For most people, seeing the Northern Lights is a once-in-a-lifetime treat. Finland is perhaps the top country in the world for seeing these blazing curtains of light drape across the sky. Although, at times, the lights can be seen even in the southern most regions of the nation, the best place to see them is in Lapland. In the north, between September and March, visitors are almost guaranteed a show if the sky is clear. A wide range of hotels in the north cater specifically to people wanting to see the lights. Also, the Finnish Meteorological Institute allows you to sign up for free Northern Lights email alerts.
