The fells nearby are excellent terrain for cross-country skiing, sledding and hiking, but somewhat puny for downhill since the maximum differential is on the order of 300 meters. Alas, this is about as good as it gets in flat Finland...
For extreme sledding, the legendary 1.5 km track down from Kaunispää can't be beat. Hold on tight and steer well!
Snow mobiles
If you want to get away from a group and go out on a snow-mobile with a private guide, there are quite a few operators to talk to ; Lapland Delights is one of them and offers ice-fishing in one of the local lakes which includes a snack reindeer lunch cooked in a hunter/fisherman's cabin, great !!
They also arrange viewing the 'Northern Lights' with a private guide, a wonderful way to spend an evening in the Tundra if only the lights could be guaranteed !
