The route in Finland starts at Näätämö on the Norwegian-Finnish border and runs down to Virolahti. For much of the journey the route passes through isolated woods and moorland where you really get a feel for Finland’s vastness. On the way you visit many interesting towns and villages, such as Kuhmo, where there is a Winter War Museum. Further south, near the town of Imatra, there is the Border Museum at Immola Garrison, which focuses on the history of defending Finland’s borders.
It's definitely much easier to visit this section of EuroVelo 13 in summer when the long daylight hours enable you can cycle around the clock!
