Helsinki Travel Guide: Things to Do & Best Time to Visit

Top things to do in Helsinki

Helsinki’s centre is compact and flat, so most sights can be reached on foot or by tram, with ferries linking the city to its many islands.

• Suomenlinna — A UNESCO-listed sea fortress spread across several islands, reached by a short ferry ride from Market Square and perfect for walks and picnics.
• Senate Square and Helsinki Cathedral — The city’s grand neoclassical heart, dominated by the white, green-domed cathedral at the top of its steps.
• Market Square and Old Market Hall — A harbourside market with food stalls and crafts, next to a historic indoor hall selling Finnish delicacies.
• Uspenski Cathedral — A striking red-brick Orthodox cathedral on a hill overlooking the harbour.
• Temppeliaukio Church — Known as the Rock Church, it is carved directly into solid bedrock and topped with a copper dome.
• Oodi Central Library — An award-winning public library with a flowing wooden design, a rooftop terrace and spaces open to all.
• Public saunas — Try a traditional Finnish sauna at one of the city’s public saunas, many of which offer a refreshing dip in the sea.

Best time to visit Helsinki

June to August is the peak season, with mild temperatures, outdoor cafés and very long days. Around midsummer the nights stay light, and ferries to the islands run frequently. On the midsummer weekend in late June, many locals leave for their summer cottages, so the city feels quieter.

Spring and early autumn are cooler but pleasant, with fewer visitors. September brings crisp air and autumn colours in the parks, while late autumn tends to be grey and dark.

Winter is cold, with short days and frequent snow, and parts of the sea can freeze. December is atmospheric, with a Christmas market on Senate Square and festive lights along the Esplanade, and a warm sauna feels especially good at this time of year.

Getting from the airport

Helsinki Airport is located in the neighbouring city of Vantaa, around 17 kilometres north of Helsinki’s centre, and is well linked by rail and road.

• Train — Commuter trains run frequently from the airport station, reached from the terminal, to Helsinki Central Station in around 30 minutes.
• Bus — Regional and express buses connect the airport with the city centre in around 30 to 45 minutes, depending on traffic and stops.
• Taxi — Taxis are available outside the terminal, and the drive to the centre usually takes 25 to 30 minutes.

Train and regional bus tickets can be bought from machines at the airport or through the official public transport app; make sure your ticket covers the airport zone.

Where to stay

Helsinki is small and easy to navigate, and trams connect most central districts, so you can choose based on atmosphere.

• City centre and Esplanade — Ideal for first-time visitors, close to Senate Square, Market Square, the ferry piers and the main shopping streets.
• Kamppi — A busy central area near the main bus terminal and metro, convenient for transport and shopping.
• Design District — Covering Punavuori and nearby streets, it is packed with design shops, galleries and restaurants, suiting style-conscious travellers.
• Kallio — A lively, bohemian neighbourhood with bars, cafés and public saunas, popular with younger travellers.
• Töölö — A calm residential district near parks, the Rock Church and the seaside, good for a quieter stay.

Travel tips

• Getting around — Trams, buses, the metro, commuter trains and the Suomenlinna ferry share one ticketing system. Buy tickets before boarding via the official app or ticket machines.
• Payment — Cards and contactless payments are accepted almost everywhere, even for small purchases, so you will rarely need cash.
• Tipping — Service is included in prices and tipping is not expected, though leaving a little extra for good service is welcome.
• Sauna etiquette — Shower before entering. Single-sex saunas are often used without swimwear, while mixed public saunas usually require it.
• Local customs — Finns value personal space and quiet, especially on public transport. Tap water is excellent and safe to drink.
• Entry requirements — Finland is part of the Schengen area. Visa and entry rules depend on your nationality, so check official sources before you travel.
