I have an offer to do a trip to Iceland in the lovely warm month of December.

I know what I would be getting into temperature-wise by going that time of year, but I'm curious to know about accessibility. How well are the roads maintained during the winter? I greatly enjoy doing outdoor photography, but if the majority of the sites are snowed in and inaccessible, I won't bother with the trip.

What about the Ring Road - I'm assuming that it's the major road on the island and still well-maintained in the winter?

Are there any "must-see" things that I likely couldn't reach?
