Day 1: Senate Square, Market Square and the Design District
Senate Square and the free Cathedral, then Market Square and the Old Market Hall for lohikeitto, then the Esplanadi into the Design District, Marimekko, Iittala, and 100-plus shops through Punavuori.
Day 2: Suomenlinna and the Rock Church
The HSL ferry from Market Square (an ordinary AB single ticket, not a paid tour) covers the roughly 15-minute crossing. Roam the free fortress island , add the Suomenlinna Museum (about EUR 10) if you want the history, then ferry back for Temppeliaukio Church , EUR 8, carved into granite bedrock.
Day 3: Sauna, One Museum and Oodi
A Löyly sauna session (roughly EUR 19-29), then either Ateneum or Kiasma (about EUR 23, EUR 21 online), then Oodi library , free and worth an hour on its own.
Day 4: Kallio, Kotiharjun Sauna and HAM
Morning
Kallio sits a short metro or tram ride northeast of the center, a grittier, more local district than the polished core, with cheaper bars and a genuine street-art scene. Kotiharjun Sauna, Helsinki’s last public wood-heated sauna, has run here since 1928; entry is about EUR 23 for the May-September season.
Afternoon
Walk or tram to HAM, the Helsinki Art Museum at Tennispalatsi, about EUR 20 adult, free on the last Friday of the month and during Helsinki Day (12 June) opening hours.
Is Kotiharjun Better Than Löyly?
For an honest slice of everyday Finnish sauna culture, yes. Kotiharjun is cheaper, more atmospheric, and the last public wood-burning sauna still running in the city; Löyly wins on comfort and easy sea-swim access for a first-timer. Doing both across four days, as this itinerary does, shows you the full range rather than picking a side.
Evening
Dinner in Kallio, the neighborhood’s bar and restaurant scene runs later and cheaper than the center. Fly out the next morning, or keep going with the 5-day itinerary , which adds the Allas Sea Pool and Katajanokka.
Buy Kallio-bound transit through the HSL app , the same AB single ticket that got you to Suomenlinna covers this too. Confirm current sauna hours directly with each venue before you go, both occasionally shift their public sessions around private bookings.
