Both Iceland and northern Scandinavia are within the northern lights zone, however the region is subject to clouds and stormy weather until mid-December.
There is plenty to see and do in three weeks, including The Northern Lights.
Aarhus, Denmark's second city, is now a culture capital.
Our itinerary led us to waterfalls, glaciers, volcanic activity and thermal springs.
Sighting the Northern Lights is worth the wait and the cold.
Both great choices but Copenhagen, definitely.
A few days in Reykjavik gives you easy access to the sights in the south of the island.
Flights between Copenhagen and Reykjavik are great value and this might be a good starting point.
