Koli and North Karelia provide perfect conditions for snow-mobilers: hilly country, lots of snow, and good food. Koli is linked to the regional snow-mobile network, with 1800 kms of trails available. So if you’re fit enough and have the time you could spend a whole week on the trails. Or alternatively just a couple of hours, with or without a guide.
