One of the major themes of my recent trip to Iceland was waterfalls. Mostly, because there are hundreds!
We have waterfalls in the U.K. but frankly they are drips compared to anything in Iceland! Just along the roadside we passed tens of them every day. Not all waterfalls were created equal though, and some deserved a bit more effort to see. We hiked our way into one of the many reserves on Iceland, Skaftafell National Park, and after 5-6 km were rewarded with the breathtaking Svartifoss:
The columns are caused by the basalt cooling in a specific way – or something like that, there was an information board, but frankly, I was a little distracted.
