In September the Ice Caves of Iceland are still forming. Lots of waterfalls make their way as they form these beautiful caves. Come back in February and I bet this is all frozen over and even more amazing.
Right around the Blue Lagoon and not far from the main airport in Iceland are beautiful mossy covered pieces of lava. The lava in this area is pretty old so the moss has been working at it for quite awhile. You'll see this kind of a scene throughout the country but with the light, and clouds and the contrast on this day it was so lovely.
Hopping on a water taxi and getting out in the bay is a no brainer if you are looking for a great view of Seattle (try this with any city really!).
