One of things I like about Iceland is the sky here. There is something about the combination of the different types (and height) of clouds, the low angle of the sun and the clarity of the air. It all adds up to a very enjoyable sky-gazing.
It does not matter if one is hiking and enjoying nature, or doing some task outside (and enjoying nature), looking up and pausing every now and again will add to the experience. I believe the clouds to be one of the main reason humans took to thinking in the 3rd dimension (back in the days a few millenniums ago). And still they have the power to pull us further, if we let them.
