In 60 seconds
Comprising more than twenty thousand smooth granite islands, islets, and wave-scoured skerries scattered across the Baltic Sea, the Turku Archipelago (Saaristomeri) is the world's largest archipelago by island count. Its defining experience is the Archipelago Trail (Saariston Rengastie), an exhilarating 250-kilometre circular road and cycling route linking major islands via soaring arched bridges and a fleet of free yellow cable ferries (lossi) operated by the state. Anchor towns like bilingual Parainen (Pargas), Nauvo (Nagu), and Korppoo (Korpo) welcome travellers with weathered red boathouses, historic stone churches, and lively guest marinas where yachts moor beneath midnight sun skies. Out on the furthest stormy maritime frontier looms Bengtskär Lighthouse, the tallest lighthouse in the Nordic nations, standing proud upon a bare granite skerry.
