Description
Jatkonvalkea is the shortest of the four marked mountain-bike routes in Hossa National Park, rolling through lake-and-ridge scenery between the Pikku-Hossa services area and Hossa Nature Centre in Suomussalmi. The trail is about 7.1 km long as one continuous ride on our map, a point-to-point line rather than a closed loop, and it is pitched in regional tourism copy as the easiest option for newcomers who want to sample Hossa by bike. For national-park cycling rules, maps, GPX downloads, and the wider MTB network, Metsähallitus publishes the Hossa mountain-biking hub on Luontoon.fi. Visit Suomussalmi’s Jatkon valkea page stresses gentle gradients, white trail markings, and views along Huosivirta, Jatkonsalmi, and Jatkonjärvi. MTBreitti.fi’s Hossa overview reminds riders that mountain biking is only allowed on routes posted for cycling—staying on those marked corridors keeps the rest of the park habitat protected.
You begin near the Pikku-Hossa cluster, where Pikku-Hossa ulkotulipaikka, the small Laituri Pikku-Hossa, reservable Pikku-Hossa vuokratupa, and dry toilets make it easy to sort gear before pedalling toward the straits. At Jatkonsalmi the route passes a campfire spot, reservable Jatkonsalmi, Teräväpää vuokratupa and Jatkonsalmi, pääpirtti vuokratupa, the JATKONSALMI laituri paddling dock, and Jatkonsalmen esteetön melontalaituri—useful if you are combining biking with a chat about the adjacent Nurmiselkä–Jatkonjärvi paddling corridor or Sininen saavutus, which shares this end of the park.
Along Jatkonjärvi you soon reach several Jatkonjärvi tulentekopaikka stops, Jatkonjärven esteetön laituri, and Jatkonjärven telttailualueelle parkkipaikka for anyone staging a tent night beside the water; dry toilets sit nearby at Jatkonjärvi käymälä nro 1, Jatkonjärvi käymälä nro 2, and Jatkonjärven esteetön käymälä. About 4 km in, Mykräsalmi hete marks a short spring line before the trail works toward Huosivirta tulentekopaikka and Huosivirta pysäköintipaikka—an outing hub with its own Huosivirta p-paikka käymälä. The northern arc touches Torkonluikea tulentekopaikka on a quieter forest bench before you curve back toward the Keihäslampi and Huosilampi shoreline playgrounds: Keihäslampi pysäköintipaikka, Keihäslampi tulentekopaikka, Keihäslampi laituri, Huosilampi invalaavu, Huosilammen invakatos, multiple Huosilampi laituri landings, and Huosilampi tulentekopaikka with a nearby Huosilampi tulentekopaikka käymälä. Hossan luontokeskus and Luontokeskus pysäköintipaikka finish the line, putting you beside Öllöri laituri and the interpretive desks where fatbike hire is coordinated in season. A Ylä-Kainuu piece with Metsähallitus field staff notes routine maintenance and modest wear on the bike trails going into summer 2023—worth checking before you pack tools.
Kainuu is known for clear-water lake country; Suomussalmi anchors the western approach to Hossa. If you want a short detour by car, Visit Suomussalmi suggests the Lounatkoski mill area off Tolosenvirrantie as an extra cultural stop near the same holiday belt.
Length & route
About 7.1 km end to end on the stored geometry, beginning near Pikku-Hossa and finishing at Hossa Nature Centre. Promotional trail lists often round to roughly 10 when they assume a nature-centre start or when a brochure counts slightly wider connectors; use the 7.1 km figure when you match this exact trace. Expect modest ridge-and-lake rollers rather than long sustained climbs.
Getting there
If you aim for the nature-centre trailhead, drive to Jatkonsalmentie 6, 89920 Suomussalmi, use Luontokeskus pysäköintipaikka or the wider nature-centre parking, and pick up paper maps during opening hours. Riders linking from Sininen saavutus or the Pikku-Hossa camping and rental cabin belt can roll in from that eastern cluster instead, using Jatkonjärven telttailualueelle parkkipaikka or Huosivirta pysäköintipaikka when you need a staged start. Metsähallitus publishes public-transport and park-access context from the main Hossa destination pages on Luontoon.fi.
Good to know
Carry mud-capable tyres after wet weeks; boardwalks appear along wetter lake edges but soft shoulders still occur. Dogs, campfires, and Everyman’s Rights nuances follow Hossa National Park bylaws—confirm the latest wording on Luontoon.fi before lighting stoves or letting dogs range. Winter riders often switch to fatbikes on maintained corridors; summer mountain bikes stay on the signed MTB network.
Where to rent bikes
Hossa Nature Centre contracts Trek fatbike hire through the Hossa–Kylmäluoma visitor co-operative: email hossa@retkeilykeskus.fi or call +358 50 384 4692 to reserve frame sizes, and collect bikes when Luontokeskus is staffed. Visit Suomussalmi explains that the shortest marked option, Jatkon valkea, is the gentle introduction while Sininen saavutus is the headline endurance loop, and it points riders to Luontoon.fi for PDF maps.
Ride comfortably in either direction between Pikku-Hossa and Hossa Nature Centre; Visit Suomussalmi still describes Luontokeskus as the primary trailhead even though our geometry begins from the Pikku-Hossa cluster. Linking riders often continue onto Sininen saavutus for a full-loop day.

Terrain & conditions
7.1 km
Distance
Allow about 1–2 hours for the 7 km profile at a relaxed sightseeing pace with short photo stops; beginners should budget closer to two hours when pausing at shelters.
Est. Time
Mixed forest gravel and smooth singletrack between lakes, with short boardwalk-style crossings where shoreline bogs stay damp; a compacted liaison ties Huosivirta and nature-centre access roads into the wilder middle section.
