Trail Description
Length: 50 km
Trail markings: blue signs
Starting point: visitor centre, the starting point for mountain biking trails
Direction: anti-clockwise
The Sininen saavutus Trail runs in almost all parts of the national park, utilising its extensive network of trails. Only the Ala-Ölkky and Julma-Ölkky areas are not located along the trail. The trail runs by the Värikallio area. From the Lihapyörre area, it runs along the same trail from which branches off a connecting trail to Värikallio. Please note, in summer it is not allowed to cycle to Värikallio. Leave your bike for a while and have a walk to the Värikallio Cliffs.
You can cycle the entire circle trail in one day, if you already have some mountain biking experience. In other words, you do not need to be particularly experienced. However, the trail is long and its technical elements are demanding in places. As regards its technical elements, the trail as a whole is intermediate. On a long trail, the weather is important. In rainy weather, the trail becomes a couple of categories more demanding on its technical sections, because of the wet roots. Likewise, the final part of the trail in the area of Jatkonvaara Hill may be very challenging. Of course, you can also set off from elsewhere than from the visitor centre, even though it is the official starting point. You can also shorten the trail at many points.
Initial Part Starting from the Visitor Centre
The initial part of the trail runs along the yellow trail, all the way to a trail that connects Lake Syvä-Suottajärvi and the Hakokoski Rapids. From there, the trail continues along the shores of Lake Syvä-Suottajärvi to Lake Puukkojärvi. The trail continues along the shore of Lake Puukkojärvi to Talassalmi. The Puukkojärvi lean-to shelter is located in this section. From Talassalmi, continue along the shores of Lake Talasjärvi, to Laukunsalmi. At Laukunsalmi, you will arrive at crossroads of trails, from where you can branch off to the Laukkujärvi Open Wilderness Hut.
The trail turns to the left towards Laukunsalmi and runs across a bridge, to the southwestern shore of Lake Laukkujärvi. After pedalling about 250 metres, turn to the left and ascend to a skiing trail base that runs along the esker, and continue to the Lihapyörre parking area. From there, the trail continues along a more stony connecting trail (that runs to the Värikallio Cliffs, where is forbidden to ride a bike in summer), until it branches off from the connecting trail and continues straight towards Laurintyrnänlampi Pond and Levälammet Ponds. This trail section consists of small-scaled, more technical root-filled terrain, where bikers are able to test their biking techniques.
Towards Lake Kokalmus
After crossing Pistonlehdontie Road, the trail continues from the southwestern side of Kirkasvetinen Pond to Kaunislampi Pond. This is also a more technical, root-filled section. After Kaunislampi Pond, the trail becomes easy and continues towards Valkeisenvaara Hill and Lake Kokalmus. By the Kokalmus reindeer shed, the trail turns to the right towards the Kokalmus lean-to shelter.
The trail running along the shore of Lake Kokalmusjärvi is undulating, even though there are also some roots on the terrain. After Kuikkalahti, there will be several duckboard sections that can be cycled. Thereafter, you will arrive at a reindeer shed that is located close to the Kokalmus lean-to shelter. After bypassing it, you will arrive at a lean-to shelter that is located at a tip of a small peninsula in the Korealahti Bay.
Towards the River Aittojoki, via Syrjäharju Esker
From the bottom of Korealahti Bay, turn to the right and start ascending, along a maintenance road, until you arrive on a forest road that runs to Pistonlehdontie Road. The trail continues along the road for about 5.5 km until you arrive at Alakoski, River Aittojoki, on the western side of Variskangas. Before the bridge across River Aittojoki, turn to the left onto a small, undulating trail along the riverside. By the pond on the edge of a mire area, you will be able to enjoy the loud mating concert of birds when pedalling towards the shore of Lake Lavajärvi. Before Likolahti, turn to the left and continue to the Syrjäsalmi lean-to shelter and to Syrjäharju Esker.
After crossing the Syrjäsalmi bridge, you will ascend to Syrjäharju Esker. The stony trail takes you, along the narrow ridge, to the east, and you will see the Iso-Nimetön watercourse on your right side. Thereafter, the trail turns and descends to the right just before Nimettömänsalmi. The undulating trail that runs along the shores of Pikku-Nimetön goes across streams and bypasses moister sections. Then you will arrive at the Joukovirta lean-to shelter. After the Joukovirta lean-to shelter, the trail takes you to the shore trails of Lake Joukojärvi and to the side of Virtasalmi. Thereafter, there is a fairly steep ascent. Continue along a trail that goes towards a former reindeer roundup pen. The trail descends towards Poroaidanlampi Pond. After riding round the pond, there will be a brisk ascent, and you will arrive at the trail section on the western side of Lake Lounat-Valkeinen. This trail is much more stony and unlevel all the way to the shore sections on the western side of Lake Lounaja. After the Rytipuro duckboards, you will arrive at a trail that connects Lake Kokalmusjärvi and Lipposensalmi. Next, you will arrive at the Lipposensalmi bridge and an idyllic lean-to shelter.
From Lipposensalmi towards the Visitor Centre
The trail continues along the southern side of Lipposenniemi to the shore trail of Lake Lounatkapea. Thereafter, it turns to the left to a small-scaled, more technical trail that takes you onto Jatkonvaara Hill. You will arrive at the top of Jatkonvaara Hill after a two-kilometre ascent. Thereafter, the trail starts descending towards Pistonlehdontie Road, connecting to the white trail. After crossing Pistonlehdontie Road, continue towards the Huosivirta parking area. The final section goes along Jatkonsalmentie Road to the visitor centre.
