Turku is Finland’s oldest city and was its capital until 1812. It stands on both banks of the Aura river, a few kilometres from the sea, where riverside cafés, restaurant boats and the little Föri ferry set the pace of life. At the river mouth rises Turku Castle, the largest surviving medieval building in Finland, and the city has fine museums of history, art and seafaring. Beyond the harbour lies the Archipelago Sea, with tens of thousands of islands linked by bridges and small ferries on the Archipelago Trail, and the wooden seaside town of Naantali, home of Moomin World in summer. Overnight ferries sail from Turku to Stockholm via the Åland Islands. Come in summer for the river, islands and Ruisrock festival, or in December for the Christmas City and the Declaration of Christmas Peace. Give it two days for the city and two or three more for the archipelago.

Turku, area by area
According to Statistics Finland, the city of Turku had 212,324 inhabitants in August 2026, making it Finland’s sixth-largest city. A great fire in 1827 destroyed most of the old wooden town, so the centre is largely 19th-century, laid out in a grid on both sides of the river. Turku is bilingual, and you will see its Swedish name, Åbo, on signs.
The city centre and the Market Square
On the west bank, the Market Square (Kauppatori) and the Market Hall, open since 1896, with food stalls and cafés, are surrounded by shopping streets and the Orthodox church. Best for: shopping, food and hotels.
The Aura riverside
The tree-lined banks are the heart of Turku: walk from the cathedral to the castle past restaurant boats, bridges, the Aboa Vetus & Ars Nova museum and the Turku City Theatre. Best for: evening strolls and summer terraces.
The Cathedral quarter and Old Great Square
On the east bank, the cathedral, the Old Great Square (Vanha Suurtori) with the Brinkkala mansion, where Christmas Peace is declared, and the university buildings. Best for: history and Christmas traditions.
Linnanniemi and the harbour
Near the river mouth, Turku Castle, Forum Marinum and the ferry terminals for Stockholm and Åland. Best for: the castle, ships and ferry departures.
Top things to see in Turku
Prices and hours below were checked on the official sites in October 2026. They change by season and around holidays, so check before you go.
Turku Castle
Founded around 1280 as a Swedish fortress at the mouth of the Aura, Turku Castle grew into a Renaissance court under Duke John and Catherine Jagiellon in the 16th century. Today it is a museum: walk through the stone halls, vaults and chapels of the medieval keep, and the Renaissance rooms and historical exhibitions of the bailey. Guided tours bring the history to life, and in summer there are tours of the courtyard.
Tickets and hours. As of October 2026, admission costs €18 for adults, €9 concessions (students, pensioners, the unemployed and conscripts), €8 for children aged 7–15 and €44 for a family (one or two adults and two to four children). From 31 August to 31 December 2026, the castle is open Tuesday to Sunday 10:00–17:00 and closed on Mondays; it closes on 6 December and 24–25 December and opens 10:00–15:00 on 23 December. Last entry is 30 minutes before closing. Entry is free on certain Friday afternoons, 14:00–17:00: 30 October and 27 November 2026. The Museum Card gives free entry.
Turku Cathedral (closed for renovation)
Consecrated in 1300, Turku Cathedral is the mother church of the Evangelical Lutheran Church of Finland and the country’s national shrine, and its brick tower is a landmark of the riverside. As of October 2026, the cathedral is closed for a major renovation from 9 February 2026 until Advent 2028 (planned to 2 December 2028), to renew its building services and improve accessibility. You can still admire it from outside, but plan your visit around the closure.
The Aura river and the Föri ferry
Turku life revolves around the river. In summer, restaurant and bar boats moor along the banks, and locals picnic on the grass. The Föri, a little city ferry that has crossed the Aura near the castle end since 1904, is free and runs all year, a one-minute crossing that is a Turku institution. Walk or cycle the whole riverside from the cathedral to the harbour, about 3 km.
Aboa Vetus & Ars Nova, Forum Marinum and Luostarinmäki
Aboa Vetus & Ars Nova, on the riverbank, combines the excavated streets and cellars of medieval Turku underground with contemporary art upstairs. Forum Marinum, near the castle, is a maritime museum with historic ships moored outside, including the sailing ship Suomen Joutsen. Luostarinmäki Handicrafts Museum is the only part of old wooden Turku to survive the 1827 fire, with craftspeople at work in its old houses in summer. The Turku Art Museum, in a granite castle-like building on a hill, has a fine collection of Finnish art. Check each museum’s own website for prices and seasonal hours.
Ruissalo island
Just west of the centre, the island of Ruissalo is a green escape of oak forest, nature trails, beaches, a botanical garden, old wooden villas and a spa hotel. In summer a boat runs from the city, and buses run all year. Each July it hosts Ruisrock, Finland’s oldest rock festival, on 9–11 July 2027.

The archipelago, Naantali and Moomin World
The Archipelago Trail
The Archipelago Sea off Turku is one of the world’s largest archipelagos, with tens of thousands of islands and skerries. The Archipelago Trail is a circular route of roughly 250 km from Turku through Pargas (Parainen), Nagu (Nauvo), Korpo (Korppoo), Houtskär and Iniö, linked by bridges and small car ferries, many of them free. Drive it in two or three days, or cycle it over four or five, staying in island guesthouses and eating smoked fish in harbour cafés. The full loop works best from June to August, when the summer ferries between Iniö and Houtskär run; the inner part to Nagu and Korpo can be done all year. See our cycling and boat trips guides.
Naantali and Moomin World
Naantali, about 16 km west of Turku and 20–30 minutes by Föli bus, is a pretty seaside town with an old wooden quarter, a 15th-century convent church and a lively harbour. Across a footbridge on Kailo island, Moomin World brings Tove Jansson’s Moomin stories to life with the Moomin house, characters to meet and theatre shows. It is open only in summer: in 2026 the season ran from 9 June to 21 August, and one-day tickets started from about €43. As of October 2026, the 2027 dates and prices had not yet been published, so check the park’s website before planning. Naantali is also home to Kultaranta, the Finnish president’s summer residence, whose gardens can be visited on guided tours in summer.

Festivals and seasons in Turku
Christmas City and the Christmas Peace. Turku calls itself Finland’s Christmas City, with markets, lights and events through December.

Arrive early for a good spot.
Summer. Midsummer (25–26 June 2027) empties the city as locals head to their island cottages. Ruisrock fills Ruissalo on 9–11 July 2027, and summer concerts, river events and the archipelago season keep July and August busy. Moomin World and the summer archipelago ferries run from June to August.

- Pargas, Nagu and Korpo: the first islands of the Archipelago Trail, reachable by bus, car or bike, with ferries between them.
- Rauma: about 1 hour 30 minutes north by road, with Old Rauma, a UNESCO-listed wooden town of some 600 houses.
- The Åland Islands: the ferries to Stockholm call at Mariehamn or Långnäs, so you can stop off for cycling and island-hopping.
- Helsinki: about two hours by train, for a long day in the capital.
Getting to Turku and getting around
By train. VR’s trains link Turku with Helsinki in about two hours and with Tampere in under two hours. Most stop at both Turku Central Station and Turku Harbour, next to the ferry terminals.
By ferry. Viking Line and Tallink Silja sail daily between Turku and Stockholm via the Åland Islands, with both day and overnight crossings of about 11 hours, on large cruise ferries with cabins, restaurants and tax-free shops. Finnlines sails from nearby Naantali to Kapellskär in Sweden via Långnäs on Åland.
By air and bus. Turku Airport (TKU), about 8 km north of the centre, has flights to Helsinki and some European cities, and Föli city buses to the centre. Long-distance coaches run from Helsinki and other cities to the bus station.
Getting around. The centre is easy to walk. Föli, the regional transport authority, runs buses in Turku and to Naantali, Kaarina and Raisio on one ticket system; pay by app, card or at ticket machines. Föli city bikes are available in summer, and the Föri ferry is free. See our city sightseeing guide for more ideas.
When to go and how long to stay
Turku has one of the warmest summers in Finland, thanks to its south-western position, and winters that are cold but usually less snowy than inland. The table uses the Finnish Meteorological Institute’s official 1991–2020 normals for Turku airport (temperatures) and Turku Artukainen (rain and snow), as submitted to the World Meteorological Organization.
| Season | Average daily high | Average nightly low | Rain/snow per month | What it’s like |
|---|---|---|---|---|
| Winter (Dec–Feb) | −1 to 1 °C | −7 to −4 °C | 42–73 mm | Short, dark days, snow and slush; Christmas City and the Christmas Peace |
| Spring (Mar–May) | 3 °C rising to 16 °C | −5 to 5 °C | 32–39 mm | The driest season; riverside terraces open in May |
| Summer (Jun–Aug) | 20–23 °C | 9–13 °C | 55–74 mm | Long, light days, archipelago ferries, Moomin World, Ruisrock |
| Autumn (Sep–Nov) | 16 °C falling to 4 °C | 7 °C falling to −1 °C | 59–73 mm | Mild September, then grey and wet; quiet museums and good hotel prices |
Turku gets about 680 mm of rain and snow a year, with at least 1 mm on about 112 days. July is the warmest month, with highs of about 23 °C; February is the coldest, with nights around −7 °C. Most archipelago services, Moomin World and the castle’s longer summer hours run from June to August, so summer is the best time for a combined city and islands trip.

A type C/F travel adapter and a contactless card complete the list.
