The Suomenlinna ferry will operate a more frequent service on weekdays from Monday 8 June. The ferry will operate the weekend timetable also on weekdays, i.e. the ferry from the Market Square to Suomenlinna will operate the same timetable every day of the week.
The new timetables will be available in the Journey Planner from 1 June. New timetables in PD format: 
Market Square-Suomenlinna from 8 June
The change is made to accommodate the increasing demand. Passenger numbers on the ferry continue to be limited to ensure physical distancing on the ferry.
If you are traveling to Suomenlinna, remember the following safety advice: only travel if you are healhty; distance yourself from other passengers; cough into a tissue or your sleeve; wash or sanitize your hands regularly; and buy your tickets using the mobile app. For more information about safe travel and the effects of coronavirus on public transport, see our coronavirus information page at hsl.fi/en/corona
