Booking a cruise takes almost all the travel problems, so that you enjoy sitting back. If you are inland or do not imagine a cruise option, the northern lights tours is available in every major city. In the snow, you can take a trip to the snowmobile and dog-sling outside of the city, which is very far from the man-made light, where the Aurora becomes very bright and charming.
Other ways to get out of the city include hiking and bus tours. If you are not in the north, you can say that it is sometimes less than 40 cold. Celsius or Fahrenheit, it does not matter because they are both similar!
