t as extensive or historically significant as Suomenlinna, it offers a peaceful respite.
If you’re looking for a scenic spot to unwind or grab a snack, Lonna fits perfectly. The island’s charm lies in its simplicity—small, quiet, and with beautiful views back towards Helsinki. It’s worth noting that some visitors mention that “Lonna isn’t particularly interesting,” but if you enjoy laid-back island atmospheres, it’s a lovely stop.

One of the biggest advantages of this cruise is the ability to choose your return time. You can hop on the boat again when you’re ready—whether that’s after a couple of hours or a full day.

The round-trip fare, included in your ticket, makes this simple. If you prefer, you can stay on the boat for a full scenic cruise, enjoying the tranquility of the archipelago without getting off. This flexibility is perfect for those who value relaxed exploration over strict schedules.
Practical Details: Making the Most of Your Day

The cruise is priced at only $10 per person, which, given the views and island access, makes it an excellent value. Remember, food and drinks are not included, so bringing a water bottle or snack is wise—especially if you plan a longer stay on Suomenlinna.
Departures are roughly every 30 minutes, so planning around the schedule is straightforward. Besides, the boat’s schedule is available online at the provider’s website, ensuring you can check the latest timings and plan accordingly.
