Why FRS Finland waterbus is the best way to visit Suomenlinna this summer
For visitors looking for convenience, comfort, and flexibility, the FRS Finland waterbus is the ideal way to explore both Suomenlinna and nearby Lonna Island.
One of the biggest advantages of the FRS Finland waterbus is its arrival location. The waterbus arrives at one of the most convenient visitor locations on Suomenlinna, placing many of the island's main attractions within easy walking distance. This allows visitors to make the most of their time on the island from the very beginning of their visit. From here, museums, historic fortifications, cafés, restaurants, and scenic seaside views are all easily accessible.
Suomenlinna itself is one of Finland's most remarkable historic sites. Built in the mid-18th century as a sea fortress, it spans several islands and is today recognized as a UNESCO World Heritage Site. Its combination of military history, beautiful nature, and vibrant local community attracts visitors from around the world throughout the summer season.
The FRS Finland waterbus also offers outstanding flexibility. Your roundtrip ticket allows you to return at any departure time on the same day, giving you complete freedom to explore at your own pace. When it's time to head back to Helsinki, you can choose to depart from either Artillery Bay or the famous King's Gate, one of Suomenlinna's most iconic landmarks. This means you can comfortably explore the island from one end to the other without having to retrace your steps.
During the busy summer months, the FRS Finland waterbus can also help you avoid possible queues at Market Square. Instead, you can enjoy a relaxed journey across the archipelago while taking advantage of the onboard amenities. Grab a refreshment from the café, find a comfortable seat, or head to the spacious sundeck and enjoy the beautiful sea views on your way to the islands.
Your ticket also includes the opportunity to visit Lonna Island, a charming destination located between Helsinki and Suomenlinna. Despite its small size, Lonna has a fascinating history. The island was once used by the military for storing naval mines and later housed a demagnetizing facility, where ships were treated to reduce their magnetic signature and better protect them from naval mines. Today, Lonna has been transformed into a popular summer destination known for its waterfront atmosphere, restaurant, terrace, and public seaside sauna, where visitors can enjoy a uniquely Finnish experience in the heart of the archipelago.
