Two different trips

Abisko — Statistically the clearest sky in the auroral zone

Abisko lies in the rain shadow of the Scandinavian mountains, in a microclimate famous for its "blue hole" of clear sky. Combined with a position under the auroral oval, it has one of the highest aurora success rates anywhere on Earth.

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.
