Fjaðrárgljúfur canyon is another of Iceland’s awe-inspiring spectacles that you must see when travelling in the region. The canyon itself measures around 100 metres deep and 2km long with very sheer walls. Probably the most fascinating thing about the canyon (besides its majestic proportions) is the chance to hike and explore inside it (the water level is very low in most parts so this can be done safely). There is a great walking path which leads to the canyons edge and visitors can enjoy a spectacular view of the area above the canyon.
