Jagged black mountain ridges veiled in lush green moss. Electric blue rivulets set against black sand deserts. Powerful waterfalls overshadowed by mighty volcanoes. All on a backdrop of ever-white glaciers resting in the distance. Which is to say, Thórsmörk is probably the place that best encapsulated what people might imagine hiking in Iceland would look like. One of the most striking aspects is how the landscapes change over the course of a year—something that is not as pronounced in other parts of the country. Here you can observe how native forests turn red during fall, search for wildflowers in spring and summer, and enjoy the most serene and downright gorgeous winter wonderland (good luck reaching Thórsmörk past October though).
