The world's largest archipelago by island count, with sheltered channels around Pargas, Nagu and Korpo for low-traffic foiling.
The Turku Archipelago counts roughly 50,000 islands, islets and skerries spreading southwest from Turku into the Baltic toward the Aland border. Riding centres on the protected channels around Pargas (Parainen), Nagu (Nauvo) and Korpo, with the Archipelago Trail ferry route giving good access to launches. Brackish water, granite bottom at 5-20 m, almost no swell anywhere inside the inner archipelago, and very low boat density outside the main fairways. Best from late June to early August.
Light southwesterlies 6-12 knots in summer, with hundreds of skerries breaking up swell and providing flat-water lee in any wind direction.
