A geologist’s idea of heaven, Northern Iceland is a mammoth collection of thundering waterfalls, green valleys, ancient mountains, and long fjords that stretch their icy arms towards the Arctic Circle. For big-city living, check out Akureyri, Iceland’s second-largest urban area, and get off the beaten track to visit Lake Myvatn, go whitewater rafting, gaze out over lava fields and enjoy whale watching off the north coast.
