Two different trips
Yellowknife — The highest aurora odds in North America
Yellowknife’s geomagnetic latitude is the highest of any easily reached aurora city — the oval sits overhead almost every night. Add the flat, dry subarctic interior of Canada’s Northwest Territories and you get legendary sighting rates.
Reykjavík — Aurora over the land of fire and ice
Reykjavík sits just south of the auroral oval, so displays need a touch more geomagnetic activity than in Arctic Norway — but Iceland rewards you with volcanic foregrounds and easy self-drive escapes from city light.
