Hiidenportti National Park is a protected wilderness area in Kainuu, Finland, established in 1982 to conserve its distinctive gorge landscapes and boreal habitats.

The park is noted for a deep rocky gorge carved into ancient bedrock, patches of oligotrophic mires and old-growth forest that support a range of northern flora and fauna. Hiking routes focus on short, rugged loops that pass viewpoints above the gorge and through wetland boardwalks.

The protected area was created by the Finnish state in 1982 to preserve the Hiidenportti ravine and surrounding habitats from logging and drainage. Management has emphasized maintaining natural hydrology and low-impact visitor access.

Hiidenportti sits in the Kainuu region of eastern Finland, inland from the Gulf of Bothnia, within the broader boreal forest zone and near the municipalities that border the park.

  • Trail conditions: Marked trails are short but rugged; expect boardwalks in boggy sections and rocky paths through the gorge.
