Suomenlinna Sea Fortress
An 18th-century island fortress spread over six islands, a UNESCO World Heritage Site since 1991, with museums, tunnels, cafes and sea views. Residents live in the fortress year-round.
Tip: The HSL ferry uses ordinary public-transport tickets, so a day ticket covers the crossing. · Bring a picnic and layers; sea wind is cooler than in the city. · Museums sell separate tickets, so choose one or two rather than all. · Wear sturdy shoes for cobbles, gravel and slopes. · Travel in the late afternoon in summer for quieter paths and softer light. · Check the last return ferry time before exploring the far islands.

Tips for visiting attractions
Make the most of your sightseeing time.

Most Helsinki museums close on Mondays, so schedule markets, Suomenlinna, and saunas for Monday
Check seasonal closures: Seurasaari (mid-May to mid-September), Hvitträsk and Ainola (May to September), Linnanmäki (spring to early autumn)
Cash is rarely needed; cards and phone payments are accepted almost everywhere, including ferries and small cafes

Leave time for the last ferry from Suomenlinna and check evening sailings in autumn and winter
Frequently asked questions
When is the best season to visit attractions in Helsinki?
June to August offers the longest days and all seasonal sights open; late May and September are quieter. Winter suits saunas and Nuuksio snow trails, but many island and house museums are closed.
How much does it cost to visit Suomenlinna?
Walking the island is free. The ferry uses an HSL AB ticket at €3.30 by app or card or €3.50 contactless (about $3.80-4.10 USD), and each museum charges its own fee of roughly €5-11 (about $6-13 USD).
Is Nuuksio National Park reachable without a car?
Yes. Take a commuter train to Espoo Centre, then bus 245 (245A in summer) to the Haltia stop. An ABC ticket is needed and the bus journey takes about 25 minutes.
Can I visit Porvoo as a day trip from Helsinki?
Yes. Buses from Kamppi Bus Station take about one hour, and the old town can be seen in three to four hours. Book tickets at matkahuolto.fi.
