Doze off under the Northern Lights. In Finland, nature's most spectacular light show, the Aurora Borealis, can be viewed in a range of purpose-built spaces from glass igloos to luxury suites. The Northern Lights are visible on roughly 200 nights a year – or every other clear night – in Finnish Lapland.
In northern Lapland the lights shine about every other clear night between September and March. In southern Finland they are visible on about 10-20 nights a year. Look to the stars. If you notice that the night sky is clear and starry, your chances of seeing the northern lights are good.
