How long should be Lapland holidays?
To feel Finland and Lapland in its best, it make sense to spend 1 day in Helsinki (for example, between connection flights).
1-2 nights at Glass Igloo.
2-3 nights at classical Finnish log cabin/holiday cottage.
This time should be enough to see and do main Lapland attractions and activities and feel the Arctic.
Total – 5-6 days as an recommendation.
