Norway is a popular destination for aurora seekers, with Tromsø often at the top of the list. The city is in the Northern Lights zone, and it's located north of the Arctic Circle, making it closer to the northern pole [source: Fjord Travel].
While aurora viewings are never guaranteed, in Tromsø they're pretty close: About half of the city's dark, clear nights boast excellent light shows [source: Hansen]. And, covered in darkness for about nine months out of the year, the aurora can often be seen in the afternoons there, too [source: Fjord Travel].
Hotels in Tromsø will often offer Aurora Borealis wake-up calls, just in case you fall asleep before the lights show up.
