I've been there in winter as well as in the summer , just rent a good car. Seeing vestrahorn with the aurora on full display is mind blowing. I would say if you aren't a confident drive and not used to driving in snow or ice then stay in the city and do day tours. They're are wonderful onea but renting a car is well worth it.
Her what to bring list did make me laugh .
Is it really bad that I'm so happy she didn't get to see the aurora
The behind the scene pics of the photo shoot makes me wonder how did she get picked to be the cover girl??
