The guide

Helsinki is best explored on foot and by tram. The neoclassical heart centres on Senate Square and its white cathedral, while the Design District, between Punavuori and Kaartinkaupunki, lines up designer boutiques, galleries and cafés. To the north, Kallio is the hip, down-to-earth district: vintage shops, bars and street food just five tram minutes from the centre. Don't miss Oodi, the central library nicknamed « the city's living room », with its maker space and terrace facing Parliament. The sea is everywhere: take the ferry to the UNESCO-listed Suomenlinna sea fortress, or unwind at Löyly sauna on the waterfront. In summer the northern light barely fades; in winter the city retreats into its cafés.

During the Cold War, Helsinki often stood in for Moscow on screen. In « Gorky Park » (1983), the tower of the Finnish National Museum on Mannerheimintie was topped with a giant red star raised by crane to pose as the Kremlin, while Kaisaniemi Park, near the central railway station, played the famous Gorky Park itself.

The Havis Amanda statue, unveiled in 1908 on Market Square, caused a scandal: MP Lucina Hagman, one of the world's first female parliamentarians, called it indecent and demanded its removal. Today, every 30 April, students crown the bronze mermaid with a white cap to kick off the Vappu May Day festivities.

For a genuine Finnish break, head to Kotiharjun Sauna in Kallio, the city's last wood-fired public sauna, running since 1928 and refreshingly no-frills. Book your Suomenlinna ferry ticket and check the timetable online with a data eSIM, as public wifi is scarce out on the ramparts.

Must-see

Suomenlinna Sea Fortress
18th-century UNESCO-listed maritime citadel spread across six islands. A 15-minute ferry from Market Square; allow 3 to 5 hours to follow the Blue Route past bastions and tunnels.
Oodi Library
A vessel of wood and glass facing Parliament, nicknamed Helsinkians' living room. A light-filled upper floor for reading, plus 3D printers and sewing machines free to use on the ground floor.
Löyly Sauna
A striking public sauna on the Hernesaari waterfront with three wood-fired saunas and year-round sea swimming. Its restaurant serves creamy salmon soup and Finnish meatballs.
Kotiharjun Sauna
A Kallio institution since 1928 and Helsinki's last wood-fired public sauna. An authentic, local atmosphere where bathers cool off sitting on the pavement between steam sessions.

Good to know

The best season runs June to August, for long days and terraces; winter is dark but magical. Everything is walkable or covered by the HSL network (trams, buses, metro, ferries): a single ticket covers it all, Suomenlinna ferry included. Tip: buy the HSL day ticket via the app rather than single fares. On connectivity, 4G/5G is excellent and free wifi is everywhere in cafés, museums and Oodi library, but it thins out on the islands and Suomenlinna's ramparts: a data eSIM keeps maps and ferry times running without a gap.
