What I want
I would like to visit one of the national parks in Finland for ~5 days. I am looking for a location that is
- reasonably far away from cities
- has dense forests
- a slightly mountainous area that would enable 1-day hikes that reward you with a view down onto nature over a wide area*
- is north of the arctic circle to experience the polar summer (not sure if this conflicts with the dense forests)
- has at least one lake for canoeing
(in that order of importance)
What I found
The topological map of Finland shows that there are few tall mountains in general:
And pictures from nationalparks.fi see to indicate that hills are all I can hope for:
Photos from Google Streeview also show rather sparse forests:
Question
Can you recommend a national park or nature spot in Finland that would satisfy all the requirements listed above. Time of travel will be the second half of August. As an alternative I thought about flying to Norway or Sweden as they seem to be much more mountainous, but Finland would be the easier solution. Starting point of travel can be Helsinki or Tallinn and can include all means of travel. Renting a car is also possible.
*I don't have professional equipment such as a lightweight sleeping bag or tent so a multi-day hike would be too expensive, as I would have to buy all the equipment.
