Best Things to Do in the Turku Archipelago (2026)

The Archipelago Trail (Saariston Rengastie) is the defining way to experience the Turku Archipelago: a roughly 200-kilometre signed loop that runs south and west of Turku and hops between islands on bridges and small, mostly free, car ferries. It threads through Pargas, Nauvo and Korpo past red wooden cottages, working harbours, island churches, farm shops and swimming spots, and you can drive it in one long day or, far better, spread it over two or three with overnight stops. Cycling the loop is hugely popular and arguably the ideal pace. More than any single sight, the trail itself, the rhythm of road, bridge and ferry, is the attraction.

Bengtskär is the tallest lighthouse in the Nordic countries, a granite-and-brick tower standing alone on a bare skerry far out in the open Baltic, southwest of the archipelago proper. Built in 1906, it survived heavy fighting in the Second World War and now welcomes visitors who climb the tower for vast, exposed sea views, tour the keeper's quarters and small museum, and even stay overnight in the simple rooms. Getting there is part of the experience: a boat trip across open water from Kasnäs or Hanko in summer, weather permitting. The sense of remoteness and the drama of the setting make it one of the most memorable places in the region.

Örö is one of the archipelago's most fascinating islands, a former closed military base opened to the public only in the last decade and now part of the Archipelago Sea National Park. It pairs a century of coastal-defence history, gun batteries, barracks, ammunition stores and a narrow-gauge railway, with surprisingly rich nature, including rare plants and butterflies along its long, narrow length. Marked trails run from the harbour to the southern tip, and you can day-trip or stay overnight in the old barracks. Reached by ferry from Kasnäs, it feels genuinely off the beaten track while still being accessible, a rare combination in the region.

Nauvo (Nagu in Swedish) is the liveliest hub on the Archipelago Trail and the social heart of the inner archipelago, a pretty bilingual village built around a medieval stone church and a busy summer guest harbour. In season the harbour fills with sailing boats and the quayside cafes, restaurants and shops buzz late into the long northern evenings, while the surrounding lanes and shoreline stay calm and traditional. It is the natural place to base yourself, eat well and break the journey, with good connections onward to Korpo and the outer islands. The mix of maritime bustle and old-village charm is exactly what people picture when they imagine the archipelago.

The sheltered, island-studded waters of the Archipelago Sea are among the finest places in Europe to kayak and potter about by small boat. The maze of skerries breaks up the wind and waves, so the inner archipelago stays calm enough for beginners, and you glide past bare rocky islets, red-painted boathouses, basking seals and seabirds, often with nowhere else in sight. Guided trips run from several islands and range from a few hours to multi-day expeditions with island camping, and operators provide gear and instruction. Getting out on the water, rather than just driving between islands, is the way to feel the scale and quiet of the place.
