Ylläs is Finland's biggest ski area, so of course it appeals to skiers and snowboarders. However, this is the perfect travel itinerary for couples, families and groups that all have different interests.
It's a combination of relaxing in Finnish nature, doing some typical Lapland activities and hitting the slopes for some ski- or snowboard fun! There's really something for EVERYONE.
If you want to stick to this 10-day itinerary, you have 5 nights to spend in Äkäslompolo and 2 nights in Ylläs. I can highly recommend doing this, but if you don't have that much time and want to shorten this trip, it's better to choose between either a stay in Äkäslompolo or Ylläs.
