The most famous day trip from Reykjavik and deservedly so, as it combines history, geology, waterfalls and geothermal activity, pretty much Iceland in a nutshell.
Þingvellirm
Where the original Icelandic parliament, one of the oldest in the world, would meet for a fortnight each year. It’s also where America and Europe literally meet, one of only two places in the world (the other is the Great Rift Valley in East Africa) that continental drift between tectonic plates can be seen. Both those facts I knew before I went but I had no idea what the place looked like or how staggeringly beautiful it would be.
Geysir
Where the word Geyser came from, an interesting collection of geothermal sights, not as colourful or extensive as those at home in Rotorua, but still pretty impressive, particularly the geyser erupting.
Gullfoss
A quite stupendous waterfall, one of the best I’ve seen, enhanced further by rainbows over the falls, and even across the track by the falls.
Faxi
As a bonus we also stopped briefly at this significantly smaller, but still rather lovely waterfall, complete with a special channel to the left for lazy salmon.
Oh Iceland we will be there with you one day soon enough!
