I've been to the Alps, too. The Alps are all valleys and mountains. The fells in Lapland are hundreds of times further apart from each other. In between, there is just forest and marshland. Hiking on the designated trails is a good idea. Going to Urho Kekkonen national park or Lemmenjoki national parka are even better ideas. In the former, there are more fells in a smaller area than in Lapland on average. Also, Pallas national park is also a great place to go to if you love breathtaking scenery. The terrain is rugged and you can forget about long-distance cycling, though.
