Suomussalmi has about 350 kilometers of maintained
snowmobile routes.
A permit is required to use snowmobile tracks on state
land. Permits are provided by the Finnish Forest and
Park Service (Metsähallitus) and are valid throughout
the country. Permission must always be obtained to go
snowmobiling on private land. Snowmobilers use tracks
at their own risk. In The Hossa Hiking Area snowmobiles
may not leave marked tracks even on the ice. There
are rental cabins, fireplaces, shelters and wilderness
huts along routes. Wilderness huts are intended for the
use of skiers, hikers, boaters and canoesists.

Snowmobile routes in Suomussalmi and the whole Kainuu region can be seen in the Kainuu outdoors map.
