Skogafoss, Iceland: One of the most breathing-taking, awe-inspiring places I have ever been. Thousands of litres of water rushing past to tumble over the edge, hitting the ground sixty meters below and meandering off into the ocean. Add to this wonder the thunder of an erupting volcano not more than a kilometre and a half away and billowing clouds of ash rushing by overhead... I still have no words. I can only recommend you get there as fast as you can!
