Oulanka National Park, located in Northern Ostrobothnia and Lapland, was established in 1956 and currently spans approximately 270 square kilometers. The park is celebrated for its unique blend of Arctic, boreal, and southern flora, making it a significant hotspot for biodiversity. Its emblem is the rare Calypso orchid, which thrives in the region's lime-rich soil. Geographically, the area is defined by the powerful Oulankajoki and Kitkajoki rivers, which flow through deep canyons and create spectacular rapids such as Kiutaköngäs. The park is home to Finland's most popular hiking trail, the 80-kilometer Karhunkierros (Bear's Ring). Beyond its rich plant life, Oulanka provides habitat for reindeer, brown bears, and numerous rare bird species. The visitor center provides detailed insights into the complex river ecology and the geological history of this distinctive landscape.

🧭

Getting there

📅

Best season

Summer is traditionally the peak season for hiking the famous Bear's Trail, when the river landscapes are particularly spirited. The Finnish autumn brings spectacular foliage colors, while winter provides entirely different, snow-covered impressions.

⛰️

Terrain & paths

The extensive park terrain provides a varied mix of dense forest paths, swaying suspension bridges, and spectacular riverbanks. The popular Bear's Trail encompasses both easy passages and physically demanding ascents and descents along the route.

🎒

What to bring

Those planning longer sections of the Bear's Trail require full trekking gear, including a tent and sufficient provisions. For day trips along the river landscapes, sturdy hiking boots, insect repellent, and a good daypack are usually sufficient.

🅿️

Parking

At the central visitor centers near Kuusamo, there are usually large, well-signposted parking lots available for both day and multi-day guests. Because the park is highly popular, arriving as early as possible in the day during peak months is recommended.

⚠️

Safety

Completing the Bear's Trail requires a good assessment of one's abilities and plenty of drinking water, as the distances are considerable. Rivers should usually only be crossed using the designated bridges and crossings to avoid any unnecessary accidents.

⏱️

Time needed

Day visitors can usually explore individual scenic highlights and river sections within a few hours. However, anyone wishing to hike the entire Karhunkierros route must typically plan for several consecutive days of dedicated and challenging trekking.
