Whether you crave solitude, awe-inspiring vistas, or a true test of endurance, the UKK Trail offers a quintessential Arctic hiking experience in one of Finland’s greatest wilderness areas.
Route Overview
The UKK Trail begins near the village of Kiilopää, situated on the western edge of Urho Kekkonen National Park, and typically finishes at Raja-Jooseppi near the Russian border to the east. Spanning approximately 100 kilometers, this point-to-point route traverses some of the most remote and unspoiled areas of Finnish Lapland. Key locations along the route include the scenic valleys of the Soma and Kemi Rivers, the open expanses of the Rautujärvi wilderness, the tranquil shores of Luirojärvi Lake, and the opportunity to summit Sokosti, the highest fell in the park. The trail passes through several wilderness hut sites and designated campsites, with sections occasionally offering the chance to observe cultural sites related to the Sámi people.
The hike generally takes 6–8 days to complete, depending on pace and route variations. Trail conditions range widely and can include rocky ridgelines, soft tundra, dense pine forests, and boggy wetlands. Markings are present on the main trail but can be sparse or fade in certain sections, making reliable navigation tools essential. There are no shops or formal resupply points along the trail, so hikers must carry all supplies needed for the journey. Accommodation options include open wilderness huts, basic shelters, and plenty of wild camping sites, each offering a distinct wilderness experience. Water sources are plentiful from rivers and lakes, though purification is recommended. The route is best attempted from late June to early September when trail conditions are at their most reliable.
History and Origins of the UKK Trail
The UKK Trail is named after Urho Kekkonen, one of Finland’s most prominent presidents, who served from 1956 to 1982 and was an avid advocate of the country’s wilderness areas. In honor of his commitment to nature conservation, both the national park and the long-distance hiking trail bear his name. The trail was established in the 1980s to celebrate Kekkonen’s legacy and to promote sustainable interaction with Finland's northern wilderness.
Much of the UKK Trail crosses land traditionally accessed by the Sámi people, the indigenous communities of northern Scandinavia. For centuries, the region’s networks of rivers, forests, and open fells have been essential for Sámi reindeer herding, fishing, and seasonal migrations. Hikers on the UKK Trail often traverse ancient Sámi paths, and evidence of traditional livelihoods can still be found, from old shelters to historical reindeer fences.
Over the years, the trail has gained a reputation as one of Finland’s premier long-distance routes, drawing both local and international adventurers. The UKK Trail is not just a passage through scenic landscapes, but also a living link to the cultural and natural history of Finnish Lapland.

Challenges to expect
The UKK Trail covers a vast expanse of remote wilderness, demanding a high level of self-sufficiency and resilience from hikers. Long stretches may lack marked paths, especially in more rugged or marshy areas, making navigation challenging even for experienced trekkers. Carrying detailed maps or a GPS device is highly recommended, as cell service is unreliable through much of the route.
Weather in Finnish Lapland can be unpredictable, with rapid changes in temperature and frequent rain, even in summer and autumn. Cold nights, sudden downpours, and persistent mosquitoes in warmer months can add to the difficulty. Snow patches may linger on higher ground well into the early summer, and slippery or boggy conditions are common after rainfall.
There are few convenient resupply points, so hikers must plan food and gear provisions carefully to last multiple days between settlements. Water is generally abundant but may require purification. The terrain alternates between rocky slopes, dense forests, and wet lowlands, which can make progress slow and physically demanding. Proper footwear and the ability to handle prolonged isolation are essential for anyone tackling the UKK Trail.
