Day 4 presented the opportunity to visit Iceland's "Golden Circle"—Þingvellir, Geysir and Gullfoss—three places of natural and historical interest in close proximity to one another and not too far from Reykjavik. The great advantage of having a car is that you can visit sites at your own pace, rather than being hustled around places of great mystery and beauty at a clip.
Visiting Geysir, from which all other geysers are named, is like walking across the earthen cover of a pot of water on the boil: a novel experience. It's fascinating to see Strokkur spout and the constant hint of sulphurous odours reminds you that you are indeed standing over a subterranean kettle that has bubbled day and night for millennia.
Seeing and photographing Gullfoss had been high on my list of things to do in Iceland since I first became aware of the beautiful waterfall with the optical illusion right-angled drop. Unfortunately, we arrived too late in the day to get any decent light on the falls. It's a fantastic sight but it was never going to translate into anything memorable on my sensor without the all-important late-afternoon sunlight.
And why were we late in getting to Gullfoss? Because we couldn't tear ourselves away from Þingvellir (or Thingvellir) National Park. I have never visited a more magical setting. Where else on earth can you stand with one foot on the American tectonic plate and the other on the Eurasian—remembering all the while that the two are separating? Where else can you gaze into crystal waters and see deep into cracks in the earth's surface? Where else can you walk in the footsteps of the people who established the world's first parliament on the site—over 1,000 years ago?
I don't believe in elves and trolls, but I can see why Iceland's earliest inhabitants did: they lived in a land of legendary scale and wild beauty.
