This dramatic canyon, Jökulsárgljúfur, was formed by the actions of water, fire and ice. Enormous, catastrophic glacial bursts are believed to have carved out the deep ravines and rocky basins, the most famous of which is Ásbyrgi.
The Hljóðaklettar outcrops are the cores of ancient volcanoes, revealed when the river swept away all the loose volcanic material.
The waterfalls on the River Jökulsá á Fjöllum, Selfoss, Dettifoss, Hafragilsfoss and Réttarfoss are powerful and impressive.
The Hólmatungur district is an area of contrasts: crystal clear streams and bubbling brooks cross the land before emptying into the raging, chocolate-coloured torrent. A delicate balance of flora and fauna thrives under the protection of cliffs and scree slopes.
