Urho Kekkonen National Park

In Sompio Strict Nature Reserve, 2 or 7 km. A return trip to the Pyhä-Nattanen fell or a circle trail including Pyhä-Nattanen. The day hut on the fell was built as fire watch hut. On the circle trail there is also a lean-to shelter, at Nalijoki. The circle trail starts at the information board, the return trip 1.1 km farther by the road. The fell is rough and steep enough not to suite people with health or fitness issues: stone fields where hiking boots or good balance is needed and a 200 m ascent on 1 km. Nice views from the peak.

5-km circle trail. Through the fell birch forest to the slopes of Ahopää with some views to Kiilopää, with information boards telling about the reindeer. Quite easy terrain, but some meltwater-eroded stretches.

15-km circle trail mostly along gravel roads, featuring the gorge Rumakuru (watch out for avalanches and rock falls). Day huts at Rumakuru and Piispanoja.

16-km circle trail with varying landscapes. Starts by climbing the fell Iisakkipää, with good views, then descends to follow Pääsiäiskuru, climbs a hill and then more or less follows Tammukkaoja to Vellinsärpimä. The Vellinsärpimä day hut is a good place to eat your dinner – or overnight in tents if you take it easy. Continue to the north-east and turn right after half a kilometre, towards Luttotupa. Turn left after a kilometre, to the Moitakuru trail. You then follow the river Lutto to the ski lifts. The trail is not signposted as such, but combines other signposted routes – be careful at junctions.

22.5-km circle route along the slopes of Kiilopää and on to the lake Rautulampi. Popular also by mountain bikers. Magnificient views from Niilopää and Rautupää (the trail goes higher than the maintenance road). Some quite steep sections, and possibly confusing parallel paths at Rautuvanganoja. Long stretches above the treeline, where weather can change rapidly and fog can reduce visibility drastically. Three day huts: Niilopää, Rautulampi and Luulampi. There are old reindeer separation fences near the Niilanpää hut. After the fells and Rautulampi beyond them, the trail continues among rolling hills below the treeline. The return path is either via Luulampi or by a shortcut before it, both routes climbing Kiilopää.

30-km circle trail with only moderate elevation differences, unless you take the sidetrip to the Iisakkipää summit. Part of the distance is along gravelled paths, but there are also wet and rocky sections. Day hut at Vellinsärpimä, Taajoslaavu is a lean-to. The trail passes a haunted hut, follows Lutto River between the ski slopes and turns to follow Vellinsärpimäoja towards the Vellinsärpimä hut, before which it turns towards Taajoslaavu. This last section towards Taajoslaavu crosses wet terrain. On the way back, the route passes Rumakuru and climbs the slopes of Iisakkipää, optionally visiting the summit.

35 km trail through Sompio to Kiilopää, Kakslauttanen or Laanila, part of the former trail between the Bothnian Bay and the coast of Finnmark (Finnish: Ruija) at the Arctic Ocean. It is mentioned as early as in the 16th century, but fell in disuse at the beginning of the 19th century. This section is now a marked hiking trail. Some of the historic markings (cairns, i.e. stone heaps) remain and must not be touched. The leg through Sompio is tough, with quite rough terrain. As camping is not allowed here, the 15 km leg between Sompiojärvi and the Kaptukaislampi lean-to shelter, with a 2×1.5 km sidetrip to the top of Terävä-Nattanen, has to be done in one day (there is a campfire site for a break before or after the sidetrip). Otherwise there are lean-to shelters 9–12 km (5.5–7.5 mi) apart. The trail crosses the road and some trails of the Kakslauttanen-Kiilopää area, allowing some variations in that end. Sompio is a strict nature reserve, leave no trace and keep to the trail.

2×20 km from Keminhaara to Korvatunturinmurusta, with view to Korvatunturi. Korvatunturi itself is at the border, inside the border zone. See Savukoski.

47 km circle route along Nuorttijoki river at the south-eastern corner of the park, 2×12 km more if you use the UKK trail to get from Tulppio to the trailhead. A new bridge at the far end was built in the autumn of 2020. The ford at Haukinivat is too dangerous at high waters, ask about the current situation at the visitor centre if you intend to cross there on return. If you get stuck on the northern side, continue westward and navigate to the Kemihaara road (6–8 km), you will probably want a taxi to fetch you from there. The far end of the trail is very close to the border zone; be careful the last 2.5 km on the south side (from the Saukkosuvannonvaara shelter) and until the turn on the north side.

70–80 km trail, not marked, but one of the most popular routes, with huts 15–20 km (10–12 mi) apart, with a shorter leg to Luirojärvi, and a few day huts, lean-to shelters and campfire sites for breaks or camping by tent. The four wilderness huts on the trail all have gas stoves for cooking. The trail is mostly along ATV tracks or otherwise wide and easy to follow, but there are some places where you should be alert with your map. There are a few fords, notably Suomujoki at Suomunruoktu, Luirojoki at Luirojärvi, Palovanganjoki by its mouth, and Suomujoki near Lankojärvi. They should be easy, but may be unpassable during spring floods. The fords near Lankojärvi can be avoided by using the Kotaköngäs bridge 2 km upstream from Palovanganjoki (there is a shortcut on higher ground from a campfire site at Palovanganjoki). The Suomujoki crossing at Aitaoja has a bridge, and the ford at Suomunruoktu can be avoided by adjusting the route to ford near its source instead. There is a sauna at Luirojärvi. From Luirojärvi you can visit Sokosti, the highest fell in the area, as a long day trip.

70–80 km trail, also not marked but with huts and campfire sites. In the first part of the route there are buildings of Skolt Sami families, who were evacuated from Petsamo after the war (and later settled at Sevettijärvi. Note the border zone at Raja-Jooseppi.
