All of the places in Lapland are ski resorts (apart from Rovaniemi).
And as such all the places have grown from teenyweeny villages to smallish towns.
E.g. in Ruka the whole Ruka village has shifted from its traditional place by Rukajärvi lake to the other side of the fell where the centre of the present-day ski resort is located. The whole Ruka-Kuusamo area has over 40000 beds whereas the original Ruka village has hardly any permanent residents anymore when the construction and development has concentrated on the other side of the fell for decades. However, in the area of the present-day Rukajärvi village there are plenty of holiday cabins.
In Ylläs tourism has swollen the tiny original villages into the present-day centres on both sides of the fell. However, they have still retained some of their orginal characteristics as they are located 3.5 km from the nearest slopes. To give you some figures, there are altogether some 750 permanent residents in the villages of Äkäslompolo and Ylläsjärvi, but there are around 22000 beds scattered around Ylläs and its surroundings.
In Kittilä and Levi there are some 6300 inhabitants most of whom live in the centre of the municipality, not in Levi. Levi is actually located in a village called Sirkka which has under 800 permanent inhabitants, and there are over 24000 beds around Levi!
If you want to have town-like surroundings with wilderness at the doorstep, choose between Levi and Ruka. Ylläs is more peaceful and spread-out. Saariselkä has also a kind of a village centre but it is smaller than Ruka or Levi.
