When people ask us what the most spectacular trail in Finland is, we don’t hesitate. The Karhunkierros trail — the Bear’s Ring — in Oulanka National Park is in a different league from anything else in the country. We live in Rovaniemi, 90 kilometres to the northwest, and we’ve driven down that road more times than we can count: for day walks, for weekend circuits, and once for the full 82-kilometre through-hike that took us four days and left us wondering why we hadn’t done it years earlier.

Summer is Oulanka’s prime season. The rivers run full, the suspension bridges sway above whitewater gorges, the meadows bloom in a way that feels impossibly lush for this latitude, and the sun barely sets. It’s busy — this is the most-visited national park in Finnish Lapland — but manage the timing and you can still find sections that feel genuinely wild.

What the Karhunkierros trail actually is

The Karhunkierros — Bear’s Ring in English — is an 82-kilometre marked trail that loops through Oulanka National Park and the adjacent Kiutaköngäs rapids area in northern Finland, about 250 kilometres north of Oulu and 90 kilometres southeast of Rovaniemi. It’s consistently ranked among the finest long-distance trails in the Nordic countries, which is a high bar.

What makes it different from other Finnish trails

Most of Finland is flat. Oulanka isn’t. The Karhunkierros runs through a series of dramatic river canyons carved by the Oulankajoki and Kitka rivers, crossing gorges on suspension bridges, climbing through old-growth boreal forest, and traversing open fell meadows — all in a landscape that feels more like Norway than typical Finnish terrain. The rivers here are a vivid turquoise-green fed by upland peatlands, and the gorge sections are genuinely spectacular.

The short loop vs the full trail

• Full Karhunkierros (82 km): Starts at Hautajärvi visitor centre in the north and ends at Juuma (or reverse). Takes 4–6 days. The complete wilderness experience.
• Pieni Karhunkierros / Short Loop (12 km): A circuit from Juuma in the south. Crosses two suspension bridges, passes the Jyrävä waterfall, and gives a taste of the full trail in half a day. This is what most visitors do — and it’s genuinely stunning.
• Partial sections (2–3 days): Start at Juuma and hike north to Oulanka Visitor Centre or Särkitunturi fell area, then arrange a ride. Gives you the best southern canyon sections without the full commitment.

How to plan your summer Karhunkierros hike

The trail is not technically difficult — no glacier, no via ferrata — but it is long. Planning matters here. Here is how we think about it.

Step 1 — Pick your dates

Mid-June to late August is the best window. The trail is snow-free, the huts are open (most are free to use on a first-come basis), rivers are high but passable, and the midnight sun gives you extra evening light. July is the busiest month — the most popular huts fill up. Late June and late August are the sweet spots: good conditions, fewer crowds.

Step 2 — Decide on direction

Most people hike south to north (Juuma to Hautajärvi) because transport is easier to arrange at Hautajärvi. We prefer north to south (Hautajärvi to Juuma) because you tackle the more remote northern sections while your legs are fresh, and you finish at Juuma where there is a small shop and a proper sauna.

Step 3 — Sort transport

There is no public transport to either trailhead from Rovaniemi or Kuusamo. Options: rent a car and leave it at one end (taxi or pre-arranged ride to the other); join an organised guided hike; or stay at the Juuma camping area where taxis can be called from Kuusamo (about 40 km south).

Step 4 — Register your hike

Finland’s national park huts are free and do not require advance booking, but it’s smart to let someone know your itinerary. Metsähallitus (Finnish Parks and Wildlife) has a route-planning tool at outdoors.fi. Download offline maps before you go — phone signal is patchy in the canyon sections.

Section-by-section: the Karhunkierros from Hautajärvi to Juuma

Here is the practical breakdown of the full trail split into day-stages. Distances are approximate; your actual pace will depend on how long you linger at the viewpoints (answer: longer than you planned).

• Day 1 — Hautajärvi to Taivalköngäs (18 km): Open fell landscapes give way to the first canyon section. The Taivalköngäs hut sits above a roaring rapids — stay here even if you arrive early. It fills up in July.
• Day 2 — Taivalköngäs to Oulanka Visitor Centre (16 km): Some of the best canyon walking on the trail. The Kiutaköngäs rapids are the most powerful in Finland — the roar is audible from 500 metres. The visitor centre has a café and gear shop.
• Day 3 — Oulanka Visitor Centre to Purmajoki (14 km): Shorter day. Cross the famous Oulankajoki suspension bridge, then follow the river south through old-growth spruce forest. Purmajoki hut is peaceful and often less crowded than the ones further north.
• Day 4 — Purmajoki to Savinajoki (16 km): The middle section has some of the most remote feeling terrain. Multiple river crossings on stepping stones and small bridges. Meadow sections bloom with wildflowers in late June.
• Day 5 — Savinajoki to Juuma via Jyrävä Falls (18 km): The finale. Jyrävä waterfall is the trail’s most photographed spot — earn it. The last kilometres into Juuma follow the Kitkajoki river. End with a swim in the lake at Juuma camping area.
