Description
Sininen saavutus is an about 49 km marked mountain-bike loop through Hossa National Park in Kainuu, between Kuusamo and Suomussalmi. Metsähallitus publishes route information on the Sininen saavutus page on Luontoon.fi. Visit Suomussalmi’s Sininen saavutus archive entry summarises the layout, lists principal lean-tos and day-use points, and links to a printable Metsähallitus brochure map.
The circuit was named to the international IMBA EPICS list in the 2017 class of new long, mostly singletrack backcountry rides. Tapani Leppänen’s Latu&Polku article explains how mountain biking was written into the park plan from the beginning, with blue markings, maintained fireplaces, and options to shorten the day. Expect a demanding full day: IMBA Europe describes roughly four and a half hours as a minimum time for riders who already have general mountain-bike experience, on rolling esker terrain with many lake outlooks.
Most riders start from Hossan luontokeskus beside Luontokeskus pysäköintipaikka. The first kilometres share the Huosilampi–Keihäslampi shore cluster with Harjujen huikonen and Hossan polku: jetties, Huosilampi invalaavu, campfire spots, and optional parking at Huosilampi pysäköintipaikka, Keihäslampi pysäköintipaikka, or Hossaari parkkipaikka. Around Pikku-Hossa, Pikku-Hossa vuokratupa, Pikku-Hossa ulkotulipaikka, and Laituri Pikku-Hossa sit near Huosivirta pysäköintipaikka and Huosivirta tulentekopaikka. Along Jatkonsalmi you pass Jatkonsalmi, Teräväpää vuokratupa and Jatkonsalmi, pääpirtti vuokratupa. Further along, Tolosenvirta vuokratupa, Lounaja tulentekopaikka, Lipposensalmen laavu, and Syrjäsalmi laavu break up long forest-and-lake sections. Aittojoki pysäköintipaikka supports an Aittojoki tulentekopaikka stop before the route swings toward Kokalmus laavu, Kokalmus tulentekopaikka, and Porotalli; Rytikangas pysäköintipaikka and Kirkasvetinen pysäköintipaikka open northern lakeshore riding toward Lihapyörre laavu and Laukkujärvi autiotupa. The southeast includes Puukkojärvi autiotupa, Puukkojärvi laavu, Hakokosken laavu, and Torkonluikea tulentekopaikka, then Iikoski parkkipaikka with Iikoski tulentekopaikat and Iikoski uimaranta keittokatos, IIKOSKI eräkämppä, and HUOSIUSJÄRVI eräkämppä before closing past Huosilampi laituri 3 and Huosilampi laituri 4 toward Öllöri laituri. MTBreitti.fi stage notes on the same 49 km circuit mention roots, duckboards, short forest-road connectors, and an asphalt finish toward the nature centre after Huosivirta when following their described lap.
The route is marked in blue. Official materials describe one-way arrow guidance for a counter-clockwise sense of travel, although nothing physically blocks riding the other way—yield to hikers because tread is shared. Winter use follows separate maintained winter-bike corridors elsewhere in the park; this summer MTB loop is not groomed for winter riding.
Length & route
The trail is about 49.3 km as one summer mountain-bike loop on our geometry, closing at the Hossa visitor shore. Visit Suomussalmi rounds to 50 km for the same marked circuit. The loop covers most of Hossa National Park except the Julma-Ölkky canyon scenery and other zones where biking is not allowed on foot-only lines—confirm the legal bike layer on the park map.
Getting there
Primary access is Hossan luontokeskus, Jatkonsalmentie 6, 89920 Suomussalmi (postal address also given as Ruhtinansalmi in local listings), with large parking at Luontokeskus pysäköintipaikka. Along the circuit you can also stage from Huosilampi pysäköintipaikka, Keihäslampi pysäköintipaikka, Hossaari parkkipaikka, Huosivirta pysäköintipaikka, Aittojoki pysäköintipaikka, Rytikangas pysäköintipaikka, Kirkasvetinen pysäköintipaikka, Lihapyörre linja-autopysäköintialue, Lihapyörre pysäköintialue, and Iikoski parkkipaikka when you want a shorter day or a linear shuttle.
Good to know
Mountain biking in Hossa is only legal on lines marked for the purpose; non-bike zones and park rules changed when the national park replaced the older recreation-area regime—carry the free visitor-centre map when open and cross-check Luontoon.fi before relying on old GPX files or videos. Prehistoric rock paintings at Värikallio are a foot-access side trip from the Lihapyörre neighbourhood rather than part of the bike loop. For bike hire and guided experiences with direct booking or enquiry links, use the Where to rent equipment and Guided tours sections on this page.
History
Hossa National Park was formally established in summer 2017 as part of Finland’s centenary celebrations, building on decades of managed recreation in the area. In the same 2017 announcement cycle, the Sininen saavutus ride was named to the IMBA EPICS list alongside other new international long-distance singletrack routes.
Where to rent bikes
Hossa-Kylmäluoma rents fatbikes, boats, and other outdoor gear at the Hossa Nature Centre; equipment lists, online booking, and visitor-centre pickup are on Hossa-Kylmäluoma’s rental equipment page. Camping Hossan Lumo at Lumontie 3 offers Trek Farley fatbikes and more during reception hours—prices and sizes are on Camping Hossan Lumo’s rental page. Kainuun Luontoretket hires e-assist fatbikes and other equipment from Joukojärventie 14; models, prices, and contacts are on Kainuun Luontoretket’s equipment hire page.
Guided tours & Experiences
Hossa-Kylmäluoma runs Hossan kansallispuiston esittely, a group introduction to the national park at the visitor centre—typically 45–60 minutes indoors or outdoors—with programme details and booking contacts on Luontoon under that service name. Kainuun Luontoretket publishes guided fatbike excursions for Hossa and nearby terrain on its fatbike excursion page.
Marked guidance follows a counter-clockwise sense of travel; you may ride against it if you yield to hikers on shared tread.
