A day's exploring was not enough, and I could easily have spent weeks travelling the island contemplating its mysterious beauty. It was a deeply refreshing experience to feel so far away from Europe's big polluted cities and so close to nature, albeit a side of nature that I have never experienced before.
The near total absence of trees, due to the predominance of lava fields, combined with the many rivers, waterfalls, mountains glaciers and volcanoes makes for the feeling of being on a different planet, or perhaps Tolken's 'Middle Earth' (but without the orcs!)
In places the red earth made it feel like I was on Mars! I was not surprised to hear the the Apollo astronauts actually used a remote part of Iceland to train for the lunar landing.
The famous Gulfoss waterfall is truly astounding, with a large river crashing through a series of rapids and then literally disappearing into a deep crevice. The amazing thing is that as one stands beside this incredible marvel of nature, there are no touristic, comercial shops or kiosks peddling souveniers or anything to distract from the full presence of the falls. There weren't even any real safety barriers or warning signs beside the rushing water and deep crevice. This was a common feature of all the beautiful places we visited, suggesting a deep respect on behalf of the Icelandic people for their natural environment.
