From lively coastal villages to secluded lighthouses, thrilling bicycling routes and kayaking waters, national parks and inhabited islands, the Finnish Archipelago Sea has it all. With more than 40,000 beautiful islands scattered across the sea, this is the world’s largest archipelago, and there are plenty of hidden gems to be discovered. The Archipelago Sea stretches from southwest Finland out into the Baltic Sea, all the way to the Åland islands more than halfway to Sweden. From Helsinki you reach the Archipelago Sea by bus or car in less than two hours, and from Turku harbor or airport you get to the archipelago islands in 30 minutes.
