Finland has 40 national parks, free entry to all of them, and a legal right called Everyman's Right (Jokamiehenoikeus) that lets you camp, walk and pick berries on any land — public or private — without asking permission. The flagship Karhunkierros Bear Trail covers 80 km of gorges, suspension bridges and glacial rapids in Oulanka National Park over 5 to 7 days, while Lapland's open fell routes offer the best September hiking on the continent.
Finland's Hiking Infrastructure: What Makes It Different
Finland does not charge national park entrance fees, does not require trail permits for any of its 40 parks, and maintains a network of wilderness huts (autiotupa) that are free for up to two nights on a first-come basis. This is not a cost-cutting measure — it is the result of the Jokamiehenoikeus, a constitutional right of free movement and access to nature that has been embedded in Finnish law for centuries. The practical effect is one of Europe's most accessible backcountry hiking networks, with 17,000 km of marked trails across parks ranging from the boreal forests of southern Finland to the Arctic fell landscapes of Lapland. Compare this to Sweden's Kungsleden — covered in our Kungsleden guide — or Iceland's Laugavegur Trail: Finland is less dramatic in scenery but far more accessible and significantly cheaper.
Karhunkierros (Bear's Ring Trail): Finland's Most Famous Hike
The Karhunkierros runs 80 km through Oulanka National Park in northern Finland, starting from either Hautajärvi in the north or Ruka fell resort in the south. Marked with orange paint blazes, it passes through the Oulanka River gorge — a series of 15–20 m deep canyon sections with swinging suspension bridges and rapids — and crosses open fell plateau above the tree line. Most hikers complete it in 5 to 7 days at a relaxed pace covering 12–18 km daily.
- Distance: 80 km south to north (or reverse)
- Total ascent: ~1,200 m — modest compared to Alpine routes
- Trail surface: Mix of boardwalk (over boggy sections), rocky gorge paths and open fell
- Wilderness huts: 9 along the route, free, first-come-first-served (max 2 nights)
- Reservable lean-tos: Available at Oulanka Visitor Centre, Kuusamo; ~€20/night
- Mini Bear's Ring: A 13 km day-hike shortcut through the gorge section — the most spectacular 4 hours on the full route
The best single section of the Karhunkierros is the 18 km stretch from Juuma to Oulanka Visitor Centre, which contains all the major suspension bridges (including the 54 m Jyrävä span above the rapids), the Kiutaköngäs falls (Finland's most photographed waterfall) and the deepest canyon section. Day-visitors from Kuusamo town (30 km away) can access this section as a car-drop day trip.
Lapland's Best Hiking Routes: Fell Country Above the Tree Line
Above 69°N, the Finnish landscape opens into treeless fell (tunturi) — rolling Arctic plateau covered in dwarf birch, heather and lingonberry. This is the terrain that makes late-September hiking in Lapland exceptional: the ruska (Finnish autumn foliage) turns the fell into a continuous orange-red carpet, temperatures drop to 2–8°C during the day, and the crowds of summer have entirely dissipated.
- Pallas-Yllästunturi National Park: Finland's third largest park, with 120 km of marked trails and the classic Hetta-Pallas hike (56 km, 4–5 days) crossing open fell from Hetta village to Pallastunturi fell resort. No technical difficulty; excellent hut network with reservable accommodation.
- Urho Kekkonen National Park (UKK): Finland's largest park at 2,550 km², adjacent to the Russian border near Saariselkä fell resort. The wilderness zone has unmarked routes requiring map-and-compass navigation. Marked day trails from Kiilopää fell centre are suitable for all levels.
- Lemmenjoki National Park: Finland's largest national park by area (2,855 km²), accessed by boat along the Lemmenjoki river. Virtually no visitor infrastructure — for experienced wilderness navigators only.
Season Guide: When to Hike Finland
| Period | Conditions | Mosquitoes | Daylight | Recommendation |
|---|---|---|---|---|
| Late May–June | Wildflowers, snow patches on fell | Heavy (especially June) | Midnight sun in Lapland | Bring full head net and DEET |
| July | Warmest, green fell | Moderate to heavy | 20+ hours in south | Good; head net essential |
| August | Berry season begins, warm days | Light | 16–19 hours | Excellent; pick blueberries and cloudberries |
| September | Ruska foliage, crisp and clear | None | 12–16 hours | Best month for Lapland hiking |
| October | First snow in Lapland, rapidly shortening days | None | 8–12 hours | Southern parks only; Lapland not recommended |
Gear for Finnish Trail Conditions
Finnish weather is unpredictable in all seasons. Rain can arrive on any August day; September nights drop to 0–5°C in Lapland. The layering system matters more than any single piece of gear — see our hiking layering guide for the complete approach. For the outer layer on the Karhunkierros and Lapland routes, the Black Diamond Stormline Stretch Rain Shell (295 g) handles the drizzle and wind that comes off the open fell without the bulk of a heavier Gore-Tex jacket. For Lapland September camping, the Katabatic Gear Sawatch 15F Quilt provides comfort to -9°C — appropriate for fells that can dip to -3°C in late September — at a pack weight of 595 g. For sheltering on the many boggy lake-shore campsites along the Karhunkierros, the NEMO Hornet OSMO 2P (1,080 g) freestanding pitch is particularly useful when rocks for trekking-pole guylines are scarce in the flat boreal forest terrain.
Getting to Oulanka and Finnish Lapland
For the Karhunkierros: fly to Kuusamo Airport from Helsinki (1 hour, Finnair and Nordic Aviation; €80–€140 return). Kuusamo is 30 km from the Oulanka Visitor Centre. Car rental from Kuusamo is the most practical onward transport option; taxis cost approximately €35 to the trailhead. For Lapland parks: fly to Rovaniemi or Ivalo from Helsinki. The Finnish National Parks website (nationalparks.fi) has up-to-date hut booking, trail conditions and camping zone maps for all 40 parks.
Frequently Asked Questions
Is the Karhunkierros Bear Trail suitable for beginners?
Yes — the Karhunkierros is suitable for fit beginners with basic hiking experience. Total ascent is only ~1,200 m across 80 km and the trail is fully waymarked. The main challenges are the distance (80 km over 5–7 days), variable weather and, in June–July, mosquitoes. Navigation requires only following orange paint blazes and occasional information boards.
Can you drink water directly from streams in Finnish national parks?
Water quality in Finnish national park streams is generally excellent — Finland has some of the cleanest freshwater in Europe. However, reindeer grazing occurs throughout Lapland and can introduce bacteria. The official advice from Metsähallitus (the Finnish parks authority) is to treat all water, particularly near reindeer pasture areas. A filter like the Sawyer Squeeze or Katadyn BeFree adds negligible pack weight and eliminates the risk.
What permits do you need to hike in Finnish national parks?
No permits are required for any Finnish national park trail. Day visits, overnight camping and use of free wilderness huts are all permit-free. Reservable huts (~€20–€25/night) require advance booking through the Eräluvat online system (eraluvat.fi). Fishing and hunting require separate licences; wildlife viewing, foraging and hiking are unrestricted under Jokamiehenoikeus.
Are there bears in Finnish national parks?
Yes — Finland has approximately 2,800 brown bears, and Oulanka National Park (home of the Karhunkierros) has a resident bear population. Encounters on the trail are extremely rare; bears actively avoid humans. Standard precautions apply: make noise while hiking, store food in bear-proof containers or hanging from trees at camp, and do not leave food waste near tent sites. Bear spray is legal in Finland but not commonly carried by day hikers.
What is the ruska, and when is the best time to see it in Lapland?
Ruska is the Finnish word for autumn foliage — the period when Arctic fell vegetation (dwarf birch, bearberry, lingonberry) turns from green to gold, orange and deep red. It typically peaks in mid-to-late September in northern Lapland (above 68°N) and early October in southern Lapland. The Pallas-Yllästunturi National Park ruska is considered the most spectacular in Finland; Pallastunturi fell viewpoints on a clear September day show unbroken horizon-to-horizon colour.
