Helsinki Market Square to Lonna

This tiny island, just 150 m long, is part of the Suomenlinna district, located between Helsinki’s Market Square and the Suomenlinna fortress island. JT-Line´s water buses will take you to the Lonna according to the route schedule.

The water bus leaves from the Market Square’s Kolera-allas pier. The island is only 1.5 km from the mainland, so the journey takes just 10 minutes.

Timetables can be found from JT-line´s website or Journey Planner.

You can also arrive to Market Square with city bikes. Stations are few stops away from water bus dock.

Guest dock

Lonna currently doesn’t have a guest dock so unfortunately no landing with private boats.

Accessibility on the island

Island’s terrain is generally easy to get around and distances between buildings are short. All the buildings are accessible.  JT-Line’s water bus crew will be happy to help you board the ship and land.
