Things to do
Helsinki occupies a granite peninsula on the Gulf of Finland, where wide avenues give way to rocky shorelines. The centre is walkable, trams link the harbour with Kallio, and ferries from Market Square cross to the island fortress.
Suomenlinna
The ferry from Market Square reaches the Suomenlinna fortress in about fifteen minutes. Walk the ramparts to the dry docks and bastions, then take a late ferry back when the wind drops.
Market Square and Esplanadi
Begin at Market Square, where stalls sell berries, fish and crafts in summer. The presidential palace stands by the harbour, and the Esplanadi park leads past the Design Museum to coffee on Kasarimikatu.
Töölö and the rock church
Temppeliaukio Church is cut into solid granite, and the room keeps an unusual quiet. From there walk to the Sibelius Monument and circle Töölönlahti bay, where the central Oodi library stands.
Where to stay
Kruununhaka
Kruununhaka sits beside Senate Square, the cathedral and the harbour, which makes it practical for a short stay. The buildings are historic and the streets quiet, though few cafés and bars stay open late.
Kallio
Kallio draws people for cheaper rooms, bars and a market where locals eat lunch. Trams reach the centre in about fifteen minutes; the district is lively, and weekends stay noisy until morning.
Punavuori
Punavuori and Ullanlinna hold design shops, galleries and coffee rooms in Jugend-style blocks. It is a good base for families and anyone who values quiet streets; Uunisaari beach is twenty minutes away on foot.
Getting to and around Helsinki
Helsinki-Vantaa airport connects to the central railway station by the I and P commuter trains on the ring line, a journey of about half an hour. Trams are the main way around the centre and reach Kallio and Töölö. One ticket covers trams, buses, trains and ferries within the zones, and the Suomenlinna ferry belongs to the city network.
Three days in Helsinki
Senate Square and the design district
Start at Senate Square and the white cathedral, look into Uspenski Cathedral and cross to Market Square. Walk the Esplanadi to the Design Museum in the afternoon and spend the evening in Punavuori.
Suomenlinna fortress
Take a morning ferry to Suomenlinna and follow the walls, docks and bastions around the island. Back in the city, climb to Kallio for dinner and a view over the roofs.
Töölö and Oodi library
Visit Temppeliaukio Church, then walk to the Sibelius Monument. Circle Töölönlahti bay and step into the Oodi library, which stays open late and has quiet seats upstairs, before finishing at Kiasma.
