Skip the Walking Tour But Go to the Fortress

3.00The FRS Finland ferry was really nice. Way less crowded than the main ferry. Operated right on time. The guided walking tour wasn’t worth the time or money. It took an hour and only hit three spots on the island. The tour can also be booked from the gift shop on the island if you feel like it. If you do this trip, the FRS Finland boat picks people up on the island twice an hour at two different locations. My recommendation: book your ferry directly with FRS Finland and skip the walking tour. But definitely go to the site…I spent 6 hours in calling all over the island. Good restaurants there too.

4.00Great outing. But very confusing in terms of logistics. Neither the FRS ferry operators or the museum tour guides recognized the e-ticket that was provided. Definitely recommend going out to the island. Lots to see and do.

5.00Attended the guided Suomenlinna tour on the 12 Sep 25. Had an extremely pleasant time walking around the sea fort learning the history and modern day usage of the island. My tour guide Milla did a fantastic job, was extremely knowledgeable, approachable and her English was very clear and understandable. Thanks for a great day out.

3.00nice guided tour, but quite short (55 minutes). The guide very quickly showed the facts and the entire location. All right in terms of content, but (me) too short for the price.
