It can be open in January, but severe winter conditions may result in restricted or suspended traffic. The tunnel's year-round design does not guarantee uninterrupted access during heavy snowfall.

No, access is not guaranteed every day. Sissu may be accessible during suitable conditions, but heavy snowfall, road closures, local restrictions or avalanche risks can temporarily prevent tourist visits.
