During our visit in September 2016 we stayed 2 days at Lake Myvatn. It is a breathtaking place especially during fall with lots of things to explore from hiking to natural hot springs. The scenery is just perfect for taking mesmerizing photos. One other thing to do while up there is a trip to the little fisher town of Husavik also known as the whale watching capitol of Iceland. Next time we will spend more time at Lake Myvatn.
