The horses are amazing and very social. They'd actually pose for you if they're bored. Or maybe they're just looking for a snack ... who knows.
As far as the season, it depends on what you want to see. For photography (Auroras and the stars), late summer and winter months are the best, though its obviously a bit rougher. The Aurora season starts in September, which is probably best time to go, as you get a good balance of dark nights and sunny days. In winter (Jan / Feb) its darker much longer, so there is a greater chance for good night photography and great Aurora scenes (in my case through the 10 days there I only saw the lights twice - and 1st time they were so faint I didn't even see them until I saw the preview of a 10-sec exposure on the LCD).
The trick to get the Lights, the Milky Way, and the icebergs all in one shot (which I was not lucky enough to get) likely requires winter time.
Very nice, like them all! (especially horses - they are super-cute)
My daughter stayed in Iceland recently a couple of days on a way to London, and now is trying to convince me to go there.
What would be the best season to visit?
