Twenty minutes. That’s how long it takes to get from central Helsinki to an island that was closed for over 200 years. The ferry leaves from Market Square, and the city disappears behind you faster than you’d expect. On the other end: an island where the forest has grown through the bunkers and the wine bar terrace looks out over the Baltic in every direction. Here’s everything you need to know about the crossing.
Route and Schedule
The JT-Lines ferry departs from Kauppatori (Market Square) in central Helsinki and arrives at Vallisaari’s Luotsipihka pier in 20 minutes. The ferry runs from May through September, roughly every 30 minutes in summer. Some routes continue to Suomenlinna — meaning you can combine both islands in a single day without returning to the mainland.
First ferry around 10:00. Last ferry back approximately 20:00–21:00. On event nights there may be later crossings — check the Vallisaari events calendar and that day’s schedule before you go.
The last ferry is non-negotiable. Write down the time. Set an alarm. Missing it means a water taxi costing 50–150 euros. That’s the most expensive ferry you’ll ever buy.
Tickets
Tickets are available from JT-Lines’ online shop or from the ticket counter at the Market Square pier. Check current prices on JT-Lines’ website. Children under 7 travel free.
Buy in advance. On weekends — especially sunny days — the queue at Market Square builds and ferries fill. With an online ticket, you walk straight on board.
The Crossing
Arrive at the pier 10 minutes before departure. Go up to the deck — 20 minutes of sea views, Helsinki shrinking behind you, Vallisaari growing ahead. The ferries are accessible. There are toilets on board.
On arrival, it’s 100 metres from the pier to Cafe IISI’s terrace (accessible route), and a ten-minute walk to Torpedolahti harbour, where IISI Bistro and the famous salmon soup are waiting. The island is entirely pedestrian — no cars, no bikes, no rush.
Suomenlinna Combination
Some JT-Lines services run directly between Vallisaari and Suomenlinna — meaning you can start the morning at the UNESCO fortress and continue in the afternoon to Vallisaari without returning to the mainland. Check the day’s route map for which departures connect the islands.

By Private Boat
Vallisaari can be reached by private boat via Torpedolahti harbour. No reservation, no fee — but space is limited on busy summer weekends.
