The region called Lapland stretches out across 3 countries (Finland, Sweden and Norway) and is quite different in each of those countries. From rugged mountain landscapes and treeless tundra in its western and northern parts, Lapland becomes hilly and covered by endless taiga towards the south (and suprisingly much colder in winter, as inland is way colder than the efficiently Gulf Stream-heated coastline). It’s one of the very few easily accessible and fairly populated places on Earth above the Arctic Circle (which geographically marks the limit of the globe’s arctic area where the sun doesn’t set and doesn’t rise for at least one day during the year, a phenomenon also known as midnight sun and polar night). The further you go north, the longer these periods last (for example at North Cape, the sun doesn’t set at all from May 13th to July 29th and doesn’t rise at all from November 18th to January 23rd). Lapland also is one of the best places on Earth together with Iceland to chase the amazing northern lights.
For a special experience in Québec, rent a yurt at Mont-Tremblant National Park (be early, they tend to sell out fast). Go winter for some snowshoeing in beautifully frozen landscapes, or fall for some hiking amongst amazingly coloured foliage.
