The northern lights are weather, not a show. You need dark skies, clear weather and patience, in that order.
Getting there
Fly to Reykjavik between September and March and drive away from the city lights.
Where to stay
A farm guesthouse with a wake-up call when the lights appear.
What I would do differently
I would stay five nights. We saw them on the fourth.

Prices in this guide are what I paid. They move every season, so use them as a rough guide.
