Somewhere in Iceland. Went there in October, rainy for days and then suddenly, we had a sunny day and it looked like this!!

I was there for the last 3 weeks of September of last year. Out of 21 days, we got to see the lights 3 times. (all near the last few days of our stay). Their is never any guarantee you will some. From I have read, the next few years the conditions will be less ideal.
