The (oxymoronically titled) Diamond Circle is a popular tourist route in northern Iceland, encompassing the town of Húsavík, Ásbyrgi Canyon, Lake Mývatn and the Dettifoss waterfall. We could easily have spent several days here, but – with only one available to us – we opted to do the latter half of the circle; and in the process, visited some of the most spectacular sights of our entire trip.
