9. Dancing sky lights Kirkjufell, Iceland The ethereal Northern Lights (Aurora Borealis) are visible for eight months a year, from early September to April-end, and your chances of seeing the lights depend on your luck, the clear skies and solar activity. The most common way to see the Aurora Borealis is by taking a guided tour. Auroras have been spotted regularly from Kirkjufell mountain on Iceland’s west coast, and even from the suburbs of Reykjavík. The Ion Hotel’s Northern Lights Bar, close to Reykjavik, features dimmed lighting and wraparound windows, so guests can watch the aurora with drinks in hand.
