Flights to Helsinki — What to Expect
Helsinki is served by Helsinki-Vantaa Airport (HEL), Finland's main international hub located about 19km north of the city centre. It's a well-run, compact airport — you won't spend 45 minutes hiking between terminals. The national carrier Finnair operates the most extensive network into HEL, with direct routes from London Heathrow, Amsterdam, Frankfurt, Paris CDG, Stockholm, and most major European capitals. Ryanair connects Helsinki to a growing list of European cities at budget fares, though check that you're flying into HEL and not Tampere. SAS, Lufthansa, KLM, and easyJet also cover the route regularly. Flights to Helsinki from London typically run 2h 45m to 3h, from Amsterdam around 2h 30m, and from Frankfurt about 2h 20m.
Flight prices vary significantly by season. Cheap flights to Helsinki are easiest to find in the shoulder months — May and September — when demand drops but the city is still very much worth visiting. Summer fares, especially July, spike hard because this is peak Scandinavian travel season. If you're hunting Helsinki flight deals, book at least 6–8 weeks out for summer travel, and you'll often find better fares midweek. Flights from London to Helsinki in peak summer can range from €80 return on Ryanair to €300+ on Finnair. Budget around €120–€200 return from Western Europe if you're booking a month or two ahead.
Best Time to Visit Helsinki
June through August is the sweet spot. Temperatures hover between 16–22°C, daylight stretches up to 19 hours in late June, and the city genuinely comes alive — outdoor markets, island hopping, terrace bars packed until midnight in full sunlight. Midsummer (late June) is a big deal in Finland; just know that the city itself quiets down as locals head to their summer cottages, so some smaller shops and restaurants close. July is the warmest month on average and the busiest for tourism. August is excellent — slightly fewer tourists, still warm, and the Baltic light turns golden.
May and September are underrated. May averages around 10°C but can surprise you with warm spells, and the city is fresh and uncrowded. September cools to 6–12°C but foliage is beautiful and cultural events ramp back up after the summer lull. December and January are cold (regularly below -4°C) with short days — sometimes only 6 hours of light — but Helsinki handles winter well. Christmas markets at Senate Square, ice skating, and the sauna culture make it genuinely atmospheric rather than just cold. March and April are the weakest months — lingering snow, grey skies, and not yet warm enough for outdoor activity. Skip unless you have a specific reason to go.
Getting Around Helsinki
From Helsinki-Vantaa Airport, the Ring Rail Line (I or P train) is your best option — it runs every 10 minutes, takes about 30 minutes to the city centre (Central Railway Station), and costs around €4.10 with the regional HSL ticket. Taxis are plentiful but expensive; expect €35–€50 to the centre. Ride-hailing apps like Uber and local operator Bolt are cheaper alternatives to street taxis. Once in the city, Helsinki's HSL public transport network is excellent — trams, metro, buses, and ferries all run on the same ticket system. A single journey costs €2.95 if bought via the HSL app (more expensive from the driver). The city is also extremely bikeable; city bikes (Fillarit) are available April through October at docking stations everywhere and cost €5 for a week pass. The centre is walkable enough that for many days you won't need transport at all.
Where to Stay in Helsinki
The city centre (Keskusta) around Esplanadi and the Market Square is the most convenient base — you're walking distance from the harbour, Senate Square, and the main shopping streets. Expect to pay €120–€220 per night for a decent mid-range hotel here. Kallio, northeast of the centre, is the neighbourhood locals actually live in — independent cafés, bars, a younger crowd, and noticeably cheaper accommodation, often €70–€120 for a solid guesthouse or budget hotel. It's a 15-minute tram ride to the centre. Punavuori (aka the Design District) is a great middle ground — stylish, walkable, boutique hotel territory at €100–€180 a night. For premium stays, the Hotel Kämp on Esplanadi is the classic Helsinki luxury choice; Scandic hotels offer reliable mid-range options across multiple city locations.
Top Things to Do in Helsinki
- Explore the Market Square (Kauppatori): The waterfront market near the South Harbour is where Helsinki feels most itself — fresh salmon soup, reindeer meat pies, local berries in summer, and ferries to the islands departing from the same quay.
- Visit Suomenlinna Sea Fortress: A UNESCO World Heritage island fortress a 15-minute ferry ride from the Market Square. Spend a half-day exploring the ramparts, museums, and coastal paths. The ferry runs on the standard HSL ticket.
- Go to a Public Sauna: Sauna is not a tourist gimmick here — it's infrastructure. Löyly in Hernesaari and Allas Sea Pool near the harbour are the most accessible for visitors; both have outdoor swimming in the Baltic.
- Temppeliaukio Church (Rock Church): Carved directly into solid bedrock in the Töölö neighbourhood — the acoustics and architecture are worth the €5 entry, even if you're not a church person.
- Design District and Design Museum: Helsinki takes design seriously in a way that doesn't feel performative. The Design Museum covers Finnish industrial and product design history; the surrounding streets are full of independent studios and shops worth browsing.
- Day trip to Porvoo: Finland's second oldest city, 50km east by bus or boat — cobblestone streets, ochre wooden riverside houses, and good independent cafés. Easy half-day from Helsinki.
Practical Travel Tips
Visas: EU citizens need only a valid ID card. UK citizens post-Brexit can enter visa-free for up to 90 days with a valid passport — Finland is part of the Schengen Area. US, Canadian, and Australian passport holders are also visa-free for short stays under 90 days. Currency: Finland uses the Euro (€). Card payment is accepted almost universally — you can go days without needing cash. Tipping: Not obligatory and never expected. Rounding up or leaving a few euros at a restaurant is appreciated but nobody will be offended if you don't. Safety: Helsinki is one of the safest capitals in Europe. Normal urban awareness applies but there are no areas you need to actively avoid as a tourist. Language: Finnish is the local language but English proficiency is effectively universal — you will not struggle to communicate anywhere in the city.

January and February typically have the lowest fares — demand is at its lowest and airlines discount heavily. However, these are also the coldest and darkest months.

Set fare alerts on Google Flights or Skyscanner for Helsinki flight deals and you'll catch drops quickly.
How long is the flight to Helsinki from London?
