About This Anchorage

Nauvo (Swedish: Nagu) is the main population centre and service hub for the inner Turku Archipelago — the largest island in the Nauvon archipelago with a year-round community, school, shops, harbour, and the infrastructure that sustains island life through the winter. The island is connected to Turku by the famous archipelago road — a series of ferries and bridges crossing the inner archipelago channels that forms one of Finland's most scenic road routes. The harbour at Prostvik gives excellent shelter and full facilities: fuel, water, restaurant, and a grocery shop. For sailors heading out to the wilder islands, Nauvo is the last resupply before the true outer archipelago begins.

Skipper's Tips

  • Nauvo is the last proper resupply point before heading to the outer islands — fuel, groceries, and water here before heading to Berghamn or Nötö
  • The archipelago road ferry from Nauvo to Turku is one of Finland's most scenic drives — cycle the route if time permits
  • The harbour restaurant serves excellent local smoked fish and traditional Finnish cuisine at reasonable prices
  • Nauvo church (16th century granite) is one of the oldest intact churches in the archipelago — a 10-minute walk from the harbour
  • The ferry connections mean you can arrange crew changes here if needed — the only reasonable option before Turku
