Hailuoto Island

Hailuoto is the largest island in the Gulf of Bothnia, and it is young: it began emerging from the sea about 1,700 years ago as land uplift lifted sandbanks clear of the water, and it is still growing outward at a measurable rate, which means the interior carries old shorelines, dunes and forest at different stages of colonisation. It is low, sandy and quiet, with a few hundred residents, a wooden church, fishing harbours, long empty beaches at Marjaniemi with a lighthouse, and some of the best bird watching in the region on the shore meadows. Until 2026 the crossing was by a free ferry, replaced in cold winters by an ice road; a causeway with two bridges opened on 29 June 2026, so the island is now reached by road.

History

The first parts of Hailuoto rose from the Baltic about 1700 years ago as the land lifted after the Ice Age, and permanent settlement seems to have begun in the 12th century, with people from western Finland and from Karelia; the Swedes called it Karelö, "Karelian island", which became Karlö. The island had 43 houses in 1548 and 60 by 1570, became a parish of its own in 1587, and in 1652 Queen Christina gave the whole island to Colonel Berndt Taube, whose heirs returned it to the crown in 1675. Its church, built in 1610-1620, was long the oldest wooden church in use in Finland until it burned in 1968, and the present church was completed in 1972 (Wikipedia, Hailuoto).

What's there

• An island still rising from the sea - old shorelines inland from the coast.
• Marjaniemi lighthouse and beaches - the western point of the island.
• Shore meadow bird watching - waders and geese on the flats.
• The winter ice road - the crossing when the sea freezes hard enough.

When to go

May to September for the beaches and birds; February and March if you want the ice road, which is not guaranteed in any given winter. A day or two.

Things to know

The ice road depends entirely on the winter and is not open every year. Services on the island are minimal and many close out of season. It is flat and quiet with little to do beyond walking and birds. Mosquitoes are heavy in midsummer.
