Oops!

Dettifoss is supposed to be the most powerful waterfall in Europe - so a slip into the water is going to be a one-way trip! The rocks were really slippery (lots of spray and it had been raining) and there's no such thing as health & safety out in the icelandic wilderness - I was getting very scared watching these guys mucking around by the edge. They moved away pretty quickly after one of them had a wobble!
