Helgøya lies within Lake Mjøsa in Ringsaker municipality, northeast of the town of Hamar on Norway’s largest lake.

  • Largest freshwater island: Recognised as the largest freshwater island in Norway, it is predominantly agricultural with open farmland and orchards, and it is connected to the mainland by road.

Tips for Visiting Helgøya, Innlandet#

  • Drive the island's single main road rather than trying to shortcut across farm fields-local tractors have right of way and the narrow lanes give the best views.
  • Bring binoculars in spring and autumn for migrating waterfowl on Mjøsa; the island's west shore has quieter vantage points.
  • Stop at any farmstand or seasonal stall: Helgøya has an unusually long tradition of vegetable growing-look for local carrots and potatoes.
