I would choose Iceland, and that is because it's unlike anywhere else on earth. There are other places with glaciers, volcanoes, natural thermal springs etc..but there is a reason producers of sci-fi/fantasy movies often choose Iceland (when the budget allows) to film other worldly or alien landscapes. Game of thrones, Prometheus and Oblivion come to mind, but there are others. I also like that the entire Island (it isn't tiny) has around the same population as a mid sized U.S. city, and since it is fairly isolated in the North Atlantic, the wonders it has to offer won't be choked by thick crowds of tourists.

So yeah, Iceland would be the first stop on my world tour.
