Markarfljótsgljúfur Canyon is a hidden gem in the Icelandic landscape. It is one of our most impressive and stunning canyons. One reason is the fact that it is placed in the Icelandic Highland and not simple to visit. Although not among the largest canyons in Iceland, it is quite deep, about 200 meters where it is deepest, and the main and most interesting and most accessible part spans about 4 kilometers. The canyon is very impressive and is part of the Highland road Syðri Fjallabak when entered by Emstrur continuing from Fljótshlíð in southern Iceland.
The canyon is believed to be created in a single disaster flood bursting from the famous volcano Katla in Mýrdalsjökull glacier in an eruption under the glacier. If that is correct you will be amazed when looking at the canyon of the enormous power a single flood from an eruption under glacier can create and the devastation it can leave behind. This supposedly occurred about two thousand years ago, so other geological factors have contributed to the canyon since then. Through the canyon floods the river Markarfljót which has also given it a name.
