Hiking in Finland: trails, national parks and tips for every season

Start with how long you want to be out, then match the trail to your experience level.

Trails in Finnish national parks are rated from easy to demanding. Easy routes are well-surfaced and manageable for families and beginners; demanding routes involve longer distances, rougher terrain and sections without duckboard underfoot. Check your chosen route's rating at luontoon.fi before you set off – and always check the weather forecast, too. Finnish weather might have strong opinions and isn't shy about expressing them, especially in Lapland. A rain shower or heavy winds at the fells can come by unexpectedly.

Finland's most celebrated long-distance trails are worth knowing by name. The Karhunkierros (the Bear's Trail) runs 82 kilometres through Oulanka National Park, spanning the Salla and Kuusamo areas, taking in canyons, roaring rapids, suspension bridges and old-growth pine forest along the way. It is widely considered the finest long-distance hiking trail in Finland. The Hetta-Pallas Trail in Pallas-Yllästunturi National Park covers 50 kilometres across the western fells of Lapland, rolling over open fell terrain and down into sheltered birch ravines ("kuru" in Finnish), with wilderness huts spaced neatly for overnight stops. The Pyhä-Luosto Trail in central Lapland links the two fell areas of Pyhä and Luosto within a single national park, passing through ancient spruce forest, with good transport connections at both ends.

For accessible hiking, luontoon.fi has a dedicated filter for accessible routes and destinations across the country.

The honest answer is that every season has something genuinely good to offer. It just depends on what you're after.

Summer (June-August) gives you the longest days and the most comfortable conditions, particularly in the south and centre of the country. In northern Lapland, the midnight sun means you can hike at any hour you like, which sounds strange until you're actually doing it at 2am and wondering why you ever stopped. This is peak season on popular trails like Karhunkierros, so book any reservable huts well in advance. Mosquitoes can be an issue in certain areas.

Autumn (September-October) is the season Finns tend to love most, and once you've seen it, you'll understand why. The ruska season – the birches, rowans and Arctic plants turning to gold, orange and deep red – peaks in Lapland around mid-to-late September. Nights are cooler, trails are quieter than in July, and the Northern Lights begin to appear as the darkness returns. It is, in short, a very good time to be on a fell.

Spring (April-May) brings snowmelt, birdsong and the particular joy of watching Finland shake off winter – but also wet (or ice), soft trails and potentially high river levels depending on your location. Check conditions before setting out, especially in the north.

Winter hiking is a real thing in Finland, but it's a different undertaking entirely. Snowshoes, proper insulated layers and experience navigating in cold conditions are all essential. Some trails, like Kevo Canyon, are only accessible between June and October. Always check the weather and the seasonal access at luontoon.fi before planning a winter route – and preferably go with a local expert.

Finland's trail network comes with a well-maintained system of places to stop, rest and sleep – much of it free.

Open wilderness huts ("autiotupa") are free to use on a first-come, first-served basis and built for a single overnight stay. They typically have sleeping benches, a stove and firewood. A warning for peak season: on popular routes like Karhunkierros in summer, they fill up fast. Carrying a lightweight tent as backup is always a good idea.

Rental huts can be booked in advance at eraluvat.fi for a small nightly fee. Metsähallitus manages over 100 rental and shared rental huts throughout Finland, especially near national parks and hiking areas. These are especially worth securing for the ruska season.

Lean-to shelters ("laavu") are open-sided wooden structures with a campfire spot, found at regular intervals along most marked trails. Free to use, excellent for lunch, and one of the small pleasures of hiking in Finland.

Visitor centres in national parks often have a café, maps, trail conditions information and staff who know the area well.

Your own gear gives you the most flexibility on longer routes. A lightweight tent means you're not dependent on hut availability, and on a remote trail that independence is worth a lot.

Always follow Everyman's Rights and Leave No Trace principles – pack out your rubbish, use designated campfire spots and leave rest areas as you found them.
